Light high-strength ABS wood-plastic foamed board and preparation method thereof

Abstract

The invention provides a light high-strength ABS wood-plastic foamed board and a preparation method thereof. The wood-plastic foamed board is prepared from the following components in parts by weight:20-30 parts of ABS resin particles, 10-20 parts of maleic anhydride grafted ABS resin particles, 40-60 parts of wood flour, 5-10 parts of coated flame-retardant polypropylene fibers, 5-7 parts of modifier and 2-5 parts of foaming agent and 0-6 parts of a filler. Reasonable raw material selection and self-made pretreatment of part of raw materials are carried out, the reaction combination effect between the materials is effectively improved and the performance effect is higher; and the ABS is adopted as a board substrate, the comprehensive quality is good, the applicability is high, the prepared board is light, high in strength and excellent in corrosion resistance, mildew resistance, acid and alkali resistance, water resistance, heat preservation, flame retardance and the like, the mechanical property is remarkably improved, and the popularization and application value is high.

Description

technical field

[0001] The invention relates to the technical field of wood-plastic boards, in particular to a lightweight high-strength ABS wood-plastic foam board and a preparation method thereof. Background technique

[0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection new decorative material has both the performance and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. Because wood-plastic panels have many advantages, such as excellent water resistance and corrosion resistance, good dimensional stability, flexible production process, and little damage to equipment, they can also be made from recycled waste wood and plastics, and can be recycled Therefore, as a new type of engin...
