Technical Field

The invention relates to the field of modifiers, in particular to a cement modifier which can thoroughly mix cement and plant debris together for application.

Background

The cement is a powdery hydraulic inorganic cementing material, is added with water and stirred to form slurry, can be hardened in air or in water better, and can firmly bond sand, stone and other materials together. As an important cementing material, cement is widely applied to civil engineering and building engineering, plate manufacturing and the like for a long time. Plant scraps, such as sawdust, crushed wood, straw, wheat straw, bark, crushed bamboo, coconut scraps, palm scraps, grass and the like, are waste materials after plant processing, and the materials are easy to obtain and low in cost. For decades, many people have been studying to add plant debris into cement slurry to manufacture cement products such as lightweight cement boards, and the like, so as to reduce the cost, the volume weight and the brittleness of the cement products such as the cement boards, and improve the performances of heat insulation, heat preservation, fire prevention, water prevention, and the like, but the problem that the popularization and the application of cement plant debris materials are influenced because the plant debris belongs to organic acidic substances, the cement belongs to inorganic alkaline substances, and the plant debris can slowly release the organic acidic substances to destroy the strength of the cement, even lead the cement to be pulverized, and lead the quality of the cement products such as boards made by mixing the cement plant debris and the like to be poor, the strength to be low, and the service life to be short is not completely solved. Therefore, how to mix cement and plant debris to produce acceptable building materials has been a technical problem which has long plagued those skilled in the art.

Disclosure of Invention

The invention aims to provide a cement modifier (cement paste) to thoroughly solve the problems after mixing of cement plant debris and to sweep technical obstacles for application of cement plant debris mixed materials.

The technical scheme of the invention is as follows: a cement modifier is mainly prepared by mixing the following raw materials in parts by weight:

10-100 parts of silica sol

1-50 parts of a water reducing agent.

Wherein the solid content of the silica sol is 30-50%, and the solid content of the water reducing agent is 30-50%.

Preferably, the cement modifier is prepared by adding one or more of the following raw materials in addition to 10-100 parts of the silica sol and 1-50 parts of the water reducing agent (by weight ratio):

0-50 parts of urea

0-1 part of fluorosilane

0-20 parts of defoaming agent

0-30 parts of waterproof agent

0-20 parts of early strength accelerator

0-10 parts of brittleness-reducing toughening agent

0-10 parts of coupling agent

0-10 parts of vulcanizing agent

0-1 part of colorant.

In the scheme of the invention, the water reducing agent is preferably a polycarboxylic acid water reducing agent; the defoamer is preferably a mineral oil defoamer, but silicone defoamers or synthetic defoamers such as polyether defoamers can also be used; the coupling agent is preferably a titanate coupling agent, and the colorant is preferably a metal oxide pigment, such as an iron oxide pigment.

The cement modifier not only can well mix the cement and the plant debris together, but also can ensure that the cement has the texture of ceramics and the texture of stones, so the cement modifier can be called as a cement ceramifying agent, and is called as cement glue for short. Although the formula is simple and the raw materials are easy to obtain, the cement-plant debris powder has an unexpected effect of completely solving the problem of cement-plant debris which is not solved by the dream of many people for decades and is researched throughout the life. The beneficial effects are as follows:

1. the cement modifier is added into the cement slurry, so that the cement is not afraid of the damage of organic acid and sugar in plant debris after hardening, the strength and the performance of the cement are not damaged and pulverized by the acidity of the plant debris, the cement has excellent resistance to the acidity of the plant debris, and therefore the cement can be well combined with the plant debris, the problems that the strength of the cement and the plant debris is reduced after mixing and pulverized after a long time are thoroughly solved, and the strength of the manufactured cement product is not adversely affected, but has the growth performance, and the strength of the cement product can be increased by one year more than one year with the lapse of time. The manufactured cement plant clastic board and other cement plant clastic products have the advantages of light weight, environmental protection, waste utilization, high strength, small brittleness, good weather resistance, fire resistance, moisture resistance, water resistance, wind, sun and rain resistance, sound insulation, heat insulation, flame retardance, corrosion resistance, bacteria resistance, good machining performance (sawing, drilling, nailing, planing, punching, slotting and the like), no softening, difficult deformation, use like a wood board, easy decoration and the like, have no release of free formaldehyde in the use process, have the most optimal comprehensive performance and function in the prior various board villages, and are widely applied to the aspects of internal and external wallboards, partition boards, floors, decorative boards and the like of buildings at present.

2. The cement modifier is added before the cement slurry is stirred, so that the texture effect of a cement product can be improved, the cement product has the texture of ceramics and stone, and the cement modifier can be widely applied to the manufacture of cement artificial stones which cannot be seen as cement. The cement modifier is added into the cement slurry, so that the surface of the manufactured cement plant debris wallboard is quite bright and beautiful, the appearance color is uniform, mortar batch is avoided, and the engineering and decoration cost is effectively reduced.

3. The cement modifier is added into the cement slurry, so that the bright and bright effect of the cement product can be improved, the cement product is more beautiful, beautiful and durable, and the cement modifier also has the advantages of water resistance, mildew resistance, acid and alkali resistance, corrosion resistance, sun protection, no toxicity, no odor, no stimulation and aging resistance, and is low in cost and easy to obtain the raw materials for manufacturing. Therefore, the cement modifier can be called as cement brightening agent and is used for increasing the brightening effect of cement products.

4. Waste utilization and waste utilization: with the cement modifier, the cement product can be manufactured by using broken wood, straw, wheat straw, bark, sawdust, broken bamboo, coconut fragments, palm fragments and other plant fragments which are regarded as garbage, so that waste is changed into valuable, and various plant resources are fully utilized.
