Technical Field

The invention relates to the field of sports building materials, in particular to a novel plastic environment-friendly silicon PU (polyurethane) field.

Background

Patent CN110804923A provides a construction method of a silicone pu plastic court, in which a plastic component for the construction method is proposed, the plastic component comprises EPDM rubber particles, natural rubber and carboxymethyl cellulose, after the cement is solidified, a layer of cement is further poured on the material, and then an anti-slip layer is sprayed on the cement, which has a problem in the use process because the cement is laid on the material (after solidification), but because the EPDM rubber particles and the natural rubber are both thermally aged due to the heat and the sun irradiation, the EPDM rubber particles and the natural rubber lose elastic cracking after aging, and the rubber materials lose elastic cracking to cause the fracture of the cement layer, and once the fracture of the cement layer, the use value of the entire silicone pu plastic court is lost.

Disclosure of Invention

Aiming at the problems, the invention provides a novel plastic environment-friendly silicon PU field.

The technical scheme adopted by the invention is as follows:

a novel plastic environment-friendly silicon PU field comprises 80-120 parts of EPDM rubber particles, 60-90 parts of natural rubber, 30-40 parts of carboxymethyl cellulose, 38-64 parts of waterborne polyurethane adhesive, 10-20 parts of glass fiber, 20-32 parts of cement stone powder, 10-16 parts of cement defoamer, 15-25 parts of cork particles, 2-3 parts of calcium carbonate powder, 1-2 parts of aluminum oxide powder, 3-5 parts of zinc powder, 4-6 parts of talcum powder and 3-5 parts of paraffin.

Compared with the components provided by the patent CNCN110804923A, the component is added with cork particles, calcium carbonate, alumina powder, zinc powder, talcum powder and paraffin, and after the components are added, compared with the original components, the solidified material prepared by the component has the characteristics of higher aging resistance and longer service life.

Firstly, rubber aging is a necessary thing, and what we can do is only to delay the aging process of the rubber, the rubber aging is mainly caused by five factors of acid, alkali, oxygen, water and heat, and the heat factor cannot be avoided, so the service life is prolonged based on the consideration of acid-base balance, reduction of oxygen content and water content.

The first problem of "water" is that since the EPDM rubber particles and the natural rubber are coated with the aqueous polyurethane adhesive and the cement powder, the particles are substantially isolated from water, and some water vapor will permeate into the coating through the gaps; meanwhile, the paraffin in the formula has the function of keeping certain hydrophobicity after the whole material components are solidified, so that water is not easy to enter;

the second problem of acid-base balance is that some acidic or alkaline gases overflow from the ground surface, although the EPDM rubber particles and the natural rubber are coated by the aqueous polyurethane adhesive, the cement stone powder and other substances, the acidic or alkaline gases still enter through the gaps, so that the calcium carbonate powder, the alumina powder and the rubber particles are mixed in the scheme, when the acidic gases enter, the calcium carbonate powder reacts with the acidic gases, the alumina powder reacts with the alkaline gases, theoretically, the calcium carbonate and the alumina can respectively react with the acidic gases, but when the calcium carbonate and the alumina are mixed together, the acidic gases preferentially react with the calcium carbonate, and when the calcium carbonate reacts with the alumina, the calcium carbonate powder slightly exceeds the alumina powder; acid gas and alkaline gas are reacted through the action of calcium carbonate powder and aluminum oxide powder, so that a relatively neutral environment is kept near the rubber particles; zinc dust also reacts with acid gases, but because it also reacts with some oxidizing gases, it is present in much greater quantities than calcium carbonate and alumina.

The third problem of oxygen is that the scheme adds zinc powder into the mixture, and the zinc powder reacts with oxygen slowly under the action of the zinc powder, so that the oxygen content near the rubber is kept at a relatively low level for a long time, and the rubber can be protected;

the three modes prolong the service life by protecting the rubber, and the cork particles are also one component in the scheme, and the rubber and the cork are mixed, so that the rubber and the cork have good elasticity, the cork particles have good elasticity, and the cork particles are damp-proof and mildew-proof and have long service life. Due to the bonding effect of the glue, the material made of the rubber particles and the cork particles is high in bonding strength after solidification and is not easy to crack. The talc also has the effect of imparting greater rigidity to the overall material composition after solidification.

According to the scheme, the cork particles, the calcium carbonate powder, the aluminum oxide powder, the zinc powder, the talcum powder and the paraffin are added, so that the rubber aging speed of the prepared material is slower after the material is condensed, and the prepared material is long in service life and not easy to crack.
