Problems solved by technology

The disadvantage of fiberboard is that there is a texture on the back, resulting in unequal surface areas on both sides of the board. After moisture absorption, the board is warped and deformed due to the difference in expansion force; the surface of the hard board is hard, difficult to nail, and poor water resistance; Some disadvantages, but the cost is higher

Abstract

The invention discloses an environment-friendly anti-bacteria mold-proof composite fiber board and a preparation method thereof. The environment-friendly anti-bacteria mold-proof composite fiber board is prepared from, by weight, 5-8 parts of poplar leaves, 5-10 parts of wood flour, 5-9 parts of crop stalk, 3-6 parts of kieselguhr, 7-15 parts of polyurethane, 5-10 parts of polyether, 5-8 parts of acetate fiber, 2-4 parts of DL-benzylsuccinic acid, 3-5 parts of ethylene glycol monostearate, 1-3 parts of melamine phosphate, 2-6 parts of styrene-acrylic emulsion, 1-4 parts of a silane coupling agent, 2-3 parts of an antioxidant and 2-5 parts of an adhesive. The prepared environment-friendly anti-bacteria mold-proof composite fiber board is stable in character, resistant to mold and environmentally friendly, and causes no pollution to environment.

Description

technical field [0001] The invention relates to the field of materials, in particular to an environment-friendly antibacterial and mildew-proof composite fiber board and a preparation method thereof. Background technique [0002] Fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber, applied with urea-formaldehyde resin or other suitable adhesives, and adhesives and (or) additives can be applied during the manufacturing process. my country's fiberboard production started in the 1970s, developed in the 1980s, and took off in the 1990s. After entering the 21st century, the output of fiberboard has increased significantly. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. The development of fiberboard production is an effective way to comprehensively utilize wood resources. It takes about 2.5 to 3 cubic meters of wood t...
