A kind of preparation method of polymer pavement brick

Abstract

The invention belongs to the technical field of walkway bricks, and specifically relates to a preparation method of a novel polymer walkway brick. The process includes four steps of preparing a surface wear-resistant layer, preparing a wear-resistant layer, preparing a reinforcing layer and demoulding, and selecting different shrinkage coefficients. The unsaturated resin with good wear resistance, according to the casting body, different additions, different particle sizes of FRP crushed particles to do orthogonal experiments, select the appropriate combination of volume shrinkage, based on the precipitation caused by the addition of fillers with different particle sizes The bottom phenomenon affects the performance of each layer, adjust the viscosity, specific gravity and curing time of unsaturated resin and the order of addition, respectively determine the formula of the wear-resistant layer and the reinforcement layer, add rubber particles that are more slippery when exposed to water, and prepare polymer pavement bricks Strong stain resistance, bright color appearance, can be made into protrusions or other patterns similar to tactile bricks according to the surrounding environment and modeling needs; the prepared polymer walkway bricks can be made into raised or other patterns similar to tactile bricks according to the surrounding environment and shape needs other patterns.

Description

Technical field: [0001] The invention belongs to the technical field of walkway bricks, and specifically relates to a preparation method of polymer walkway bricks, which uses unsaturated resin and discarded glass fiber reinforced plastic particles as main raw materials, and uses wear-resistant powder, reinforcing aggregate and pigments as auxiliary materials to prepare high-grade bricks. Molecular walkway brick approach. Background technique: [0002] Walkway bricks or pavement bricks are artificial blocks made of industrial waste or local materials such as concrete, slag and fly ash. The walkway bricks are divided into small bricks, medium bricks and large bricks according to their size and quality. The height is 115mm. Those with a height of -380mm are called small bricks, those with a height of 380-980mm are called medium bricks, and those with a height greater than 980mm are called large bricks. Most of them are small and medium-sized bricks when used. The walkway bricks...
