Said invented method material is an ideal substitute for wood product.

Description

A kind of method of utilizing plastic waste to prepare matrix material
The present invention relates to a kind of method of utilizing plastic waste to prepare matrix material, particularly a kind of materials such as various thermoplastic waste plastics and vegetable fibre, tackiness agent that utilize prepare the method for matrix material by common physics and chemical process.
Before the present invention makes, publication number is that the Chinese patent of CN1066642A discloses a kind of " composite wood-plastics material and preparation technology thereof ", it is to adopt to get rubble earlier, slag is pulverized, get junk cleanings such as cotton wool vegetation again, bleaching, oven dry, pulverize the back as filler, then, use waste rubber, the plastic waste granulation is prepared burden as tackiness agent, add part industrial chemicals and various resin again, in proportion that batch mixes is even, be warmed to 60~100 ℃ and become the dough shape, under 120~180 ℃ temperature condition, send compression moulding in the mould again to, become moulding product after the depanning.Because the main raw material that above-mentioned composite wood-plastics material adopts is rubble, slag and waste rubber etc., it all not thermoplastic material, though through pulverizing, add processing such as tackiness agent, but the requirement of the plastics of its granularity, gluing combination degree obviously can not reach technological formings such as general employing is extruded, injection, therefore, can only be processed into compression moulding in mould again behind the dough shape, like this, be restricted with regard to the mode that makes moulding, can't process the product of technological formings such as employing is extruded, injection.
The objective of the invention is to overcome the defective that above-mentioned prior art exists, provide a kind of thermoplastic waste plastic of utilization to be main raw material, can adopt multiple molding mode to prepare the method for composite finished product.
The present invention is realized by the enforcement of following technical scheme: use organism as main raw material, plant cellulose, inorganics are as stopping composition, add auxiliary materials such as tackiness agent, lubricant, coupling agent, stir through mixing, the post-treatment of heating becomes matrix material, it is characterized in that: described organism is the thermoplastic waste plastic; The procedure of processing of matrix material is:
(1) thermoplastic waste plastic after will cleaning, drying, pulverize by 100% as raw material, add 10~30% vegetable fibre stopping composition, add 3~5% bonding resinoid again, 5~10% stone flour, 0.5~2% titanate coupling agent, 1~3% auxiliary materials such as lubricant;
(2) above-mentioned thermoplastic waste plastic's raw material, stopping composition and auxiliary material etc. are joined simultaneously mix in the high speed agitator, its stirring velocity is controlled at 900~1200 rev/mins, after the heat that self is produced during by stirring reaches 105~125 ℃, restir 3~6 minutes, being processed into diameter is the oblate particulate state master batch of 3~6mm, its core is the thermoplastic waste plastic, and other material cladding outside;
(3) with above-mentioned oblate particulate state master batch as raw material, press thermoplastic plastics shaping processing requirement processing, make composite finished product.
Described thermoplastic plastics shaping technology is a kind of in extrusion moulding, injection molding, the die cast.
Described thermoplastic waste plastic is one or more in the materials such as PE, PP, PS, ABS.
Described bonding resinoid is one or more among EEA, EVA, SBS, MBS, 1C7A, the 1F7B.
The present invention compared with prior art, owing to adopt with high-speed stirring after the raw material pulverizing, utilize the high temperature that himself produces that the thermoplastic waste plastic is processed into particulate state, therefore, have that raw material is heated evenly, particle is small, strong bonding property, be applicable to extrude, moulding process such as injection, die casting is processed into various composite products.
Simultaneously, adopt the prepared composite product of the technology of the present invention, the various characteristics that had both possessed timber, can saw, can dig, can follow closely, can bore, but possess various characteristicses such as plastic plasticity, toughness and binding property again, and fire-retardant, insulation, waterproof, protection against the tide, anticorrosion, mothproof, can be according to purposes, make resistance to compression, bending resistance, anti-aging, anti-impact, do not shrink, indeformable product, so it can be widely used in fields such as building materials, seawall timber, furniture, packing, pallet, decoration decorative materials.
Also because the present invention is a main raw material with the waste plastic in industrial and agricultural production and the life, and the alternative woodwork of the product that is processed into, therefore, to eliminating white pollution, the protection environment is saved timber, protects forest resources, and is significant.
Below in conjunction with embodiment technical scheme of the present invention is further elaborated.
