High-strength toughening glue, preparation method of high-strength toughening glue and preparation method of A2-level inorganic mineral plate

Abstract

The invention discloses a preparation method of an A2-level inorganic mineral plate, high-strength toughening glue and a preparation method of the high-strength toughening glue. The preparation method of the A2-level inorganic mineral plate comprises the following steps: selecting the following powder by weight: 15-30 parts of aluminium hydroxide, 10-20 parts of magnesium hydroxide, 40-50 parts of silica powder, 60-70 parts of quartz sand, 10-20 parts of diatomite, 10-20 parts of clay, 10-15 parts of talcum powder, and 2-3 parts of glass fiber; adding the high-strength toughening glue and water for mixing, and gradually increasing the temperature to repeatedly roll and brake after uniformly mixing to obtain the A2-level inorganic mineral plate. The high-strength toughening glue is self-made, so that the sticking of the glue is excellent; the plate is prepared from inorganic minerals, is non-toxic and environment-friendly, and is wide in raw material source, the safety of the plate is improved, and the production cost is reduced; through the repeated braking and rolling, air in the plate is easily discharged from the plate, the rolled plate is compact, the production process is simple, and the production is easy.

Description

technical field [0001] The invention relates to a building material decoration, in particular to a high-strength toughening glue and a preparation method thereof, and a method for preparing an A2 grade inorganic mineral board by using the high-strength toughening glue. Background technique [0002] The panels used in existing decorative building materials are mainly aluminum-plastic composite panels, copper-plastic composite panels, stainless steel and plastic composite panels. It is extruded in the machine, and then formed into a plate through the grinding head, and the thickness of the plate is controlled by three wheels. In the natural space, the temperature of the plate is cooled by adding water, and it is coiled at room temperature to make a plate. [0003] After the existing plastic (PE) core material is formed, it is compounded with aluminum plate, stainless steel plate and copper plate, and finally made into finished products for the market. This kind of board has t...

Problems solved by technology

This kind of board has the following disadvantages: PE has a low melting point and poor fire resistance; the melting point of PE is 112°C-140°C, and it is easy to decompose and burn when the temperature is 300°C, and produces a large amount of toxic gas during combustion, which is likely to endanger the lives of consumers. property safety
