Description

Wear-resisting Wood-like co-extruded ASA alloy material of high durable dumb light and preparation method thereof

Technical field

The present invention relates to plastic material fields, more particularly to the wear-resisting Wood-like co-extruded ASA alloy material of high durable dumb light And preparation method thereof.

Background technique

There are congenital disadvantage, short life is easy water suction in addition, takes off the materials such as the wooden green wood anticorrosive wood of traditional generation, heavy bamboo wood Color, the problems such as rotting, is mouldy become the easily-consumed products of numerous outdoor engineerings and scenic area and scenic spot, and two trienniums will be overhauled And maintenance.Wood plastics composite co-extrusion new material inherits the double dominant of plastics and plant fiber, not only waterproof, moisture-proof, anti-mildew, It is termite-proof, even more there is extra long life, zero formaldehyde is pollution-free, and it is nuisanceless, it can be recycled.There is good plasticity simultaneously, Colorful style personalized customization.Wood moulding does not crack, does not expand, indeformable speciality eliminates later period maintenance and maintenance cost again, Just naturally become the wooden green wood of ideal generation.The natural timber resource of China is increasingly reduced, the market demand of timber product It measures growing day by day.Huge market demand and technological breakthrough will necessarily constantly widen the market channel of Wood-plastic material.

Nowadays conservation culture and beautiful China Reconstructs have risen to national strategy, regenerated resources and circular economy at For social consensus, health environment-friendly theory is rooted in the hearts of the people.Under numerous drives favourable, it is quick-fried that domestic wood moulding industry will welcome a new wheel Hairdo increases.It is counted according to the environmental impact assessment project data of various regions, newly operation production capacity is up to more than 300 ten thousand to coming years China's wood moulding industry Ton, in prediction on such basis, China's wood moulding industry gross output value are expected to 60,000,000,000 yuan of thresholds of challenge.It is pushed away simultaneously in every policy advantage and government Under dynamic, wood moulding industry faucet will also continue to increase technological innovation and brand creation dynamics, and it is intelligent to promote manufacture.Further dropping While low product cost, the core competitiveness of product is promoted, seizes external high-end market share, pushes domestic wood plastics composite new Material market is popularized.

But existing wood plastics composite product is largely PE wood-plastic products in the market, under national environmental protection policy, produces this The enterprise of a little products all suffers from transition.The PVC/ASA product of existing minority imitation wood line, there is also imitation wood line lines is unintelligible, The bad disadvantage of wearability.

Chinese patent CN200810184740 discloses a kind of Wood-like co-extruded ASA modified material and preparation method thereof, Component mainly includes ASA bottom material and ASA line material, weight percent are as follows: ASA foundation is 50%-90%, and ASA line material is 10%-50%.The plastic-steel door and window of above-mentioned Wood-like co-extruded ASA modified material production, three-dimensional sense is strong, and wood grain is true to nature；It can be achieved with modeling Dai Mu saves the valuable forest reserves；Excellent weatherability has expanded the application and development of imitative wood grain profile, can be applied to room Inside and outside door and window, guardrail, decorative panel, baseboard and preparation of furniture etc..The patent woodiness touch is slightly weak, and wearability is poor.

Summary of the invention

Based on this, the present invention provides a kind of wear-resisting Wood-like co-extruded ASA alloy material of high durable dumb light and preparation method thereof, Wood-like co-extruded ASA alloy material lines of the present invention is naturally clear, and wearability, weather resistance are good, and glossiness is low.

The specific technical proposal is:

A kind of wear-resisting Wood-like co-extruded ASA alloy material of high durable dumb light, is prepared by wood grain bottom material and wood grain agent；

The wood grain agent is by including that the raw material of following mass percent is prepared:
