Problems solved by technology

[0002] With the improvement of living standards, people put forward higher requirements for decorative panels in addition to aesthetics and timeliness, as well as functionality and environmental protection. Currently, interior wall decorative panels are frequently used, including man-made panels and natural wood panels. Stone boards, plastic boards, etc. Among them, man-made boards are better in decoration, but a large amount of glue will be used in the production process, which will seriously pollute the indoor environment and cause harm to human health; while natural wood boards are green and environmentally friendly, but they are extremely flammable and have extreme Big safety hazard; stone slabs have compact structure, high compressive strength, good water resistance, wear resistance and durability, and natural texture. It may contain radioactive elements, which also have hidden dangers that endanger human health; plastic sheets can be processed into various patterns, and the colorful concave-convex patterns are full of artistic and decorative effects, and are easy to clean, but plastic sheets are flammable and not environmentally friendly

Abstract

The invention provides a composite mineral plate. The composite mineral plate is prepared from the following raw materials in parts by weight: 45 to 60 parts of diatomite, 5 to 12 parts of zeolite, 15to 20 parts of jade powder, 10 to 15 parts of ash calcium, 5 to 10 parts of polyethylene and 1 to 3 parts of wood fiber. The preparation method comprises the following steps: 1) mixing: weighing desired parts by weight of the above raw materials, putting the raw materials into a mixer, and carrying out uniform mixing to obtain a mixture; 2) granulation: fusing and extruding the mixture in a screwextruder to obtain granules, wherein fusion temperature is 60-70 DEG C, and fusion time is 15-20 minutes; 3) pressing: pressing and molding the granules in a pressing machine to obtain a plate; and 4) cooling: cooling and curing the plate. The composite mineral plate obtained in the invention is beautiful, decorative, green and environment-friendly and has a free formaldehyde content of less than0.005 mg / kg, heavy metals are not detected in the composite mineral plate, the mildew-proof grade of the composite mineral plate is zero, and the composite mineral plate is fireproof and flame-retardant, and can well meet the requirements of modern people for environment-friendly decoration.
