Abstract
The invention relates to an organic polymer composite material, more specifically, in particular to efficient environment-friendly toughened POM (Polyoxymethylene) and a preparation technology thereof. The efficient environment-friendly toughened POM comprises the following components according to weight ratio: 50-75% of polyformaldehyde, 15-25% of glass fibers, 0.3-1.0% of antioxidant 245, 0.3-1.0% of antioxidant 168, 0.4-1.0% of formaldehyde absorbing agent, 1-3% of lubricating agent and 0.1-3% of other auxiliaries. According to the efficient environment-friendly toughened POM and the preparation technology thereof, raw materials for production are convenient to purchase, so that the convenience for production and purchase is realized, and the produced products have high price/performance ratio, therefore the situation that toughened polyformaldehyde is restricted for use owing to various reasons at present is changed, and the competitive power is improved comprehensively.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of high-efficient environment-friendly toughened POM and manufacture craft thereof.
Background technology
The Research on Toughening of polyoxymethylene (POM) is difficult point of POM study on the modification. a lot of mechanisms and enterprise arranged at present to toughness reinforcing being studied of polyoxymethylene (POM), but often always do not exist certain aspect performance open defect or cost performance high and can not large-scale production.More research direction is in the market: some co-mixing systems of molten alloy reinforced polyformaldehyde (POM), such as the high-efficient environment-friendly toughened POM system of POM/PUR-T, POM/PP, POM/NBR, POM/PA and inorganic particulate;
The toughness reinforcing of POM the most easily goes with elastic body toughening.The research Polyurethane Thermoplastic Elastomer (TTO) of the high-efficient environment-friendly toughened POM of elastomerics recent years, paracril (NBR), terpolymer EP rubber (EPDM), 4 kinds of elastomericss of ethylene-octene copolymer (POE) are toughness reinforcing to POM's, wherein best with the toughening effect of TPU
Have the following disadvantages in the existing polyoxymethylene toughening technology:
Although 1, by with elastomerics can larger raising polyoxymethylene shock strength, tensile strength and the rigidity of polyoxymethylene decline by a big margin, and are difficult to obtain the polyoxymethylene of strong and unyielding comparatively balance; Although the polymkeric substance such as nano-rubber can improve the toughness of polyoxymethylene, increase rate is little, the polyoxymethylene blends of the high tenacity that is difficult to make; Elastomerics and nano-rubber are expensive, and the high-ductility polyformaldehyde cost that makes is higher;
2, have coating, peel off, the ultrathin composite powder of the isostructural elastomerics of intercalation and inorganic superfine powder body; with polyoxymethylene blended; the performance advantage that realizes elastomerics and ultrafine inorganic powder is complementary; significantly reduce expensive elastomeric consumption; can prepare and have good rigidity and toughness, and the low high-ductility polyformaldehyde blend of material cost, although material cost is low; but exist inconvenient mass-producing to produce in a large number, quality product is difficult to control stable shortcoming simultaneously.
Summary of the invention
The object of the invention is to overcome the defective of prior art, a kind of production and easy to use is provided, the improvement toughness environmental protection polyoxymethylene raw material that cost performance is high.
Technical scheme provided by the invention is as follows: toughness reinforcing environmental protection POM, formed by weight by following composition, polyoxymethylene: 50-75%, glass fibre: 15-25%, oxidation inhibitor 245:0.3-1.0%, irgasfos 168: 0.3-1.0%, formaldehyde absorbent: 0.4-1.0%, lubricant: 1-3%, other auxiliary agent: 0.1-3%.
Toughness reinforcing environmental protection POM raw material production flow process of the present invention is: with polyoxymethylene, oxidation inhibitor 245, irgasfos 168, formaldehyde absorbent, lubricant, other auxiliary agent proportionally after the weighing in mixer low speed mixing 10 minutes, melt flow rate (MFR) is 9, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; The extruding pelletization temperature evenly reduces by section step by step in 180-165 degree interval, in the screw combinations situation that medium tenacity is sheared, add glass fibre by the side through twin screw extruder again and carry out mixing extrusion, adopt water cooling bracing pelletizing mode, namely make high-efficient environment-friendly toughened POM raw material.
The present invention has effectively overcome the defective of existing high-efficient environment-friendly toughened POM, has the following advantages:
A kind of high-efficient environment-friendly toughened POM of the present invention and manufacture craft thereof, the materials procurement of its production usefulness is convenient, production and easy to use, and the product cost performance of producing is high, so just change reinforced polyformaldehyde and be limited because of various reasons at present the situation used, improved competitive power comprehensively.
Embodiment
Below be the most preferred embodiment of toughness reinforcing environmental protection POM raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of high-efficient environment-friendly toughened POM raw material is provided, and is made of by weight polyoxymethylene following composition: 75%, glass fibre: 20%, oxidation inhibitor 245:0.5%, irgasfos 168: 0.5%, formaldehyde absorbent: 0.5%, lubricant: 2%, other auxiliary agent: 1.5%.
Polyoxymethylene adopts the standard flow grade, with polyoxymethylene, oxidation inhibitor 245, irgasfos 168, formaldehyde absorbent, lubricant, other auxiliary agent proportionally after the weighing in mixer low speed mixing 10 minutes, melt flow rate (MFR) is 9, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; The extruding pelletization temperature evenly reduces by section step by step in 180-165 degree interval, in the screw combinations situation that medium tenacity is sheared, add glass fibre by the side through twin screw extruder again and carry out mixing extrusion, adopt water cooling bracing pelletizing mode, namely make high-efficient environment-friendly toughened POM raw material.
