Abstract
The invention discloses a method for preparing wood plastic products from straws and recycled plastics. The wood plastic products are prepared from the following raw materials in parts by weight: 20 to 30 parts of recycled plastics, 50 to 60 parts of wheat straws, 9 to 25 parts of acetic acid, 2 to 10 parts of compatilizers, 0.5 to 1.5 parts of lubricating agents, 0.2 to 0.4 part of antioxidants, 0.1 to 0.15 part of ultraviolet light absorbers, 0.1 to 0.15 part of mildew preventives and 2 to 4 parts of pigments. The recycled plastics and the wheat straws are used as raw materials, so that the finished product sales price is reduced, the energy is saved, and the environment is protected; the acetic acid is used for soaking the wheat straw powder; then, the wheat straw powder is mixed with the recycled plastics; the compatilizers are added; the modification is sufficiently performed; the two kinds of materials are promoted to be mixed; the product rigidity and the product toughness are good; anti-impact performance, corrosion resistance, oxidization resistance, illumination resistance and long service life are realized; the wood plastic products prepared by the method are very suitable for being used for manufacturing wood plastic houses.
Description
Technical field
The present invention relates to a kind of method of resource recycling, more particularly, to a kind of wooden using straw and recycled plastic preparation
The method of molding product.
Background technology
In recent years, gradually deficient and " white pollution " of timber resources constantly deteriorates, and the protection of ecological environment is increasingly subject to
Arrive and pay attention to, the development of wood based panel is faced with severe tests, this provides wide market environment, due to wood for the development of wood-plastic board
Mould plate is a kind of novel environment friendly based plate made using wood plastic composite, not only has processing characteristics of timber and wooden
Sense, the also characteristic such as water-fast, anti-corrosion of plastics, based on environmental protection, fashion is attractive in appearance, finishing easily feature, wood-plastic board is gradually
Enter in outdoor park and the finishing in house, but, due to its cost of material, lead to production cost too high, substitute traditional timber,
Need environmental protection, the wood-plastic products of low cost.
Retrieval finds, has been reported and points out, is former using waste PVC or PE plastics and agricultural crop straw, sawdust, bamboo scraps etc.
Material, prepares low price, the report of high-performance Wood-plastic floor by processing, such as patent 201410803700.4, and one kind utilizes wheat
The method that careless straw produces Wood-plastic floor；Weight proportion：Waste and old PE aggregate 30～31%, wheat straw waste powder 62～65%, light are steady
Determine agent 0.6～1.5%, PE processing aid 0.7～1.2%, PE impact modifier 0.5～0.8%, titanium dioxide 0.8～1.2%,
Smart paraffin wax 0.4～0.6%, stearic acid 0.4～0.6%, dibutyl ester 0.2～0.4%, pigment 0.3%.This dispensing is only suitable for
Indoor use, when making wood moulding house, during as roof and materials for wall, can quickly fade and become fragile, service life does not reach
The requirement of building construction.
Content of the invention
In order to solve problem present in current techniques, it is an object of the invention to provide one kind makes full use of straw and recovery
Plastics preparation, there is low cost, corrosion-resistant, light shine, it is suitable for the wood-plastic products of assembling, and its production method.
For reaching above-mentioned purpose, the technology used in the present invention means are：A kind of wooden using straw and recycled plastic preparation
The method of molding product, raw material is made up of following weight portion：Recycled plastic 20～30, Wheat Straw 50～60, acetic acid 9～25, compatible
Agent 2～10, lubricant 0.5～1.5, antioxidant 0.2～0.4, UV absorbent 0.1～0.15, antifungus agent 0.1～0.15,
Pigment 2～4.
Further, the described method preparing wood-plastic products using straw and recycled plastic, comprises the steps：
First, Wheat Straw is pulverized, cross 60～80 mesh sieves, add acetic acid mix homogeneously, stand 3～7d, then dry for standby；
2nd, recycled plastic is broken into powder, the Wheat Straw powder after being processed with step one is mixed, add compatilizer to stir；
3rd, lubricant, antioxidant, UV absorbent, antifungus agent, pigment, stirring are added in the mixed material of step 2
Uniformly send into pelletize in comminutor afterwards；
4th, the material after step 3 pelletize is sent into extruder, setting extruder temperature is 145～210 DEG C, extrusion molding；
5th, the sheet material water-spraying control that step 4 is extruded.
The beneficial effects of the present invention is：With recycled plastic and Wheat Straw as raw material, reduce sale of finished goods price, energy-conservation
Environmental protection；Wheat Straw powder is soaked using acetic acid, then mix with recycled plastic, and add compatilizer, fully modified with promote two kinds
Material mixing, product rigidity and pliability are all good, and impact resistance is corrosion-resistant, antioxidation, anti-light photograph, and long service life is especially suitable
Close and manufacture wood moulding house.
