Description
Technical field
The invention belongs to wood plastic composite field, and in particular to one kind using waste or used plastics prepare wood plastic composite and
Its preparation method.
Background technology
Plastics and plastic products are that the production and life of the mankind brings huge contribution in the evolution of last 100 yearses
With unlimited convenience, but some plastic products go out of use after its life cycle terminates over time, severe contamination ring
Border, have become one it is increasingly serious the problem of.According to relevant measuring and calculating, the amount of waste or used plastics is 50% or so of plastics total output.
If these waste or used plastics can not be recycled in time, the huge wasting of resources is not only caused, it is often more important that cause great
Environmental pollution.Plastics-production depends on oil, and oil is that the resource formed was developed by up to a million years, with non-renewable property
Matter, therefore the using priciple of plastics is decrement, regeneration, recycling.The recyclings of waste or used plastics not still economic development
Need, the need for being also environmental protection.The rate of recovery of current China waste or used plastics only has 20% or so, and developed country then reaches
70% or so.Therefore, China needs to increase the recycling to waste or used plastics.
Wood plastic composite is rapidly developed because of its function admirable.Timber is used as composition important in wood plastic composite
Part, the demand of timber is also growing day by day.The forest reserves of China are limited, with China's expanding economy, the confession of timber
It should measure and reduce year by year, price rises year by year, the production cost of wood moulding manufacturing enterprise is also in increase.Wood plastic composite, not only may be used
The effective some performance deficiencies for solving homogenous material, and these wood plastic composites should in building, the extensive of engineering field
With, provide an effective way for the recycling of waste or used plastics, be also solve environmental issue, reduction white pollution it is effective
Mode.But waste or used plastics are more difficult to because containing more impurity, physical and chemical performance is poor with the mixing and molding of fiber.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of intensity is high, toughness is big, the profit with excellent machinability
Wood plastic composite is prepared with waste or used plastics.
Present invention also offers the preparation method that this prepares wood plastic composite using waste or used plastics.
The purpose of the present invention is achieved by the following technical solution：
One kind prepares wood plastic composite using waste or used plastics, is as made from the raw material of following parts by weight：Waste or used plastics 100
Part, modified 20-30 parts of poplar wadding, 1-3 parts of toughener, 1-2 parts of reinforcing agent, 0.5-1 parts of antioxidant, CaCO34-6 parts.
Described, modified Yang Xushi is as made from following methods：Poplar wadding will be dried to immerse in 2% sodium hydroxide solution,
26-30 DEG C of immersion 50min, is filtered, and 80 mesh sieves are crossed in drying after crushing, obtains alkali process poplar wadding；By alkali process poplar wadding and glycerine 26-
30 DEG C of mixing 10min, obtain modified poplar wadding.
Described, the weight ratio of alkali process poplar wadding and glycerine is 1：1.5-2.
Described, toughener is SBS and polytrifluorochloroethylene according to 1：0.3-
0.5 weight is than obtained.
Described, reinforcing agent is tungsten carbide powder and ethylenediamine tetra-acetic acid according to 1：1-2 weight is than obtained.
Described, waste or used plastics are the waste polyvinyl chloride by sorting granulation；The antioxidant be antioxidant 1076 or
Irgasfos 168.
A kind of utilization waste or used plastics prepare the preparation method of wood plastic composite, are as made from following steps：
1）By waste or used plastics and modified poplar wadding mixed at high speed 10min, rotating speed is 1200rpm；
2）Reinforcing agent is added into step 1）In the material mixed, toughener and antioxidant high-speed stirring are added when 75 DEG C of temperature
Mix；CaCO is added when temperature reaches 110 DEG C3, high-speed stirred, when continuing to be heated to 120 DEG C, stopping stirring；
3）By step 2）Material after processing is delivered in extruder, is heated to 145 DEG C, through mould shape, cooling, traction, scale,
Cutting, is made and prepares wood plastic composite using waste or used plastics.
Beneficial effects of the present invention：
1. present invention uses substantial amounts of waste or used plastics and modified poplar wadding, turn waste into wealth, that is, protect environment to save resource again,
Production cost is low；The wood plastic composite intensity of preparation is high, toughness is big, with excellent machinability, and easily reclaims, with notable
Economic and social benefit.
2. the present invention is wadded a quilt with cotton using modified poplar, the compatibility and dispersion effect with waste or used plastics, prepared wood are significantly improved
