Novel macromolecule footpath brick making method

Abstract

The invention belongs to the technical field of footpath bricks and in particular relates to a novel macromolecule footpath brick making method. The technological process of the method comprises foursteps of making a surface wearing resistant layer, making a wearing resistant layer, making a reinforcing layer and carrying out demolding. Unsaturated resins which have different shrinkage coefficients and in addition are good in wearing resistance are selected, orthogonal tests are implemented according to crushed glass fiber reinforced plastic granules of different addition amounts and different particle sizes for cast bodies, combinations of appropriate volume shrinkage rates are selected, on the basis of sinking phenomena resulted by addition of fillers of different particle sizes, properties of different layers are affected, viscosities and ratios and the curing time and the addition sequence of the unsaturated resins are adjusted, formulae of the wearing resistant layer and the reinforcing layer are respectively confirmed, rubber granules which are good in slip resistance in case of water are used, a prepared macromolecule footpath brick is good in flouring resistance and brightin appearance color, is matched with ambient environments and modeling requirements, and bulges or other patterns similar to blind track bricks can be made; and the prepared macromolecule footpath brick is matched with ambient environments and modeling requirements, and bulges or other patterns similar to blind track bricks can be made.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of walkway bricks, and specifically relates to a preparation method of a novel polymer walkway brick, which is prepared by blending unsaturated resin and discarded glass fiber reinforced plastic particles as main raw materials, and wear-resistant powder, reinforcing aggregate and pigment as auxiliary materials. The approach to polymer walkway bricks. [0003] Background technique: [0004] 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 wa...
