Abstract
The invention discloses a high-rigidity extruded nylon 66 material, which consists of the following components in percentage by weight: 5 to 98.5 percent of nylon 66, 0.1 to 3 percent of thickening agent, 0.1 to 3.0 percent of heat stabilizer, 0.1 to 3.0 percent of nucleating agent and 1.3 to 5.5 percent of other aids. Compared with the traditional nylon 66 material, the high-rigidity extruded nylon 66 material has the performance improved by 20 to 50 percent and can be subjected to extrusion molding; meanwhile, the production efficiency is high, the original advantages of the nylon 66 are maintained, the specific gravity, the appearance and the lustre are not changed, and the products can be easily recycled completely when scraped; meanwhile, the high-rigidity extruded nylon 66 material meets all other environmental protection requirements; therefore, the product competitiveness is comprehensively improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of high rigidity extrusion grade nylon 66 material, the invention still further relates to the preparation method who makes this high rigidity extrusion grade nylon 66 material.
Background technology
The intensity of nylon 66 material own is good, be convenient to process for processing, be extensive use of at present, but in a lot of places, or insufficient strength, therefore, launched nylon 66 is carried out composite modified research, improved the comprehensive physical and mechanical property of nylon 66 material, keep simultaneously that original advantage is existing to be required under the into once high-intensity situation, generally be to adopt the Reinforced Nylon material, or adopt the method reply of high-strength special type engineering plastic materials, still, the Reinforced Nylon material by contrast, had the not enough smooth finish of outward appearance again, proportion is bigger, anisotropic shortcoming; The high-strength special type engineering plastic materials then exists cost obviously significantly to improve, and production and processing technology requires harsh shortcoming.
Summary of the invention
The objective of the invention is to, but the high preferably rigidity injection molding grade nylon 66 of the lower physicals of a kind of cost material is provided.
Technical scheme provided by the invention is as follows: a kind of high rigidity extrusion grade nylon 66 material, form nylon 66: 5-98.5% by weight by following composition; Tackifier: 0.1-3%; Thermo-stabilizer: 0.1-3.0%; Nucleator: 0.1-3.0%; Other auxiliary agents: 1.3-5.5%.
The preparation method of high rigidity extrusion grade nylon 66 material of the present invention, comprise the steps: earlier with nylon 66, tackifier, thermo-stabilizer, nucleator, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, naturally place after 6 hours more in time the screw combinations situation of shearing in certain intensity through twin screw extruder and keep under the certain vacuum pressure state, with mixing the extruding of 270 degree, pelletizing makes high rigidity extrusion grade nylon 66 material through screening and dewatering.
The advantage of the high rigidity extrusion grade of the present invention nylon 66 material: more traditional nylon 66 material, performance can improve 20-50%, can adopt the extrusion moulding mode, while production efficiency height, keep nylon 66 original advantages, proportion, outward appearance, gloss all not have to change, and a hundred per cent recycling more easily during product rejection, also meet simultaneously other all environmental requirement, comprehensive like this product competitiveness that improved.
Embodiment
Below be the embodiment of high rigidity extrusion grade nylon 66 material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of high rigidity extrusion grade nylon 66 material is provided, and it forms nylon 66: 91.7% by weight by following composition; Tackifier: 2%; Thermo-stabilizer: 1.5%, nucleator: 0.3%, other auxiliary agents: 4.5%.
The preparation method who makes high rigidity extrusion grade nylon 66 material is: earlier with nylon 66, tackifier, thermo-stabilizer, nucleator, 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, liquid 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 the 36-40 length-to-diameter ratio, and certain intensity is sheared; Keep the certain vacuum state and 270 the degree condition is mixing extrudes; Adopt water-cooled tie rod pelletizing or underwater cutpellet mode, promptly make high rigidity extrusion grade nylon 66 material through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
