Abstract

The invention discloses a waste straw composite board which is prepared from the following raw materials in parts by weight: 20-30 parts of epoxy glue, 8-12 parts of a modifying agent, 80-100 parts of waste straws, 10-15 parts of a tackifier, 6-8 parts of gypsum, 6-12 parts of shell powder, 2-4 parts of nano zinc oxide, 1-3 parts of nano titanium dioxide, 3-7 parts of a waterproof agent, 7-9 parts of a flame retardant, 8-14 parts of attapulgite and 25-35 parts of water. The waste straw composite board has the characteristics of being high in strength, good in moisture resistance, good in dimension stability, resistant to corrosion, retardant to flame, and attractive, the problems of easy blank dispersion, board sticking and difficult de-molding are avoided, the agricultural straws are greatly used to reduce cost and save resources, continuous production is realized, production efficiency is greatly improved, a process is simple, and the waste straw composite board has a relatively high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural straw utilization, in particular to a waste straw composite board and a preparation method thereof. Background technique [0002] The development trend of wood-based panels is rapidly changing from wood to various wood substitutes as raw materials. Using crop straw as the main raw material to produce composite wheat straw panels has various excellent physical and mechanical properties, surface decoration properties and secondary processing properties, and has become a high-strength environmental protection panel. This type of board is a load-bearing structural material that is completely different from traditional boards. It can be used in construction engineering, packaging and furniture decoration, and has become a revolutionary board that replaces traditional boards. This kind of board has good heat insulation, sound absorption and noise prevention functions, high product strength, insect...
