Problems solved by technology

[0003] At present, artificial quartz stones on the market mainly use unsaturated resins or unsaturated resins added with acrylate monomers as bonding materials, and the resin content is usually about 10% or higher, which makes it easy to produce cracks during use. Scratches, reducing its surface finish, pollution resistance, and poor aging resistance, especially corrosion resistance, yellowing will occur after long-term use, and lead to reduced strength or even cracks

Embodiment 1

[0028] The artificial quartz stone described in this embodiment uses raw materials including 5.0wt% bisphenol A vinyl ester resin, 0.3wt% methyltriacetoxysilane, 0.2wt% triallyl isocyanurate Ester, 0.8wt% of cycloaliphatic epoxy bis(2,3-epoxycyclopentyl) ether, and the balance of quartz sand. As a passivator, it is demetallized by adding demetallized ion colloidal silica, polyvinyl alcohol (molecular weight is about 50,000) and fluozirconic acid in deionized water under stirring conditions. The content of ionic colloidal silica is 25.0wt%, 0.1wt% fluozirconic acid, and 5.0wt% polyvinyl alcohol (molecular weight is about 50,000).

[0029] The preparation method of the artificial quartz stone of the present embodiment comprises the following steps:

[0030] 1. Batching according to the above raw material ratio, and then using a mixer to stir and mix evenly to obtain a mixture;

[0031] 2. Use the cloth truck to spread the mixture evenly automatically;

[0032] 3. Turn on the ...

Abstract

The invention relates to high-light and anti-fouling artificial quartz stone and a preparation method thereof and belongs to the technical field of building materials. The high-light and anti-fouling artificial quartz stone is prepared through following technological steps: (1), compression moulding: vinyl ester resin, organoacetoxysilane, triallyl isocyanurate, cycloaliphatic epoxy resin and the balance of quartz sand are mixed uniformly and then subjected to compression moulding by a pressing machine, and the artificial quartz stone is obtained; (2), surface passivation: the artificial quartz stone is coated with a passivator through rolling, and then heating curing is performed, wherein the passivator comprises colloidal silicon dioxide with metal ions removed, zirconic acid, polyvinyl alcohol and the balance of water. The artificial quartz stone is rigid in texture and high in smooth finish, and has excellent wear resistance, impermeability, corrosion resistance and fouling resistance, and the content of the quartz sand in the artificial quartz stone can be higher than 93%.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically, the invention relates to a high-brightness and antifouling artificial quartz stone and a preparation method thereof. Background technique [0002] Artificial quartz stone (or diamond / corundum) originated in Spain. It was called Celite when it entered China in 2005. When artificial quartz stone was recognized by more and more consumers, in 2006, some people in China began to develop artificial quartz. Stone, in 2007, many manufacturers have launched domestic artificial quartz stone. As a new type of artificial building material, artificial quartz stone has incomparable advantages of natural stone in terms of moisture resistance, acid resistance, and splicability. Today, as natural stone resources are becoming increasingly depleted, artificial quartz stone is the best substitute. At the same time, artificial quartz stone can use waste glass as raw material, thus ...
