Technical Field

The invention belongs to the field of plate product processing, and particularly relates to a method for forming patterns on a plastic plate.

Background

As is well known, the pattern on the surface of plastic sheet material is formed by embossing roller or chemical etching when the sheet material is not cooled and set. The method for forming the surface patterns uses the template in the processing process, thereby invisibly increasing the process flow, greatly improving the production cost and ensuring that the pattern forming quality is not high.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a processing method which is time-saving, labor-saving and labor-saving, can directly form natural patterns on the surface of a plastic plate and has stable product quality.

The invention is realized by the following method, namely a method for naturally forming patterns on the surface of a plastic plate. Adding metal powder into raw materials for processing the plastic plate, and forming the plastic plate with natural patterns on the surface after crushing, mixing, polymerizing and high-temperature hot pressing the raw materials. The metal powder has large heat conductivity coefficient and particle size of about 65 meshes, and is added after the raw materials are crushed and mixed.

The invention has the advantages that the metal powder is added into the raw material, and when the plate is formed, the plastic plate is rapidly cooled on the surface by utilizing the higher heat conductivity coefficient of the metal and naturally shrinks to form irregular surface patterns.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

Waste materials such as plastics, chemical fibers, plant fibers and the like are used as processing raw materials of the plastic plate, metal powder with a high heat conduction system is added into the waste materials, the particle size of about 65 meshes is generally the best, and the plastic plate with natural patterns on the surface is formed through the steps of mixing, polymerization, high-temperature hot pressing and the like. The metal powder can be added during the mixing of the raw materials, or can be added after the raw materials are crushed. The metal powder is added into the raw material, when the plate is formed, a heat conduction system with higher metal is mainly utilized, the surface of the plastic plate is rapidly cooled, the surrounding shrinkage of the metal powder is realized, and finally beautiful patterns are formed on the surface of the plastic plate.

The method can form beautiful patterns in the production process of the plate, saves the redundant step of reusing embossing rollers or chemical etching in the prior art, saves time and labor, and ensures that the formed surface patterns have stable quality and are not easy to deform.

Modifications may be made in the art without departing from the principles of the invention and these modifications are to be considered within the scope of the invention.
