Embodiment 1

[0030] A calcium sulfate whisker composite quartz stone plate product, comprising the following materials in parts by weight: 30% of quartz particles, 29.7% of glass particles, 15% of quartz powder, 5% of pigments, 0.8% of silane coupling agent, unsaturated 10% polyester resin, 8% anhydrous calcium sulfate whiskers, 1.5% curing agent.

[0031] The size of quartz particles is 0.18-10mm, the size of glass particles is 0.18-10mm, and the size of quartz powder is 0.005-0.18mm. Using raw materials of this size can better disperse anhydrous calcium sulfate whiskers into resin materials and improve the performance of resin-based materials. .

[0032] The curing agent is a combination of one or more of tert-butyl peroxide 2-ethylhexanoate, methyl ethyl ketone peroxide, tert-butyl peroxybenzoate and fatty polyamines.

[0033] Anhydrous calcium sulfate whiskers, the length is 50-200um, diameter 0.2-4um, CaSO4 content ≥ 98%, whiteness ≥ 92%, refractive index 1.585, water solubility 22 ℃...

Embodiment 2

[0043] This embodiment is roughly the same as Embodiment 1, and the similarities will not be repeated here. The difference is:

[0044] A calcium sulfate whisker composite quartz stone plate product, comprising the following materials in parts by weight: 40% of quartz particles, 24.7% of glass particles, 20% of quartz powder, 0.1% of pigments, 0.2% of silane coupling agent, unsaturated 8% polyester resin, 6% anhydrous calcium sulfate whisker, 1% curing agent.

[0045] A preparation method of calcium sulfate whisker composite quartz stone plate product, comprising the following steps:

[0046] (1) Evenly disperse the calcium sulfate whiskers into the resin material, using the following dispersion method: first disperse the calcium sulfate whiskers into the pigment, silane coupling agent, unsaturated polyester resin, curing agent at a ratio of more than 10% Make a masterbatch, then add the masterbatch into the unsaturated polyester resin and dilute to a certain ratio by high-sp...

Abstract

The invention discloses a calcium sulfate-whisker compounded quartz stone board product, which comprises the following materials in parts by weight: 58-75% of particle raw material, 10%-25% of quartz powder, 0.01%-10% of pigment, 0.1%-1% of silane coupling agent, 8%-12% of unsaturated polyester resin, 5%-10% of anhydrous calcium sulfate, and 0.8-2% of curing agent, wherein the particle raw material is one or two selected from quartz particles and glass particles. The product is an environment-friendly novel decoration material which has high property and no radioactive contamination, can be recycled, and has the characteristics of gay colors, high finish degree, uniform color, pressure-resistance and abrasion-resistance, good toughness, compact structure, low water absorption, corrosion-resistance, high strength, impact-resistance, innocuousness and zero radiation, and the like.

Description

technical field [0001] The invention relates to the field of building materials, and more specifically relates to a high-performance, green and environment-friendly calcium sulfate whisker composite quartz stone plate product and a preparation method thereof. Background technique [0002] Resin-type artificial stone is mainly a stone product made of unsaturated polyester as a binder, adding various fillers, pigments, curing agents, and initiators, stirring, molding, curing, cutting, and polishing. [0003] Compared with inorganic artificial stone, resin artificial stone has its unique advantages: [0004] First of all, its low water absorption and good bending resistance have improved the brittleness of natural stone; [0005] Secondly, resin-type artificial stone is easy to process, and can be made into decorations of various colors or special shapes; and it is easy to carry out secondary processing and seamless sealing. [0006] However, resin-type artificial stone still...
