Problems solved by technology

But these composite boards have their own defects. For ceramic tile marble composite boards, because large tiles are easy to bulge when fired, it is impossible to make larger composite boards, and the cut tiles cannot be reused; for aluminum honeycomb marble composite boards, due to Aluminum products are relatively expensive and cannot meet the initial expectations of cost reduction; while polyurethane foam has low strength and cannot meet the requirements for use

Abstract

The invention provides a processing method of a marble polypropylene composite slab. The marble polypropylene composite slab is formed by bonding a marble slab and a modified polypropylene slab through an adhesive. The invention provides two technical schemes, wherein one technical scheme is characterized by using the modified polypropylene slab, and three modifying methods are provided for the polypropylene slab: 1, carrying out grafting copolymerization on polypropylene and maleic anhydride; 2, carrying out melt blending on the polypropylene and a polar polymer; 3, firstly carrying out grafting copolymerization on the polypropylene and the maleic anhydride, and then carrying out melt blending on a grafted copolymer of the polypropylene and the maleic anhydride and the polar polymer; the other technical scheme is characterized by preprocessing the surface of the marble slab by using a coupling agent. The marble polypropylene composite slab prepared by the processing method has the advantages of flexibility, bending performance, difficulty in breaking, recoverability, low cost, light weight, environment protection and corrosion resistance, and can be used under various environments and occasions.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a marble-polypropylene composite board. Background technique [0002] Marble slabs have unique texture and color, and have the characteristics of high wear resistance, high finish, waterproof and anti-corrosion, etc. Bright and generous marble tiles are often used in densely populated grounds such as homes, hotels, restaurants, subway stations, airports, stations, docks, etc. wall decoration. But marble slabs are expensive, about $4 to $8 per square foot. Marble is porous, and substances such as ground acid can easily pass through these gaps, eroding the surface of the marble and discoloring it. [0003] Therefore, in view of the above-mentioned defects of marble, a variety of marble composite panels have appeared in the market, such as ceramic tile marble composite panels, aluminum honeycomb marble composite panels, polyurethane foam marble co...
