Abstract
The invention relates to an additive for injection molding white polyamide (PA) plastic and a method for injection molding a white polyamide (PA) plastic piece. The additive comprises one kind or multiple kinds of siloxane polymer resin and modified siloxane polymer resin. By weight, the siloxane polymer resin or/and the modified siloxane polymer resin is 2%o-5%o, and the balance is the white PA plastic. Due to the fact that the siloxane polymer resin or/and the modified siloxane polymer resin are added in the white PA plastic, when the white PA is moulded in an injection mode and demoulded, the phenomenon of mold sticking cannot occur. Besides, viscosity of plastisol of the white PA plastic can be also improved, and surface gloss and abrasive resistance of the PA plastic piece are improved.
Description
[technical field]
The invention belongs to chemical technology field, relate to the method for injection moulding white PA additives for plastics and injection moulding white PA plastic component.
[background technology]
PA is that the chemistry of polymeric amide (Polyamide) is called for short.Polymeric amide is for being the translucent or oyster white crystalline resin of toughness horn shape, is generally 1.5-3 ten thousand as the polyamide molecular weight of engineering plastics.Polymeric amide has very high physical strength, and softening temperature is high, and is heat-resisting, and frictional coefficient is low, wear-resistant, self lubricity, and shock absorption and noise reduction, oil resistant, weak acid resistant, alkaline-resisting and common solvent, electrical insulating property is good, and self-extinguishing is arranged, and is nontoxic, odorless, good weatherability, dyeability is poor.Shortcoming is that water-absorbent is large, affects dimensional stability and electrical property, and fiber reinforcement can reduce the resin water-intake rate, can work under high temperature, high humidity.
Characteristics due to the strong polarity of PA, so water absorbability is strong, poor dimensional stability, but can improve by modification, the ultraviolet auxiliary agents of absorption such as carbon black have been added in PA, the self lubricity of PA is strengthened greatly, do not add the PA of any auxiliary agent the phenomenon of sticking to mould can occur because of the stronger reason of its water absorbability, the phenomenon of sticking to mould can not occur for the black PA plastics that add black agglomerate.Be directed to the problem of present white PA plastics sticking to mould, generally smear lubricant on the mold cavity of injection moulding is green in the industry, perhaps the chemical assistant by adding other and white PA mix white PA plastics are carried out chemistry or physically modified, but these chemical assistants or addition means are complicated, its cost is higher, bring new defective physically can for the PA plastics, as colour-change, strength degradation etc.So also can not find out the additive of most suitable white PA plastics at present, can enough very low costs be improved by self lubricity and other performances of white PA plastics.
[summary of the invention]

Described siloxane polymerization resin is one or more in polymethyl siloxane, polydimethylsiloxane, poly-trimethicone, and described modified siloxane fluoropolymer resin is one or more in amino modified polysiloxane, epoxy polysiloxane and phenyl modified polysiloxane.
The polymerization degree of described siloxane polymerization resin and these two polymkeric substance of modified polyorganosiloxane fluoropolymer resin is 1～1000.
More excellent, the polymerization degree of two polymkeric substance is 3～100.
The present invention separately provides a kind of method of injection moulding white PA plastic component, it is characterized in that, the method comprises:
In weight part, add 2～5 parts of additives in 995～998 parts of white PA plastics to be processed, mix;
The mixture of white PA plastics and additive is dropped in the barrel of injection moulding machine;
Injection moulding machine is with white PA plastics and additive heating and melting and be expelled to injection moulding in the die cavity of mould after stirring.
The method further comprises:
The mixture of white PA plastics and additive is dropped into the opening for feed of screw extrusion press, the plastic master batch that screw extrusion press is extruded is put into the injection moulding machine injection moulding.
This additive comprises one or more of siloxane polymer resin and modified siloxane fluoropolymer resin.
Described siloxane polymerization resin is one or more in polymethyl siloxane, polydimethylsiloxane, poly-trimethicone, and described modified siloxane fluoropolymer resin is one or more in amino modified polysiloxane, epoxy polysiloxane, phenyl modified polysiloxane.
