Abstract
The invention relates to organic polymer composite material, in particular to highly-polished ethylene glycol resistant composite reinforced nylon 66 and a process for producing the same. The highly-polished ethylene glycol resistant composite reinforced nylon 66 comprises the following components by weight percent: 50-70 percent of nylon 66, 25-35 percent of halogen-free alkali-free glass fiber, 0.1-3.0 percent of heat stabilizer, 0.2-1.5 percent of ethylene glycol resistant treating agent, 0.1-3.0 percent of glass fiber treating agent, 0.1-0.5 percent of nucleating agent, 1.0-2.5 percent of nylon-base high-pigment black masterbatch and 1.3-5.5 percent of other auxiliary agent. The highly-polished ethylene glycol resistant composite reinforced nylon 66 has highly-polished appearance and long-term heat, aging and ethylene glycol resisting characteristics in addition to the excellent mechanical properties, is convenient to produce and purchase, adopts the domestic raw materials, auxiliary materials and additives and meets all the environmental protection requirements, thereby being more competitive.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of highly-polished ethylene glycol resistant composite reinforced nylon 66 and preparation method thereof.
Background technology
Nylon 66 is polyamide resins, use one of maximum several engineering plastics at present, his amide group has polarity, in his structure, has well-set hydrogen bond, make that the fusing point of nylon 66 is higher, have good physical and mechanical property and wear resistance and self lubricity, these comprehensive characteristics are that other plastics are not available.But the heat-drawn wire of pure nylon 66 is lower, and water-absorbent is big, and shock strength is on the low side before the suction, suction back rigidity shortcoming such as decline to a great extent again, thus limited the application of nylon 66, and then dwindled downstream industry design engineer's selection leeway again.Therefore, launched nylon 66 is carried out composite modified research.And improve the comprehensive employed the most universal the most effective method of physical and mechanical property of nylon 66 material, adopt glass fiber reinforced nylon 66 exactly.But glass fiber reinforced nylon 66 is when significantly improving nylon 66 physical and mechanical properties, individual distinct disadvantage is arranged again, exactly because glass and nylon 66 two-phase interfaces are difficult for good combination, cause producing the glass emergence on the surface phenomenon at product surface easily, the said dew fibre of just common insider/floating fine, so just obviously reduced product surface smooth finish, make product surface coarse and grow dim, thereby limited the application of this starting material on the product that surface smoothness or aesthetic measure are had relatively high expectations.In addition, though nylon 66 self ageing resistance is fine, but owing to self exist water-intake rate higher, can absorb airborne moisture for a long time, thereby cause rerum natura to change, especially in the environment of long-term continuous high temperature high humidity, this shortcoming has become and can't accept, and must be improved significantly.
In the market, have only external large multinational company of several families improve do aspect these shortcomings better, and the product of domestic enterprise always this can not accomplish that better effects is all arranged simultaneously aspect several in outward appearance, heat-proof aging, ethylene glycol resistant, high strength.The present technique invention produces in order effectively to overcome this technological deficiency.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of product heat-proof aging and this highly-polished ethylene glycol resistant composite reinforced nylon 66 raw material that can have better effects simultaneously aspect several of ethylene glycol resistant and high strength in outward appearance is provided.
Technical scheme provided by the invention is as follows: a kind of highly-polished ethylene glycol resistant composite reinforced nylon 66 of the present invention, form nylon 66:50-70%, Halogen alkali-free glass fiber: 25-35% by weight by following composition; Thermo-stabilizer: 0.1-3.0%; Ethylene glycol resistant treatment agent: 0.2-1.5%; Glass treatment agent: 0.1-3.0%; Nucleator: 0.1-0.5%; The high pigment black masterbatch of nylon based: 1.0-2.5%; Other auxiliary agents: 1.3-5.5%.
Highly-polished ethylene glycol resistant composite reinforced nylon 66 Production Flow Chart of the present invention is: earlier nylon 66 particles were toasted 3-4 hour with the temperature of 100 degree, then with nucleator, thermo-stabilizer, the glass treatment agent, the ethylene glycol resistant treatment agent, the high pigment black masterbatch of nylon based, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, naturally place after 6 hours and carry out mixing extruding by side adding Halogen alkali-free glass fiber through twin screw extruder under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod makes a kind of highly-polished ethylene glycol resistant composite reinforced nylon 66 raw material through screening and dewatering again.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of highly-polished ethylene glycol resistant composite reinforced nylon 66 of the present invention and manufacture craft thereof, he possesses the outward appearance of best bright finish and the characteristic of secular heat-proof aging and tolerance ethylene glycol simultaneously under the prerequisite that keeps very good mechanical properties, and production procurement is convenient, all adopt homemade supplementary material and additive, also meet simultaneously all environmental requirements, comprehensive like this product competitiveness that improved.
Embodiment
Below be the most preferred embodiment of highly-polished ethylene glycol resistant composite reinforced nylon 66 raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of highly-polished ethylene glycol resistant composite reinforced nylon 66 is provided, and forms nylon 66:63.5%, Halogen alkali-free glass fiber: 30% by weight by following composition; Thermo-stabilizer: 0.7%; Ethylene glycol resistant treatment agent: 1.0%; Glass treatment agent: 0.8%; Nucleator: 0.2%; The high pigment black masterbatch of nylon based: 1.3%; Other auxiliary agents: 2.5%;
Earlier nylon 66 particles were toasted 3-4 hour with the temperature of 100 degree, then with thermo-stabilizer, glass treatment agent, nucleator, ethylene glycol resistant treatment agent, the high pigment black masterbatch of nylon based and other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, stainless steel, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather, place naturally then and re-use after making its sufficient reacting in 6 hours; Twin screw extruder uses cord wood in the same way parallel, 40 length-to-diameter ratios, and medium tenacity is sheared; The Halogen alkali-free glass fiber is added in proportion by the side; Keep vacuum state and 290 the degree condition is mixing extrudes; Adopt water-cooled tie rod pelletizing mode, promptly make the highly-polished ethylene glycol resistant composite reinforced nylon 66 raw material through screening and dewatering.
