Embodiment 1

[0035] Composition of raw materials: 207.98 kg of quartz sand with a maximum particle size of less than 1000 microns, 18.06 kg of o-phthalic unsaturated polyester resin, 1.17 kg of titanium dioxide, 0.97 kg of iron yellow, silane coupling agent γ-methacryloxypropane 0.87 kg of trimethoxysilane (KH570), 0.36 kg of methyl ethyl ketone peroxide as a curing agent, 0.05 kg of cobalt naphthenate as an accelerator, and γ-methacryloxypropyl trimethoxysilane as a silane coupling agent (KH570). 0.54 kilograms of nano-silica; These raw materials are prepared by the following preparation process to prepare quartz stone plates.

[0036] Put the above-mentioned o-phthalic unsaturated polyester resin, pigment, silane coupling agent and nano silica into the container, disperse evenly under ultrasonic vibration, and finally put the unsaturated polyester resin mixture into the quartz sand Put in curing agent and accelerator in 2-5 minutes, stir and mix evenly to get resin mixture. Put the abov...

Embodiment 2

[0039] Composition of raw materials: 220.94 kg of quartz sand with a maximum particle size of less than 400 microns, 24.00 kg of o-phthalic unsaturated polyester resin, 1.28 kg of titanium dioxide, 0.20 kg of iron red, silane coupling agent γ-aminopropyl triethoxy Silane (KH550) 0.88 kg, curing agent tert-butyl peroxy-2-ethylhexanoate 0.19 kg, silane coupling agent γ-methacryloxypropyl trimethoxysilane (KH570) modified nanometer Silica 2.52 kg. Prepare these raw materials according to the preparation process of Example 1 to prepare quartz stone plates, but there are the following differences: 0.72 kg of modified nano-silicon dioxide is mixed with unsaturated polyester resin, and the remaining 1.8 kg is mixed with quartz stone sand, and sealed When the agitator stirs the quartz sand, the stirring speed is increased by about 20%, the vacuum vibration is pressed for 240 seconds, and the temperature of the curing furnace is 85-90°C. According to the quartz stone plate prepared in...

Embodiment 3

[0041] Composition of raw materials: 243.11 kg of quartz sand with a maximum particle size of less than 4500 microns, 24.72 kg of isophthalic unsaturated polyester resin, 1.43 kg of titanium dioxide, 0.31 kg of iron black, silane coupling agent γ-glycidyl ether oxypropyl trimethyl 1.28 kg of oxysilane, 0.62 kg of curing agent cyclohexanone peroxide, 0.1 kg of accelerator cobalt naphthenate, and 8.54 kg of nano silicon dioxide. Prepare these raw materials according to the preparation process of Example 1 to prepare quartz stone plates, but there are the following differences: 0.49 kg of nano silicon dioxide is mixed with unsaturated polyester resin, and the remaining 8.05 kg is mixed with quartz stone sand, and the agitator is closed When stirring the quartz sand, the stirring speed is increased by about 40%, and the vacuum vibration is pressed for 150 seconds. According to the quartz stone plate prepared in this way, after testing, the water absorption rate is 0.01%, and the d...

Abstract

The invention discloses a composite nano silicon dioxide / quartz stone plate product and a preparation method thereof. The composite nano silicon dioxide / quartz stone plate product is prepared from the following components and raw materials in parts by weight: quartz stone sand, pigment, a silane coupling agent, nano silicon dioxide, unsaturated polyester resin, a curing agent and a certain amountof accelerant by the steps of mixing, adding to a mold, carrying out vibration compaction, curing, determining thickness, grinding and polishing and carrying out other working procedures. The invention also discloses a preparation process of the composite nano silicon dioxide / quartz stone plate product. According to the invention, the prepared composite nano silicon dioxide / quartz stone plate is a composite quartz stone plate product which is a large network structure formed by tight embedding and chemical bond cross-linking of all the components; and the prepared composite quartz stone plateproduct has the advantages of high silicon dioxide content, high strength and hardness, ultraviolet aging and thermal aging resistance, high fire retardancy and high heat insulating property, compactand glabrous surface and durability. The use range of the quartz stone plate is enlarged.

Description

technical field [0001] The invention relates to the technical field of an artificial building decoration material and a manufacturing method thereof, in particular to a nano-silica composite quartz stone plate product and a preparation method thereof. Background technique [0002] As we all know, quartz stone slabs are made of natural quartz stone, unsaturated polyester resin and auxiliary materials as the main raw materials. They are widely used in public buildings and home decoration (kitchen countertops, washstands, kitchen and bathroom walls, Dining table, coffee table, window sill, door cover, etc.) field. However, compared with foreign advanced enterprises, the hardness, strength, compactness, smoothness, impermeability, toughness, flame retardancy, anti-ultraviolet aging and heat aging of quartz stone plates produced by Chinese manufacturers still have large gaps. The gap limits its scope of use. [0003] Chinese invention patent application CN101337805A discloses a...
