High-strength Material of the Composite Decking

High-strength material, as the name implies, is a high-strength material. There is currently no clear definition of high-strength plastic-wood composite materials, but in general, high-strength plastic-wood composite materials mean that the mechanical strength is significantly higher than that of ordinary plastic-wood composite materials. The intensity is at least twice the latter. Although bamboo fiber and plastic have good insulation properties, materials with good insulation properties are not the best choice for anti-static or electromagnetic shielding occasions. In summary, it is necessary to improve the appearance, mechanical properties, antistatic properties and electromagnetic shielding of plastic-wood composite materials to enrich their functionality and expand their application fields.

In order to solve the above technical problems, a high-strength plastic-wood composite material with intelligent temperature display effect, the mass parts of its raw materials are: 30-40 parts of plastic, 50-60 parts of plant fiber, 2-8 parts of plasticizer, and silane 0.2-0.4 parts of coupling agent, 0.3-1.2 parts of anti-aging agent, 1.5-5 parts of temperature-sensitive color changing agent, 3-15 parts of inorganic fiber. Plastics are polyethylene (including HDPE, relative density 0.941-0.960g/cm3; LDPE, relative density 0.910-0.926g/cm3; LLDPE, relative density 0.890-0.915g/cm3), polypropylene, One or more of polyvinyl chloride and polystyrene, either pure or recycled; the plant fiber is one of bamboo flour, wood flour, chaff or straw.

The thermochromic agent is made of fully encapsulated nano microcapsule materials, and is one of the red thermosensitizer, blue thermosensitizer, purple thermosensitizer or green thermosensitizer; the red thermosensitizer is produced at 18℃ Red becomes colorless, its model is T-CHALON series, blue temperature-sensitive agent changes from blue to colorless at 33℃, its model is T-CHALON series, purple temperature-sensitive agent becomes colorless at 45℃, and its model is T-CHALON series, the green temperature-sensitive agent changes from green to colorless at 45°C, and its model is T-CHALON series; the inorganic fiber is one of ceramic wool, glass cloth or mineral wool. When the inorganic fiber is ceramic wool or mineral wool, the processed plant fiber is prepared. At the same time, add anti-aging agent, temperature-sensitive color changing agent and inorganic fiber to mix to prepare a mixture; place the obtained mixture in a flat vulcanizing hot press, and set the preheating parameters of the hot press; Carry out hot pressing; finally carry out forced cooling, the temperature is cooled to 70 DEG C, the pressure is removed to take the board, and the high-strength plastic-wood composite material with intelligent temperature display effect is prepared.
