Description
Technical field
The present invention relates to the modified high-molecular field of new, be specifically related to a kind of high-performance reinforced nylon.This material can be widely used in the fields such as automobile, instrument, machinery, weaving, as making component and the employed material of structural part.
Background technology
Polyamide (PA) is commonly called as nylon, and its amide group has polarity, can form hydrogen bond, so mechanical property is outstanding, has shock resistance, is tough and tensile relatively engineering plastics.The characteristics of this material are: 1, degree of crystallinity height, and fusing point is obvious, and surface hardness is big, and is wear-resistant, and frictional coefficient is little, and self lubricity and noise reduction are arranged.2, low-temperature performance is fine, and certain thermotolerance is arranged.3, nontoxic, odorless, nothing are gone rotten, and self-extinguishing is arranged, good weatherability, but dyeability is poor.4, chemical stability is good, sea water resistance, anti-solvent, oil resistant, but not acidproof.5, electrical insulating property is good, but is subject to Temperature Influence.6, its water-absorbent is big, moisture effects dimensional stability and electrical property.Because its excellent performance so nylon application in industry is made is very extensive, as in fields such as automobile, instrument, machinery, weaving, adopts this material as component and structural part mostly.But its suction is big, deficiencies such as poor dimensional stability have limited its wider effect again, can reduce water-intake rate by the filling enhancing modified agent, guarantee under hot and humid condition, to work, simultaneously more can increase rigidity, reduce high temperature creep, shrinking percentage, improve dimensional stability, shock strength, wear resistance and flame retardant resistance.
General reinforced modifier mainly is exactly to add glass fibre, and high more its mechanical property of glass fibre addition (impact, stretching, flexural strength are big) is good more.External its glass fibre can add 50% to owing to advanced technology, and its product performance are excellent especially, the intensity height, and excellent wear resistance can be applicable to special purpose, as makes some structural parts (high pressure control cabinet switch etc.).Domestic present routine techniques glass fibre addition generally can only add 30% to, how will cause the fusion of glass fibre and resin bad again, and the surface floating fiber phenomenon is serious, and is mobile poor, appearance poor etc.
Summary of the invention
The invention provides a kind of high-performance reinforced nylon, its objective is that will solve present domestic routine techniques causes the low excessively problem of glass fibre addition.Thereby the product performance that make are reached fully and surpass external like product, alternative import.
For achieving the above object, the technical solution used in the present invention is: a kind of high-performance reinforced nylon, and composition of raw materials is:
Major ingredient:
(1), nylon 66 (PA66) 35～65 parts by weight;
(2), nylon 6 (PA6) 5 parts by weight;
Auxiliary material:
(1), compatilizer
Silicone 0.6～1.0 parts by weight;
(2), lubricant
Ethylene bis stearic acid amide (EBS) 0.4～0.6 parts by weight;
(3), oxidation inhibitor
Antioxidant 1010 0.2 parts by weight;
Oxidation inhibitor 168 0.2 parts by weight;
(4), reinforced modifier
Glass fibre 30～60 parts by weight.
The preparation method is as follows:
(1), main ingredient mixes
Major ingredient is mixed stirring with compatilizer, lubricant, oxidation inhibitor, reinforced modifier, each component fully is uniformly dispersed;
(2), melt extrude
The material that mixes is added in the twin screw extruder, melt extruding simultaneously, introduce glass fibre and melt extrude, melt extrude temperature 240～260 ℃ of scopes;
(3), granulation and aftertreatment
The material granulation and the aftertreatment of extruding got finished product.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " EBS " is the trade(brand)name of lubricant-ethylene bis stearic acid amide.Described antioxidant 1010 and oxidation inhibitor 168 are trade(brand)name and trade names.
2, in the such scheme, during described (1) step main ingredient mixes, adopt agitator under the high-speed condition more than the 1000 commentaries on classics/per minutes, to mix stirring, better effects if like this.
3, in the such scheme, described aftertreatment comprises cooling, air-dry, pelletizing, sieves, crosses magnetic, flow package.
The present invention is through experimental study repeatedly, finally search out a kind of special compatilizer-silicone, thereby solved the low excessively problem of glass fibre addition in nylon material preferably, improved the consistency between inorganics glass fibre and the organism resin, can make the glass fibre addition reach 50%, even 60%, its product good combination property, surface do not have floating fine phenomenon, and products appearance is good, good flame resistance, meet or exceed the requirement of external like product fully, can substitute import, and price have only external import like product half less than, market outlook are good, have very strong competitive power.
Description of drawings
Accompanying drawing 1 is process flow sheet of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment: a kind of high-performance reinforced nylon, the total prescription of raw material is:
Major ingredient:
(1), nylon 66 (PA66) 35～65 parts by weight;
(2), nylon 6 (PA6) 5 parts by weight;
Auxiliary material:
(1), compatilizer
Silicone 0.6～1.0 parts by weight;
(2), lubricant
Ethylene bis stearic acid amide (EBS) 0.4～0.6 parts by weight;
(3), oxidation inhibitor
Antioxidant 1010 0.2 parts by weight;
Oxidation inhibitor 168 0.2 parts by weight;
(4), reinforced modifier
Glass fibre 30～60 parts by weight.
It mainly is to add the glass fibre of different content and the ratio of major ingredient nylon that present technique is used, its performance is along with the increase of glass fibre addition changes, but after arriving to a certain degree, some performance index increases and is not obvious, so optimum addition is advisable with 50%.The consumption of various auxiliary dosages, particularly compatilizer remains unchanged.
Be 0.8 parts by weight with compatilizer below, lubricant is 0.5 parts by weight, antioxidant 1010 is 0.2 parts by weight, and oxidation inhibitor 168 is that 0.2 parts by weight are that four kinds of proportioning examples that example provides between different content glass fibre and the major ingredient nylon are illustrated, and specifically sees the following form:
