Problems solved by technology

However, due to the poor compatibility between halogen-free flame retardants and thermoplastic resins, it is not easy to disperse in the resin, even if dispersed, the affinity is not good
Most domestic enterprises adopt the method of coupling agent to directly mix plastic powder, magnesium hydroxide or aluminum hydroxide powder, coupling agent and other additives, but the dispersion is not easy to be uniform, the flame retardant efficiency is low, and a higher filling amount is required. ills
In order to improve the coupling degree, there are magnesium hydroxide flame retardants processed by powder spraying and atomization process in foreign countries. The performance is better, but the production equipment process is more complicated.

Embodiment 1

[0034] Preparation of modified nano aluminum hydroxide composite flame retardant:

[0035] (1) Add 100g of aluminum hydroxide powder, 200mL of deionized water and 15g of silane coupling agent solution into a high-shear emulsifier, and fully stir at 80°C for 60 minutes to make aluminum hydroxide containing silane coupling agent Aluminum hydroxide slurry with 1.5% powder mass. The silane coupling agent solution is an ethanol solution with a mass concentration of 10%.

[0036] (2) The above-mentioned aluminum hydroxide slurry is pumped to a two-stage stirring ball mill, and ground for 2 hours.

[0037] (3) The aluminum hydroxide slurry after the two-stage grinding is pumped to a spray dryer for dehydration and drying to obtain a modified nano aluminum hydroxide powder.

[0038] (4) Add 80g of modified nano-aluminum hydroxide, 40g of borax, 15g of modified nano-bentonite, 2g of silane coupling agent, and 4g of water glass into the reaction kettle, heat at 100-130°C for 1-3h, and...

Embodiment 2

[0040] 1) Ingredients, the raw material formula is: by mass parts: 65 parts of 0.075-5mm quartz particle raw materials, 55 parts of 0.075-5mm particle raw materials, 30 parts of 0.005-0.045mm quartz powder; 15 parts of polyurethane resin; vinyl triethoxy 0.15 part of silane; 0.15 part of dibenzoyl peroxide; 12 parts of modified nano-aluminum hydroxide composite flame retardant prepared in embodiment 1 are prepared and weighed by formula;

[0041] 2) Stirring, the mixing process is relatively simple, just mix the raw materials such as resin, coupling agent, curing agent and flame retardant pigment in a special mixing tank and mix them until they are evenly mixed.

[0042] 3) Fabric, spread a layer of kraft paper or silicone skin with the same specifications as the mold on the conveyor belt, place the mold on the laid kraft paper, put 4 strips of kraft paper inside the four sides of the mold, and then put 4 strips of silicone, The height should be 3mm higher than the mold plate,...

Abstract

The invention relates to a flame retardant artificial quartz stone board and a preparing method thereof. A modified nanometer aluminum hydroxide composite flame retardant is adopted as a flame retardant and greatly enhances high-temperature resistance and flame retardance. Artificial quartz stone prepared by the method has excellent flame retardance, does not crack under strong-fire burning at a high temperature of 800 DEG C and has good surface luster and low adhesive force. Surfaces of the quartz stone are not liable to be contaminated by combustion ash. The artificial quartz stone board is particularly suitable for application in fire fighting and explosion-proof places, and has potential value for ensuring life and property safety.

Description

technical field [0001] The invention relates to an artificial quartz stone plate and a preparation method thereof, in particular to a flame-retardant artificial quartz stone plate and a preparation method thereof. Background technique [0002] Artificial stone is a new type of non-radioactive, non-polluting, reusable, green and environmentally friendly building interior decoration material. As a new strategic health and environmental protection product in line with the country's sustainable development, it was introduced into the domestic market in the 1980s. The artificial stones currently on the market are mainly organic artificial stones with polymer resin materials as adhesives, which are divided into three categories: artificial marble (hereinafter referred to as artificial granite), artificial quartz stone and acrylic. Although my country's artificial stone industry started late, after more than ten years of rapid development, it ranks among the top in the world in te...
