Abstract

The invention discloses a compression molding fibre-reinforced straw plastic combined cabinet slab which is prepared from the following raw materials according to parts by weight: 0.2-0.6 part of modified crop straw fibre or straw fibre wood powder thereof, 0.1-0.2 part of PET or nylon waste silk, 0.05-0.2 part of melamine, 0.05-0.2 part of modified talcum powder, 0.01-0.05 part of chemical assistant and 0.3-0.6 part of polyolefin thermoplastic resin. The invention also discloses a preparation method thereof. The cabinet slab of the invention is formaldehyde-free environment-protection material and has wood texture and handling characteristics, and the machinery mechanics strength thereof exceeds that of good-quality solid-wood slabs; and in addition, the cabinet slab does not adsorb water and has the functions of low coefficient of thermal expansion, moisture prevention, mildew prevention, aging prevention, combustion prevention, reuse and the like and is an ideal cabinet slab wood replacing material.

Description

technical field [0001] The invention relates to a molded fiber reinforced straw-plastic composite cabinet board and a preparation method thereof. Background technique [0002] Cabinet boards are a huge market in the home improvement industry, and the safety and economic applicability of flat board materials for family cabinets are also issues involving the livelihood of thousands of households. At present, the boards used to make cabinets in my country include fire-resistant boards, paint boards, PVC molded blister board, acrylic board, moisture-proof particle board, etc. Except for solid wood boards, most of the boards are made of density board (fiberboard) or particle board as the core material and then veneered or surface coated. For example, the fireproof board series with a large market share is made of particleboard as the core material and hot-pressed with melamine-impregnated paper veneer. This type of material has the following defects: environmental safety of forma...
