Abstract
The invention discloses an application of polyamide acting as a flow accelerant in improving the glossiness of a reinforced ASA composite. Through research, an unexpected finding is that after polyamide acting as the flow accelerant is added to the reinforced ASA composite, the fluidity of the reinforced ASA composite during fusion can be improved significantly, polyamide resin forms a skin layer in an injection molding process, and ASA and a glass fiber material form a core material, so a typical skin-core structure can effectively prevent glass fiber from leaking outside, the surface of an injection molding piece presents superior luster, and the application scope of the polyamide resin in the market is widened substantially.
Description
Technical field
The present invention relates to the new application of polyamide, more particularly to polyamide are improving enhancing ASA groups as flow improver additive
The purposes of compound glossiness.
Background technology
ASA（Acrylate rubber, acrylonitrile, styrol copolymer）With being easily worked, it is adapted to injection, extrusion molding, blowing
Etc. various forming methods, and with preferable comprehensive mechanical property, therefore it is widely used in packaging, article of everyday use, electronics electricity
The fields such as device, toy, instrument, transport and machine manufacture.But for the structural fabrication of some high strengths requirements, such as refrigerator
Catch, television frame and support base of television etc., common ASA is difficult to meet mechanical property and dimensionally stable requirement.It is logical
Mechanical performance is remarkably improved frequently with fiberglass reinforced ASA, improves heat resistance, while can be by reducing linear thermal expansion system
Number and molding shrinkage, and then improve its dimensional stability.
There is bloom effect appearance part to have visual aesthetic feeling on consumption market, can more cause the favor of consumer,
But there are problems that glass flow orientation in fiberglass reinforced product injection moulding process, and there is obvious glass fibre flow liner, cause note
Plastic surface has floating fibre leakage occur can affect Injection moulded part surface smoothness, greatly reduce surface gloss.And for outer
For seeing product, it is desirable to which product surface is smooth, smooth, not existing defects.But, can not meet more than existing fiberglass reinforced ASA
The appearance requirement of product, limits its application.
In the research that " floating fibre " phenomenon is eliminated, spraying is common place's science and engineering that incrustation is carried out to plastic
Skill.But spraying is present as environmental pollution, overall high cost, the long efficiency of production procedure are low, paint film is de- in transport and using existing
Fall probability；In addition, existing researcher is developed from equipment and material prescription improves glass fiber reinforced materials surface, such as patent CN
103483761 A report a kind of fiber reinforcement ABS materials and preparation method thereof, and subsequent forming technique is high-speed and high-temperature molding
Technology（RHCM）, obtain bloom fiber glass reinforced ABS product, but RHCM technical equipment input is big, high energy consumption, do not meet low-carbon (LC),
The environmental protection concept of energy-saving and emission-reduction；Patent CN101469107 B discloses a kind of excellent surface, high flowing glass fiber reinforcement PBT/
ABS composites, by adding, substantial amounts of lubricant improves surface effect and the B of patent CN 101864117 is reported and increased
Add small molecule plasticizer such as bisphenol-A in strong ABS systems double（Diphenyl phosphate）, increase system mobility and reduce glass and leak outside
Excellent surface is obtained, but these lubricants or phosphate compound equimolecular quantity are low, easily place and surface precipitation with product,
There is hidden danger of quality, while glossiness is still less than 80 °, improvement is still undesirable；The A of patent CN 103275454 is utilized
Coupling agent is anticipated glass microballoon and SAN is added in resin, improves the glossiness and intensity of ABS plastics.But due to glass
Microballon early stage activation processing complicated and time consumption, and reinforced effects can not show a candle to glass, application is limited.Therefore, how high energy consumption is being avoided
Spraying or high-speed and high-temperature forming technique under, obtain has good mechanical properties, high-dimensional stability and appearance glossiness high simultaneously
Fiberglass reinforced modified rubber ASA products, be industry facing and technical barrier urgently to be resolved hurrily.
