Abstract
The invention relates to a nano intensified-nylon-6 composite, which is prepared by blending the following major materials according to different percentages, melting and extruding the materials under the temperature of 215 DEG C to 250 DEG C: 50 percent to 70 percent of nylon slices, 25 percent to 30 percent of glass fiber, 0.05 percent to 0.1 percent of antioxidant I, 0.05 percent to 0.1 percent of antioxidant II, 1 percent to 1.5 percent of lubricant, 0.5 percent to 1 percent of nano material and 0.25 percent to 1 percent of coupling agent; the invention needs no compatilizer and tackifier, greatly reduces the cost, solves the problem that the glass fiber of the engineering plastics is exposed during the injection molding process, improves the appearance quality of the products and enhances the physical indexes of the products to a certain degree, thus changing the situation that some domestic manufacturers depend on the imported nylon. The composite of the invention can be used for the automobile and electromechanical industry fields, can be acted as a thin-walled complicated structural product due to the high rigidness, and is an environment protective product that can substitute the present halogenous fire retardants due to the fire resistance, which is energy conservative and environment protective and is an ideal product for the current engineering plastic modification industry.
Description
Technical field:
The present invention relates to the engineering plastics field, relate in particular to a kind of nanometer type reinforced nylon 6 dragon 6 composition and method of making the sames.
Background technology
The motor car engine circumferential component mainly is heating and vibrating mass, therefore need used material need have very high over-all properties, but glass fibre is because dispersed and mobile poor, there are tangible weld mark and current mark in its injection-molded item surface, even the phenomenon that has glass fibre to expose, had a strong impact on the outward appearance of goods.Nylon has high strength, wear-resisting, anti-molten, advantage such as self lubricity good and the use temperature scope is wide, and chemical-resistant resistance and oil-proofness are outstanding, are most widely used kinds in the five large-engineering plastics, now are widely used in various electronic electric equipments and household appliances.
Summary of the invention:
The objective of the invention is characteristics at existing widely used nylon plastic, a kind of novel nano type Reinforced Nylon 6 composition and method of making the sames are provided, not only solved the engineering plastics problem that glass fibre exposes in injection moulding process, improve the visual appearance of product, the product physical index is all increased, particularly the general reinforced plastics of bending strength ratio doubles abovely, makes product improve new class, has also changed the general layout of more domestic manufacturer's dependence on import.
Technical scheme of the present invention realizes with following method:
A kind of nanometer type reinforced nylon 6 dragon 6 compositions, it melt extrudes and gets by the blend of following main materials precentagewise and in 215-250 ℃:
Nylon chips 50%-70%
Glass fibre 25%-30%
Oxidation inhibitor one 0.05%-0.1%
Oxidation inhibitor two 0.05%-0.1%

Prepare nanometer type reinforced nylon 6 dragon 6 method for compositions of the present invention, its key step is:
The first step, oxidation inhibitor one, oxidation inhibitor two and lubricant are added mixing machine in proportion mix, the gained mixture is standby;
Second the step, with the nylon chips drying;
The 3rd goes on foot, dried nylon chips, the first step gained mixture, nano material and coupling agent is mixed according to previously described ratio adding mixing machine.Mixture adds in the forcing machine, glass fibre adds forcing machine by the forcing machine spout, melt extrudes in 215-250 ℃;
The 4th step, extrudate are by water-cooled or air-cooled the cooling;
The 5th step, to cooling off back products obtained therefrom pelletizing, classification, packaging final prod;
Described drying temperature is 90-110 ℃, and be no more than 6 hours time of drying;
The mixing machine mixing time is at least 1 minute in the described the first step;
Positively effect of the present invention is:
Nanometer type reinforced nylon 6 dragon 6 compositions of the present invention do not have compatilizer, tackifier, cost reduces greatly, solved the engineering plastics problem that glass fibre exposes in injection moulding process simultaneously, improve the visual appearance of product, the product physical index all increases, particularly the general reinforced plastics of bending strength ratio doubles abovely, makes product improve new class, has changed the general layout of more domestic manufacturer's dependence on import.The present invention utilizes nano plastic thermotolerance and good mechanical performance, can be used for automobile and mechanotronics field, can be used as automobile component, because the rigidity height can also be used as the thin wall complex structure product, reduce weight and cost, has flame retardant resistance, be the environmentfriendly products that substitute halogen containing flame-retardant at present, this product has energy-saving and environmental protection, is the ideal product of current engineering plastic modification industry.
