Abstract
The invention discloses lightweight wood-plastic mixed granules containing straws and a production method thereof, and relates to the technical field of plastic raw material granules. After natural straws, cork powder, polypropylene and plastic aid are mixed, the mixture is extruded and granulated through double screws; the density of the formed granules can be 900kg/m<3>, and the raw materials or the wastes can be separated together with the polypropylene in a centrifugal separation system; and the mixed granules have low machining temperature, good mechanical strength and excellent machinability, and can be repeatedly machined and formed without changing the density. By the production method, the consumption of non-degradable petroleum-based plastic can be reduced, oil crisis is retarded, and an innocent treatment and a good purpose are provided for agricultural wastes; and the production method is favorable for saving resources and protecting the environment.
Description
Technical field
The present invention relates to the production technical field of plastic raw materials particle and goods thereof.
Background technology
Along with the great development of plastics industry and the extensive application of plastics, the waste or used plastics problem is serious day by day.Conventional plastic can't natural degradation after discarded and soil, underground water and air is caused severe contamination, and directly inefficiency is then got half the result with twice the effort in recovery.Resultant white pollution has become the problem in the puzzlement whole world, and environmental protection pressure is extremely huge.
Agricultural crop straw is the waste in the agricultural, owing to there is not better way, the depleted agricultural crop straw is only done simple burning disposal usually; Not only environment is caused serious pollution; Also can soil itself cause the disappearance of nutrition aspect, the meeting that also has causes fire, produces potential safety hazard.
Summary of the invention
The object of the invention is to invent a kind of light wood-plastic mixing pellet that contains stalk, to reduce the use of non-degradable plastics, slows down oil crisis, and proposes a kind of purposes of harmless treatment countryside wastes stalk.
The present invention is made up of natural stalk, dust cork, Vestolen PP 7052 and additives for plastics; Said natural stalk, dust cork, Vestolen PP 7052, additives for plastics account for 18～20%, 8～12%, 64～70%, 4～5.5% of raw material total mass respectively.
The density of said mixing pellet is 900 ~ 930 kilograms/meter
3
Natural stalk according to the invention is one or more in the agricultural waste materials such as rice straw, wheat straw waste.
Additives for plastics according to the invention is made up of titanate coupling agent, Triple Pressed Stearic Acid, ethylene bis stearic acid amide and white titanium pigment.Said titanate coupling agent, Triple Pressed Stearic Acid, ethylene bis stearic acid amide, white titanium pigment account for 0.3～0.5%, 0.7～1%, 2.5～3%, 0.5～1% of raw material total mass respectively.
The density of pellet of the present invention can be low to moderate 900kg/m
3, having the density identical with Vestolen PP 7052, its raw material or waste material can together be separated with Vestolen PP 7052 in centrifugal separation system.The present invention also has lower processing temperature, about 170 ~ 180 ℃, can accomplish thermoplastic shaping.Common thermoplastics then needs the processing temperature more than 230 ℃.The present invention also has good mechanical intensity and good processing characteristics, can repeat machine-shaping and does not change density.The present invention can reduce the use of non-degradable petroleum-based plastics, slows down oil crisis, for agricultural wastes propose a kind of good purposes of a kind of harmless treatment, is beneficial to and economizes on resources, protects environment.
Another object of the present invention provides the working method of the light wood-plastic mixing pellet that contains stalk:
With fineness is that the natural stalk of 100 ~ 150 purposes, fineness are after 600 ~ 800 purpose dust corks, Vestolen PP 7052 and additives for plastics mix, through double-screw extruding pelletizing; When feeding intake, natural stalk, dust cork, Vestolen PP 7052, additives for plastics account for 18～20%, 8～12%, 64～70%, 4～5.5% of raw material total mass respectively.
The present invention produces simply, rationally, and convenient, the granule performance of formation is stable.
Embodiment
One, granulation
With natural crushed stalk to 100～150 orders, subsequent use.
Dust cork is crushed to 600～800 orders, subsequent use.
Natural stalk, dust cork, Vestolen PP 7052 and the titanate coupling agent pulverized, Triple Pressed Stearic Acid, ethylene bis stearic acid amide, white titanium pigment is even with 8～20%, 8～12%, 64～70%, 0.3～0.5%, 0.7～1%, 2.5～3%, 0.5～1% the mixed that accounts for the raw material total mass respectively; Dewater through high temperature and to be placed in the twin-screw mixer forcing machine; Extruding pelletization under 150 ~ 165 ℃ of conditions; Both having obtained raw material particle of the present invention, is 900 ~ 930 kilograms/meter through its density of test
3
Two, use
The alternative general Vestolen PP 7052 of plastic pellet of the present invention is produced.Can the present invention be placed injection moulding machine, select 170 ~ 180 ℃ of injection temperatures, can injection moulding obtain different goods, to substitute all plastics according to different moulds.The present invention and reclaimed materials thereof are reusable, and density does not change.
