Problems solved by technology

However, the compatibility between halogen-free flame retardant and resin is poor, and it is not easy to disperse in resin. Even if dispersed, the affinity is not good, so the performance of the final flame-retardant quartz stone plate is greatly reduced.

Abstract

The invention discloses a flame-retardant quartz plate. The flame-retardant quartz plate is prepared from the following components in percentage by mass: 25 to 30 percent of quartz powder, 40 to 45 percent of a particular raw material, 10 to 15 percent of ceramic powder, 1 to 2 percent of a silane coupling agent, 1 to 2 percent of a curing agent, 0.5 to 1 percent of ammonium ferrous sulfate, 0.5 to 1 percent of tert-butyl hydroquinone, 1 to 3 percent of a flame retardant and 10 to 15 percent of unsaturated polyester resin. According to the flame-retardant quartz plate disclosed by the invention, the ammonium ferrous sulfate and the tert-butyl hydroquinone are added, so that the compatibility between an inorganic flame retardant and unsaturated resin can be improved, all raw materials can be uniformly mixed, the interfacial adhesion property is strong, an internal gap is smaller, and the bonding is closer; the obtained flame-retardant quartz plate has excellent abrasion resistance and also has excellent mechanical performance and higher bending strength, and meanwhile, the flame-retardant quartz plate has good flame retardant effect and lower water absorption.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a flame-retardant quartz stone plate and a manufacturing method thereof. Background technique [0002] Artificial quartz stone is a new type of polymer material which is mixed with natural quartz sand, quartz powder, resin and pigment and processed by special equipment. Quartz stone is composed of more than 80% of natural quartz and about 10% of colorants, resins and other additives for adjusting bonding and curing. The board processed by the production method depends on the type. It has a hard texture (Mohs hardness 5-7), a dense structure (density 2.3-2.5g / cubic centimeter), and has incomparable wear resistance, pressure resistance, High temperature resistance, corrosion resistance, impermeability and other characteristics. At present, quartz stone products are mainly used in kitchen countertops, bathroom countertops, bar counters, coffee tables, floors,...
