Abstract

The invention discloses a high-temperature-resistant wood-plastic composite material and a preparation method thereof. The high-temperature-resistant wood-plastic composite material comprises components in parts by weight as follows: 80-120 parts of mulberry twigs, 50-70 parts of waste plastic, 20-35 parts of modified phenolic resin, 10-15 parts of silicone rubber, 3-5 parts of glass fibers, 5-8 parts of sepiolite fibers, 4-7 parts of maleic anhydride, 3-6 parts of nanometer aluminum oxide, 3-6 parts of a zinc borate flame-retardant, 5-7 parts of a 5571 light stabilizer and 4-6 parts of a butyl hydroxyanisole antioxidant. The preparation method comprises technological steps of modifying pretreatment, high-speed mixing, hot-press molding and cooling setting. The waste plastic, the modified phenolic resin and the silicone rubber are used as main raw materials, the cost is reduced, and the problem of environmental pollution caused by waste is solved. The obtained wood-plastic composite material has the advantages that the material is good in stability at high temperatures, high in compressive strength and high in abrasion resistance and does not deform easily, the cost is reduced, and the like; the wood-plastic composite material also has the advantages that the processing technology is simple, the processing time is short, the cost is low and the like, and is applicable to industrial production.

Description

Technical field [0001] The invention involves the field of chemical materials technology, especially a high -temperature wood -resistant wood plastic composite material and its preparation methods. Background technique [0002] The reserves of unable renewable resources on the earth are very limited. With the rapid development of the plastic industry, the "white pollution" caused by plastic products has brought great harm to human production and living environment.In order to solve the shortage of raw materials and environmental problems, people gradually transfer their eyes to the renewable resources on the earth.Plant fiber material is a natural polymer material, a resource that is inexhaustible and inexhaustible.The potential advantages of plant fiber for composite materials are increasingly attracted people's attention. It is low in price, low density, high elastic modulus, similar to inorganic fiber, and its biodegradation and regeneration are the most prominent.The advantag...
