Abstract
The invention relates to a composition material formed by natural cellulose and synthetic resin or polylactic acid, and belongs to the technical field of synthetic materials. The composition material formed by the natural cellulose and the synthetic resin or polylactic acid comprises 10 to 90 weight percent of natural cellulose powder, 90 to 10 weight percent of resin and 0 to 5 weight percent of coupling agent, wherein the natural cellulose powder is straw, bagasse, sawdust or low value wood; the resin is any one of synthetic resin or polylactic acid; and the coupling agent is any one of silanes and titanate esters. The composition material has the advantages of low cost, high mechanical strength, low residue of harmful substances such as formaldehyde and melamine, and quickly natural degradation of cellulose in the composition under the action of microorganisms or physical and chemical factors.
Description
Technical field:
The present invention relates to a kind of composition material that forms by natural fiber matter and synthetic resins or poly(lactic acid), belong to the synthetic materials technical field.
Background technology:
Polyester articles such as at present a large amount of imitative porcelain tablewares, toy, wrapping material all adopt melamine resin or urea-formaldehyde resin or other resin materials that forms with trimeric cyanamide or urea, oxymethylene polymerization, these materials have advantages such as anti-certain high temperature, the better physical strength of tool, but also have formaldehyde or melamine residual, a large amount of fossil feedstock of consumption, be difficult to natural degradation, cost is than problems such as height; And occurring in nature exists the not high natural cellulose of stalk, wood chip or economic worth to belong to renewable resources in a large number, these cellulosics are with low cost, natural fiber mass-energy and synthetic resins, poly(lactic acid) and multiple action of coupling agents, the composition material that obtains has better toughness, physical strength, formability and heat-resistant quality.Fiber mass-energy in the composition that natural fiber matter and synthetic resins form is taken the lead in degrading by microorganism or various physical and chemical factor, causes the loose vesicular structure of remaining resin formation, is beneficial to the latter and decomposes fast or degraded.
Document CN1068391C " fibre blend of melmac fiber and natural fiber " is the natural macrofiber that adopts, and uses or do not use the melmac fiber of metallic coating, is used to make anti-flaming clothes or gloves etc.; CN101200581A " natural fibre reinforced to polylactic acid based resin combination " is natural bast long fiber equally, uses coupling agent, with heat-resistant quality and the physical strength of improving poly(lactic acid).
Summary of the invention:
The object of the present invention is to provide a kind of cost low, the physical strength height, residues of harmful substances such as formaldehyde or trimeric cyanamide are low, the composition material that is formed by natural fiber matter and synthetic resins or poly(lactic acid).
The present invention is in conjunction with the advantage of natural fiber matter and synthetic resins, poly(lactic acid), with the natural fiber matter pulverized as the filling of synthetic resins or poly(lactic acid), substitute, enhancement component, form composition material with synthetic resins or poly(lactic acid).
The component of the composition material that is formed by natural fiber matter and synthetic resins or poly(lactic acid) of the present invention comprises: the coupling agent of the natural fiber powder of 10-90% weight, the resin of 90-10% weight, 0-5% weight.Wherein: the natural cellulose powder is stalk, bagasse, wood chip or low value timber, obtains after washing, drying and dehydrating, pulverizing, the processing of screening link; The control sieve size is the 30-600 order; Resin is any of synthetic resins or poly(lactic acid); Coupling agent is any in silicane, the titanate ester.
The composition material that composition material of the present invention is formed by natural fiber matter and synthetic resins or poly(lactic acid) is with conventional synthetic or forming method preparation.
Residues of harmful substances such as composition material of the present invention has that cost is low, physical strength is high, formability is good, formaldehyde or trimeric cyanamide are low, the advantage that the cellulosic in the composition material can the rapid and natural degraded under microorganism or chemical factors effect.
