Abstract
The invention relates to an organic polymer composite material, in particular to high wear-resistant lubricating plastic. The high wear-resistant lubricating plastic comprises the following components in percentage by weight: 75-92.5 percent of polyformaldehyde, 1.5-6.5 percent of silicon series lubricating agent, 0.5-3.2 percent of toughener, 0.5-4.8 percent of flame retardant, 0.1-0.4 percent of coupling agent, 0.5-3.2 percent of mica, 0.3-2.0 percent of antioxidant and 0.1-5.5 percent of activated carbon. According to the high wear-resistant and self-lubricating polyformaldehyde and a production process thereof disclosed by the invention, various agents with a certain proportion are added, so that the produced plastic has the characteristics of high wear resistance and high lubrication performance; and in addition, the plastic is convenient for production and purchase, so that the competitiveness of a polyformaldehyd product is greatly improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of high abrasion lubricating plastic.
Background technology
The staple of plastics is a synthetic resins.This noun of resin is to be gained the name by the oozy lipid of plant-animal at first, and like rosin, shellac etc., at present resin is meant as yet not and various additive blended superpolymer.Resin accounts for 40%～100% of plastics gross weight.The fundamental property of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics is made up of synthetic resins basically, does not contain or contain less additive, like organic glass, PS etc.So-called plastics, it is a kind of in the synthetic resins in fact, shape is similar with the pine resin in the natural resin, but because of synthesizing through chemical strength again, and be referred to as plastics.Polyoxymethylene be a kind of high comprehensive performance the big kind of engineering plastics; Favorable mechanical performance, electrical property, wear resistance, dimensional stability and chemical proofing are arranged; Particularly resistance to fatigue and self lubricity, wear resistance are the highest in all thermoplasticss; Therefore; Be widely used in replacing various non-ferrous metals and alloy to make automobile, machinery, instrument, agricultural machinery, chemical industry component, like gear, cam, bearing, lining, packing ring, valve, liquid conducting pipes, handle and pressure vessels for the chemical industry or the like.
At present, thus on the market for make better wear resistance can broadened application the field, have a lot of mechanisms and enterprise that the wear resistance of improving of polyoxymethylene is studied; But owing to be difficult in cost control, improve wear resistance, control and decompose to improve and fail equilibrium aspect production stability or the like all the time, some plastics that are made with polyoxymethylene are owing to use for a long time; Begin wearing and tearing, the surface does not have lubricant effect, has had a strong impact on the production and the running of company; Though done a lot of improvement on the market but do not obtained effect preferably, the improvement that has the wear resistance of product, raw materials cost and production cost are too high; Be difficult to form industriallization, large-scale production; It is relatively good that other raw materials cost and production cost are controlled, but the improvement of the wear resistance of product is all little, DeGrain.
Summary of the invention
In order to overcome the defective of above-mentioned technology, the present invention provides a kind of wear resistance good, and has the high abrasion lubricating plastic of high lubricating property.
Technical scheme provided by the invention is following: a kind of high abrasion lubricating plastic of the present invention, by following composition by weight forming polyoxymethylene: 75-92.5%; Silicon base lubricant: 1.5-6.5%; Toughner: 0.5-3.2%; Fire retardant: 0.5-4.8%; Coupling agent: 0.1-0.4%; Mica: 0.5-3.2%; Oxidation inhibitor: 0.3-2.0%; Gac: 0.1-5.5%.
The Production Flow Chart of high abrasion lubricating plastic of the present invention is: at first, polyoxymethylene is dried in high temperature, remove impurity; In order to make the plastics make possess certain wear resisting property and lubricity, again polyoxymethylene is dissolved in the polyreaction of carrying out in the solvent that is mixed with silicon base lubricant, toughness reinforcing, fire retardant, coupling agent, mica, oxidation inhibitor, the temperature of reaction is controlled at 80 ℃; After reaction finished, the polymkeric substance that obtains was a latex, and polymkeric substance is placed in the mould; The heating while also is rotated, and energy of rotation makes latex can more be prone to incorporate in the mould, and reaction is about 10 minutes; Cool off again,, form the homogeneous phase layer of uniform thickness then with working cycle fusion gradually; At last, mould changes the cooling work area over to, through plenum or water spray cooling; Be placed on the WS then, can make and possess the lubricated plastics of high mechanical strength.
The advantage of high abrasion lubricating plastic of the present invention: through the interpolation of multiple a certain proportion of reagent; Even make the plastics of producing have high-wearing feature because of using for a long time or collision; Also be not prone to scratch, and lubricity strengthens also, possess certain aesthetics; And production procurement is convenient, has improved the polyoxymethylene competitiveness of product in market so greatly.
Embodiment
Below be the most preferred embodiment of high wear-resistant self-lubricating polyoxymethylene raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and the high abrasion lubricating plastic is provided, by following composition by weight forming polyoxymethylene: 87.4%; Silicon base lubricant: 3.5%; Toughner: 2.8%; Fire retardant: 1.9%; Coupling agent: 0.3%; Mica: 0.8%; Oxidation inhibitor: 1.2%; Gac: 2.1%.
At first, polyoxymethylene is dried in high temperature, remove impurity, then; Polyoxymethylene is dissolved in the polyreaction of carrying out in the solvent that is mixed with silicon base lubricant, toughness reinforcing, fire retardant, coupling agent, mica, oxidation inhibitor, the temperature of reaction is controlled at 80 ℃, after reaction finished, the polymkeric substance that obtains was a latex; Polymkeric substance is placed in the mould, and heating is also rotation simultaneously, and reaction is about 10 minutes, cools off again; With working cycle fusion gradually, form the homogeneous phase layer of uniform thickness then, last, mould changes the cooling work area over to; Through plenum or water spray cooling, be placed on the WS then, can make and possess the lubricated plastics of high mechanical strength.
The above; Be merely 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 technical scope that the present invention disclosed, and 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.
