Abstract

The invention discloses a preparation method for a flame-retardant wood-plastic product. The flame-retardant wood-plastic product consists of the following raw materials in parts by weight: 10-20 parts of HDPE, 20-40 parts of wood powder, 4-5 parts of acetic acid, 1-3 parts of a compatilizer, 2-4 parts of a lubricant, 0.4-0.8 part of an anti-oxidant, 0.3-0.5 part of an ultraviolet light absorber, 0.4-0.6 part of a mildew preventive, 1.0-2.0 parts of red phosphorus, 8-12 parts of magnesium hydroxide, 25-35 parts of aluminum hydroxide and 2-4 parts of phosphate. According to the preparation method disclosed by the invention, wood powder is soaked in acetic acid, and then is mixed with HDPE; the compatilizer is added, and the compatilizer and the mixture are promoted to be mixed through sufficient modification; magnesium hydroxide, aluminum hydroxide, red phosphorus and phosphate are synchronized through organic and inorganic flame resistance, so that the flame resistance effect is ensured; moreover, aluminum hydroxide and magnesium hydroxide are added, so that rigidity and flexibility of products are improved; and a finally prepared board is resistant to impact, corrosion, oxidization and illumination, is flame-resistant, is long in service life, and is especially suitable for manufacturing a wood-plastic house.

Description

A kind of preparation method of flame-retardant wood-plastic product

Technical field

The present invention relates to a kind of production method of wood-plastic products, more particularly to a kind of preparation method of flame-retardant wood-plastic product.

Background technology

In recent years, gradually deficient and " white pollution " of timber resources constantly deteriorates, and the protection of ecological environment is increasingly received To attention, the development of wood based panel is faced with severe tests, and this provides wide market environment for the development of wood-plastic board, due to wood Mould plate is the not only processing characteristics with timber and wooden using a kind of novel environment friendly based plate made by wood plastic composite Sense, the also characteristic such as the water-fast of plastics, anti-corrosion, based on environmental protection, fashion is attractive in appearance, fit up convenient the characteristics of, wood-plastic board is gradually Into in the finishing in outdoor park and house, but, existing wood-plastic products are problematic in that on fire protection flame retarding.

The content of the invention

In order to solve problem present in current techniques, it is an object of the invention to provide a kind of preparation of flame-retardant wood-plastic product Method.

To reach above-mentioned purpose, the technology used in the present invention means are:A kind of preparation method of flame-retardant wood-plastic product, it is former Material is made up of following weight portion:HDPE 10~20, wood powder 20~40, acetic acid 4~5, compatilizer 1~3, lubricant 2~4, antioxygen Agent 0.4~0.8, UV absorbent 0.3~0.5, antifungus agent 0.4~0.6, red phosphorus 1.0~2.0, magnesium hydroxide 8~12, hydrogen Aluminium oxide 25~35, phosphate ester 2~4.

Further, the preparation method of the flame-retardant wood-plastic product, comprises the steps:

First, wood powder is crossed into 60~80 mesh sieves, adds acetic acid mix homogeneously, stand 10~20h, then dry for standby;

2nd, the wood powder after processed HDPE with step one mixes, and adds compatilizer to stir;

3rd, addition lubricant, antioxidant, UV absorbent, antifungus agent, red phosphorus, hydrogen-oxygen in the mixed material of step 2 Change magnesium, aluminium hydroxide, phosphate ester, after stirring, send into pelletize in comminutor;

4th, the material after step 3 pelletize is sent into into extruder, it is 145~210 DEG C to arrange extruder temperature, extrusion molding;

5th, the sheet material water-spraying control that step 4 is extruded.

The beneficial effects of the present invention is:Wood powder is soaked using acetic acid, is then mixed with HDPE, and is added compatilizer, fill Divide modified and promote bi-material to mix, magnesium hydroxide, aluminium hydroxide, red phosphorus, phosphate ester are with the fire-retardant synchronization of organic-inorganic, it is ensured that Flame retardant effect, and the addition of aluminium hydroxide, magnesium hydroxide improves product rigidity and pliability, the final sheet material anti-impact for preparing Hit, corrosion-resistant, antioxidation, anti-light photograph, fire-retardant, long service life, be particularly suitable for manufacturing wood moulding house.

Specific embodiment
