Abstract

The invention discloses a straw plastic for producing geotechnical products and a production method for the same, relating to the technical field of plastic particle production, and particularly relating to the field of plastic particle production for geotechnical products. According to the invention, natural straw with a fineness of 300-350 meshes, talcum powder, kieselguhr, a high-molecular polymer and a plastic additive are mixed, and granulated via twin-screw extrusion, and the formed products can be used for producing the geotechnical products of blind ditches, drainage strips and the like; the normal performances can be kept in specific conditions, and the longest keeping time can achieve 180 days; after that, the original performances are gradually lost and disintegration is performed to form fragments. The straw plastic disclosed by the invention further has a low processing temperature, and can finish thermoplastic forming at about 140-160 DEG C. However, common thermoplastic plastics need processing temperatures of greater than 230 DEG C.

Description

A kind of straw plastic and production method thereof for the production of geotechnological product
Technical field
The present invention relates to the plastic pellet production technical field, especially for the plastic pellet production field of Earthwork Products.
Background technology
Along with the great development of plastics industry and the extensive application of plastics, the waste or used plastics problem is day by day serious.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, usually only does simple burning disposal, produces potential safety hazard in the time of contaminate environment.The present invention then processes for stalk new road is provided.
Geotechnique's product is necessary product for civil engineering construction, and its effect comprises draining, settlement prevention, prevent from coming down, prevent erosion etc.Some novel geotechnological equipment requirements is in usage period later complete failure and degraded or disintegration.The present invention can satisfy this requirement.
Summary of the invention
The object of the invention is to invent a kind of straw plastic for the production of geotechnological product, to reduce the use of non-degradable plastics, slows down oil crisis, harmless treatment countryside wastes stalk, and satisfy performance requriements and the service requirements of specific earth working material.
The present invention is comprised of following raw material: natural straw, talcum powder, diatomite, high molecular polymer, additives for plastics.Described natural straw, talcum powder, diatomite, high molecular polymer, additives for plastics account for respectively 43～45%, 4～6%, 4～6%, 39～45%, 4～5% of raw material total mass.
High molecular polymer of the present invention is one or more in the plastics such as high density polyethylene(HDPE), Low Density Polyethylene, linear polyethylene, polypropylene.
Additives for plastics of the present invention is titanate coupling agent, stearic acid, maleic anhydride grafted polyethylene wax, maleic anhydride inoculated polypropylene.Described titanate coupling agent, stearic acid, maleic anhydride grafted polyethylene wax, maleic anhydride inoculated polypropylene account for respectively 0.3～0.5%, 0.7～1%, 2.5～3%, 0.5～1% of raw material total mass.
The product that the present invention forms can keep normal performance under given conditions for the production of geotechnological products such as french drain, drainage belts, the longlyest reaches 180 days, occurs afterwards to lose gradually original performance and disintegration occurs, and forms fragment.The present invention also has lower processing temperature, can finish thermoplastic shaping about 140～160 ℃.Common thermoplastics then needs the processing temperature more than 230 ℃.
The present invention has good mechanical strength and good processing characteristics, and can reduce the use of petroleum-based plastics.
Another purpose of the present invention provides the production method for the production of the straw plastic of geotechnological product:
Be after 300～350 purpose natural straws, talcum powder, diatomite, high molecular polymer, additives for plastics mix, through double-screw extruding pelletizing with fineness; When feeding intake, natural straw, talcum powder, diatomite, high molecular polymer, additives for plastics account for respectively 43～45%, 4～6%, 4～6%, 39～45%, 4～5% of raw material total mass.
Raw material particle properties of the present invention is stable, and is convenient for production.
Embodiment
