Abstract
The invention discloses an application of polyester as a flow promoter in improving glossiness of a reinforced ABS composition. According to the invention, an unexpected research discovery shows that the polyester is used as the flow promoter and added into the reinforced ABS composition, and can significantly improve the fluidity of the reinforced ABS composition during melting, so polyester resin forms a cortex in the process of injection molding, and ABS and a glass fiber material form a core material; thus, a typical cortex-core structure can effectively prevent glass fiber from outleakage, and enables the surface of an injection-molded product to show high glossiness, thereby greatly broadening the application scope of the polyester resin in the market.
Description
Technical field
The present invention relates to the new application of polyester, more particularly to polyester are improving reinforced ABS compositionss as flow improver additive
The purposes of glossiness.
Background technology
ABS（The copolymer of acrylonitrile, butadiene and styrene composition）, with being easily worked, be adapted to injection, extrusion molding, blow
Various forming methods such as modeling, and there is preferable comprehensive mechanical property, therefore it is widely used in packaging, article of everyday use, electronics
The fields such as electrical equipment, toy, instrument, transport and machine manufacture.But for the structural fabrication of some high strengths requirements, such as ice
Chamber door handle, television frame and support base of television etc., ABS is difficult to meet mechanical property and dimensionally stable requirement.Generally
Mechanical performance is remarkably improved using fiber glass reinforced ABS, improves heat resistance, while can be by reducing thermal linear expansion coefficient
And molding shrinkage, and then improve its dimensional stability.
There is on consumption market bloom effect appearance part to have visual aesthetic feeling, can more cause the favor of consumer,
But in fiberglass reinforced product injection moulding process, there is glass flow orientation, 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 fiber glass reinforced ABS
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 be 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, improve surface effect and patent CN by adding substantial amounts of lubricant in single polyester system PBT
101864117 B are reported and are added small molecule plasticizer such as bisphenol-A pair in reinforced ABS system（Diphenyl phosphate）, increase body
It is that mobility reduces glass leakage to obtain excellent surface, but these lubricants or phosphate compound equimolecular quantity is low, hold
Easily place and surface precipitation with product, there is hidden danger of quality, while glossiness is still less than 80 °, improvement is still undesirable；
103275454 A of patent CN anticipates glass microballoon using coupling agent and adds SAN in resin, improves ABS plastics
Glossiness and intensity.But due to glass microballoon early stage activation processing complicated and time consumption, and reinforced effects can not show a candle to glass, and application is received
Limit.Therefore, how under the spraying or high-speed and high-temperature forming technique for avoiding high energy consumption, obtaining has good mechanical properties, height simultaneously
The high fiber glass reinforced ABS product of dimensional stability and appearance glossiness, is industry facing technical barrier urgently to be resolved hurrily.
