Abstract
The invention discloses an injection molding grade nylon material reaching cast nylon strength. The material comprises the following components in percentage by weight: 6.5 to 98.5 percent of nylon, 0.1 to 3 percent of toughening 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 auxiliary agents. The material has the advantages that: the performance is basically the same as that of the commonly used cast nylon material, but compared with the commonly used cast nylon material, the injection molding grade nylon material has the raw materials which are more convenient to produce and process; the injection molding grade nylon material can adopt an injection molding way; and the injection molding grade nylon material has high production efficiency and can be reclaimed at the same time.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of injection-level nylon material that reaches nylon monomer-cast nylon intensity.The invention still further relates to the method for making this nylon raw material.
Background technology
The fusing point of nylon monomer-cast nylon is higher, has good physical and mechanical property and wear resistance and self lubricity.But his forming process is bad, and the hardness ag(e)ing rate is low, the cost height.There is physical and mechanical properties shortcoming on the low side relatively by contrast in nylon 6 material, but the considerably cheaper of process for processing cost value comparatively speaking, can adopt the processing mode of injection moulding, and the efficient height is convenient to produce the complex construction product.Therefore, launched nylon 6 is carried out composite modified research, how to have improved the comprehensive physical and mechanical property of nylon 6 material, made its index of correlation that reaches the nylon monomer-cast nylon material become chemical industry problem demanding prompt solution.
Summary of the invention
The objective of the invention is to, but a kind of injection-level nylon material that reaches nylon monomer-cast nylon intensity of injection moulding easy to process is provided.
Technical scheme provided by the invention is as follows: a kind of injection-level nylon material that reaches nylon monomer-cast nylon intensity, and it forms nylon 6: 5-98.5% by weight by following composition; Toughner: 0.1-3%; Thermo-stabilizer: 0.1-3.0%; Nucleator: 0.1-3.0%; Other auxiliary agents: 1.3-5.5%.
The injection-level nylon preparation methods that reaches nylon monomer-cast nylon intensity of the present invention, comprise the steps: earlier with nylon 6, toughner, 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 the injection-level nylon material that reaches nylon monomer-cast nylon intensity through screening and dewatering.
The present invention reaches the advantage of the injection-level nylon material of nylon monomer-cast nylon intensity: the general nylon monomer-cast nylon material that uses is identical substantially with at present for performance, but the starting material process for processing is convenient by contrast, can adopt injection molding, while production efficiency height, and more absolutely recycling during product rejection, also meet simultaneously other all environmental requirement, comprehensive like this product competitiveness that improved.
Embodiment
Below be the embodiment that reaches the injection-level nylon material of nylon monomer-cast nylon intensity of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of injection-level nylon material that reaches nylon monomer-cast nylon intensity is provided, and forms nylon 6: 91.7% by weight by following composition; Toughner: 2%; Thermo-stabilizer: 1.5%, nucleator: 0.3%, other auxiliary agents: 4.5%.
Earlier with nylon 6, toughner, 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 the injection-level nylon material that reaches nylon monomer-cast nylon intensity 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.
