Abstract

The invention relates to anti-fouling and anti-cracking artificial marble and a preparation method thereof, and belongs to the technical field of artificial stone preparation. The preparation method comprises the following steps: firstly, bamboo splits are used as a raw material, steam explosion fiber breaking is performed to obtain steam explosion fibers rich in hydroxyl groups on the surfaces, then surface corona treatment is performed on the steam explosion fibers to obtain modified fibers, then the modified fibers are used as a template, and calcium sulfate whiskers are deposited on the surfaces of the modified fibers to obtain fibrous calcium sulfate whiskers; then sodium silicate and hydrochloric acid react to generate orthosilicic acid precipitates which are adhered to the surfaces of the fibrous calcium sulfate whiskers, then hydrolysis is carried out at high temperature and high pressure to generate nano silicon dioxide, the nano silicon dioxide coats the surfaces of the fibrous calcium sulfate whiskers, and silicon-coated modified fibrous calcium sulfate whiskers are obtained; and curing is performed under the action of a curing agent, finally, the anti-fouling and anti-cracking artificial marble is prepared, and the anti-fouling and anti-cracking artificial marble has excellent anti-fouling and anti-cracking performance and is wide in application prospect.

Description

technical field [0001] The invention relates to an anti-fouling and anti-cracking artificial marble and a preparation method thereof, belonging to the technical field of artificial stone preparation. Background technique [0002] At present, artificial marble is prepared by blending natural stone powder, mineral or resin slices and other additives in synthetic resins such as acrylic resins, unsaturated polyester resins and epoxy resins, or cement. After stirring, grinding and polishing Made of artificial marble, so artificial marble has many characteristics of natural marble. There are usually four types of artificial marble commonly seen on the market: cement artificial marble, polyester artificial marble, composite artificial marble, and sintered artificial marble. [0003] Aluminum hydroxide powder is generally used as the filler of artificial stone resin in the market, but because aluminum is an important raw material for the national economy and the people's livelihood...
