Toughening wood-plastic composite

Abstract

The invention discloses a toughening wood-plastic composite. The toughening wood-plastic composite comprises the following components in parts by weight: 40-65 parts of high-density polyethylene (HDPE), 35-45 parts of straw, 5-8 parts of polyethene, 3.5-4.5 parts of polyphenylenoxide, 2-3 parts of benzoin, 4-6 parts of methylphenyl polyborosiloxane, 2.0-2.5 parts of tetra-n-propylzirconate, 5.5-7.5 parts of asbestos, 5-7 parts of walnut shell powder, 8-10 parts of camphorwood powder, 6-8 parts of ginkgo leaves, 6-8 parts of aralia echinocaulis powder, 0.1-0.2 part of agalloch powder, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of lauryl sulfate, 4-6 parts of a toughening additive, 0.1-0.2 part of terpineol and 1-3 parts of white glue. The wood-plastic composite provided by the invention can continuously give out delicate fragrance. Boards have good intensity, and particularly have the characteristics of being flame-resistant, anticorrosive and moldproof, can be used indoors and outdoors, can resist ageing, are free from cracking or deforming, and have high tenacity.

Description

technical field [0001] The invention belongs to the technical field of plastic-wood material production, in particular to a toughened wood-plastic composite material. Background technique [0002] Building materials refer to the general term for various materials used in the field of construction and civil engineering, referred to as "building materials". Building materials in a narrow sense refer to materials used in civil engineering, such as steel, wood, glass, cement, paint, etc. Cement, steel and wood are usually called the three major materials of general construction engineering. Building materials in a broad sense also include materials used in construction equipment, such as wires and water pipes. "Building materials" in the discipline of architecture refers to the discipline that studies the physical and chemical properties of different building materials.

Problems solved by technology

The performance of existing WPC products is still not ideal, and there are still some defects, such as the texture uniformity, density, water absorption and other parameters of WPC panels still need to be further improved

Moreover, the variety of existing plastic wood materials is relatively single, and the space for users to choose according to their own preferences is too small.
