Abstract
The present invention relates to a hemp stalk core plastics composite material. Its composition contains 49-79% of hemp stalk, core, 19-49% of thermoplastic plastics and 2-4% of adjuvant. The hemp stalk core is the residue produced by decorticating hemp crop and stripping fibre from leaf of hemp crop, and the described adjuvant contains one kind of the following components or combination of several kinds of them; lubricating agent, plasticizer, UV-ray-resisting agent, antioxidant, filling agent, reinforcing agent, fire-retardant, anti-static agent, coupling agent and binding agent. Its production method includes the following steps: cutting hemp stalk core, drying, pulverizing to 20-300 meshes, placing the hemp stalk core powder into high-speed mixing machine, mixing it with plastics powder granules and adjuvant, homogenizing, mixing, extruding, cooing, solidifying and forming so as to obtain the invented hemp stalk core plastics composite material.
Description
Technical field
The present invention relates to a kind of matrix material, particularly a kind of straw core plastics composite.
Background technology
Crudefiber crop is the main economic crops of China's agricultural, and crudefiber crop has tawny daylily fiber crops, flax, bluish dogbane, jute, sisal hemp, hemp, and the fiber of its stem skin or leaf portion is also named fiber crops usually, can be used as the raw material of textile industry.China's flaxen fiber gross annual output amount reaches 250,000 tons, and straw core the like waste output reaches about 330,000 tons (crudefiber crop is peelled off the residuum general designation straw core behind the fiber of stem skin or leaf portion), is to act as a fuel to burn more than 70%, is that a kind of great wave is useless.
Summary of the invention
Waste straw core after the objective of the invention is the fiber of straw skin or leaf portion peelled off, turn waste into wealth and be used, be combined into straw core plastics composite with thermoplastics, make product miscellaneous applicable to industries such as life, building, chemical industry, environmental protection, transportations, be mould in Dai Mu, generation, for the material of a kind of excellent property of aluminium alloy.The present invention designs straw core plastics composite, it is characterized in that constituting: straw core 49%-79% by following constituent and weight percent, thermoplastics 19%-49%, auxiliary agent 2%-4%, described straw core is the residuum after crudefiber crop is peelled off the fiber of stem skin or leaf portion, and described auxiliary agent contains one or more combinations of following composition: lubricant, softening agent, anti UV agent, oxidation inhibitor, weighting agent, toughener, fire retardant, antistatic agent, coupling agent, tackiness agent.The production method of straw core plastics composite; it is characterized in that: be ground into the 20-300 order after the straw core chopping oven dry; straw core powder added in the high-speed mixer mix with plastic powder particle and auxiliary agent, homogenizing; it is mixing to enter mixing facilities again; squeeze out through casement; make the particle of straw core plastics composite by tablets press again or squeeze out through pattern,, make the section bar of straw core plastics composite through quenching, curing by mixing facilities.
Advantage of the present invention is to make full use of depleted straw core, turn waste into wealth, and the matrix material texture of making is good, and intensity is big, the distributing of no obnoxious flavour.
Below in conjunction with embodiment the present invention is elaborated:
Specific implementation method
The straw core of chopping, putting into dryer dries, putting into pulverizer then pulverizes, the fineness of pulverizing is the 20-300 order, again straw core powder is added in the high-speed mixer that (wherein auxiliary agent contains lubricant with plastic powder particle and auxiliary agent, softening agent, anti UV agent, oxidation inhibitor, weighting agent, toughener, fire retardant, antistatic agent, coupling agent, tackiness agent) mixes, through shearing, shunting, place-exchange, reach the mixing of different components, the homogenizing of differing molecular weight polymers, the homogenizing of temperature, enter fusion in the mixing facilities again, formed straw core plastics composite squeezes out through casement, is made the particle of straw core plastics composite again by tablets press; Or squeeze out through pattern by mixing facilities, through quenching, curing, make the section bar of straw core plastics composite.
