Abstract
A kind of degradable plastic film and its production method, are related to plastics extrusion blow molding technical field, and length is mixed with plastics, plastic additive after drying for 1.5-2.0mm agricultural crop straw chip；Plastics, natural plant fibre, plastic additive are respectively 60-70 parts, 20-30 parts and 5-10 parts, through double screw extruder extruding pelletization；Particle is added in single screw extrusion machine and carries out blown film.The film uniform state of formation is stable, the common plastics polybags such as polypropylene can be replaced, with good surface smoothness, intensity height, good toughness, comfortable feel.The present invention can reduce the cost of degradation plastic, degradation cycle up to 180 days.
Description
Technical field
The present invention relates to the granulating technique field of plastics, blown film techniques field, the processing recovery process technical field of agricultural waste material is directed to.
Background technology
With the development of plastics industry, the application of plastics in daily life is extensive all the more, and usage amount is huge all the more.Because these plastics are generally non-degradable material, while bulk petroleum resource is consumed, the discarded object of production will also result in huge pollution.
Agricultural crop straw refers to the discarded object in agricultural production process, generally does burning disposal.The method not only wastes agricultural crop straw and is potentially worth, and can also cause air pollution.The smog meeting block vision produced in burning process, causes potential safety hazard, flame during burning is also possible to trigger fire.
The content of the invention
It is an object of the invention to invent a kind of crops plastics, with reduce because abandon non-degradable plastics and caused by environmental pollution, and by collect agricultural crop straw be used.
The present invention is made up of degradation plastic, agricultural crop straw and plastic additive, and the degradation plastic, agricultural crop straw, plastic additive are respectively 60-70 parts, 20-30 parts and 5-10 parts.
The degradation plastic is PLA (PLA).
The agricultural crop straw corn stalk.
The plastic additive is the one or more in wood moulding coupling agent, Aluminate/phosphate composite coupler, calcium stearate, white oil.
The processing temperature of the present invention is low, it is only necessary to which 140-160 DEG C i.e. plastic.The heat resisting temperature of the present invention fully meets general use demand up to 80-100 DEG C.The present invention can replace the common plastics such as polypropylene, and polybag is prepared by blowfilm shaping method.The color of natural timber is showed for the plastic products that raw material are produced by the present invention, surface has the texture of string, and with good surface smoothness, intensity height, good toughness, comfortable feel.It is degradation material because the present invention is raw materials used, therefore, degradation cycle of the present invention up to 180 days is a kind of material of environmental protection.
It is a further object of the present invention to provide the production method of crops plastic sheeting.
Length is mixed with plastics, plastic additive after drying for 1.5-2.0mm agricultural crop straw chip, plastics, natural plant fibre, plastic additive are respectively 60-70 parts, 20-30 parts and 5-10 parts.Through double screw extruder.Particle is added in single screw extrusion machine and carries out blown film.
The membrane product being made up of above-mentioned plastic pellet, also with good gas permeability, is particularly suitable for use in the occasion of permeable watertight in addition to the property for possessing common plastic film, such as preservative film, paper diaper inner membrance.The product produced by above-mentioned plastic pellet is 180 days under composting conditionses, and degradation rate reaches more than 95%.
The convenient production of the present invention, the film of formation is uniform, in stable condition, it is easy to further production and processing, and without being transformed through row existing equipment.Present invention also reduces the cost of degradation plastic, while improving the mechanical property of degradation plastic, condition is provided for the extensive use of degradation plastic.
