The method has the advantages of simple technology, low cost, and environmental protection.
Description
Technical field
The present invention relates to the building template technical field, specifically is a kind of plastic and wood shuttering and production method thereof.
Background technology
China is a lower country of forest cover ratio, and in order to protect forest resources and ecotope, therefore country takes to limit the measure of lumbering material, and advocates and use substitute materials for wood.In addition, Xinjiang is the first cotton growing area of China, has every year millions of cotton stalks to produce; Surplus only Xinjiang year just reaching ten with mulch film ten thousand tons, these waste materials will bring bigger harm to environment as not utilizing.
Summary of the invention
The purpose of this invention is to provide plastic and wood shuttering and production method thereof, plastic and wood shuttering of the present invention have light weight, intensity height, indeformable, cost is low, reusable, characteristics such as economic benefit is high, purposes is wide, is specially adapted to building template.Production method technology of the present invention is simple, with low cost, and the starting material wide material sources can be turned waste into wealth, and recyclable reusing helps environment protection.
One of the object of the invention is achieved in that a kind of plastic and wood shuttering, it is characterized in that being forming: 55～75 parts of wood powder, waste and old wooden slag and/or cotton stalk particles by the component preparation of following parts by weight proportioning and compacting, 15～30 parts of waste polyethylene plastics and/or polyvinyl resins, auxiliary agent is 1～3 part of a properties-correcting agent (can claim compatilizer again), ageing-resistant dose 1～3 part, 2～4 parts of tackifier; Its goods MOR 〉=45N/mm
2, shock strength 〉=35KJ/m
2, quiet modulus in elasticity in bending 〉=3 * 10
3N/mm
3, poach, freezing, kept dry intensity 〉=35N/mm
2
Above-mentioned properties-correcting agent can be stearic acid and/or chlorinatedpolyethylene, and ageing-resistant dose is titanium dioxide and/or titanium dioxide, and tackifier are woods dioctyl phthalate BOP.
Can be added with in the above-mentioned auxiliary agent: 2～4 parts of lubricants, 4～6 parts of fire retardants (being conventional known technology)
Above-mentioned lubricant can be paraffin.
Two the main technical schemes of the object of the invention is: a kind of production method of above-mentioned plastic and wood shuttering, it is characterized in that, carry out at first that raw material is prepared and pre-treatment: waste and old wood and cotton stalk are carried out granulation and waste plastics such as waste mulching film polyethylene that reclaim (household plastic, agriculture plastics all can) and/or polyvinyl resin are carried out granulation; Carry out batch mixes then, add auxiliary agents such as properties-correcting agent, ageing-resistant dose, tackifier, lubricant, fire retardant simultaneously; Last mold pressing: pressurization extends into shape just.
Preferably dry earlier after the above-mentioned raw materials granulation, and then batching.
Temperature is good with 80～120 ℃ during above-mentioned mold pressing, and pressure is that 0.6～1.2Mpa keeps 10 minutes at least for good.
After above-mentioned pressurization extends into just shape, can be again through overcooling, and finished product is made in the last cutting of setting.
Technique effect of the present invention is tangible: plastic and wood shuttering of the present invention have light weight, intensity height, indeformable, cost is low, reusable, be easy to characteristics such as dismounting, economic benefit height, purposes be wide, can be used for furniture material and conveying tray etc., be particularly useful for building template.Production method technology of the present invention is simply unique, and with low cost, the starting material wide material sources can be turned waste into wealth, and recyclable reusing helps environment protection.
Be described further below in conjunction with embodiment, but not as a limitation of the invention.
Embodiment
Embodiment of the invention component batching sees Table 1.
Technology is as follows:
1, carrying out raw material prepares and pre-treatment: waste and old wood and cotton stalk are carried out granulation and the waste plastics such as waste mulching film polyethylene that reclaim are carried out granulation;
2, with oven dry such as wood powder drying machine, hot air dryer, microwave dryers;
3, carry out batch mixes, add auxiliary agents such as properties-correcting agent, ageing-resistant dose, tackifier, lubricant, fire retardant simultaneously;
4, mold pressing: pressurization extends into shape just, and temperature is 80～120 ℃ during mold pressing, and pressure is that 0.6～1.2Mpa kept 10 minutes at least;
5, cooling;
6, the finished product template is made in cutting: length * wide * thick=1500mm * 900mm * 10～15mm.
Performance test result: all meet specified requirements such as acceptance index shown in the table 2.MOR is pressed 6.2.5. execution among the JB/T3026, quiet modulus in elasticity in bending is pressed 6.2.5. execution among the JB/T3026, shock strength is pressed GB13123 and is carried out, and poach, freezing, kept dry intensity press 6.2.8. execution among the JB/T3026, and size deviation: plate length, width permissible variation are ± 5mm.
The performance of building template of the present invention and other material building templates relatively sees Table 3.
