Abstract
The present invention relates to recipe and additive of rubber and plastic. Into rubber and plastic, proper amount of carbon fiber is added before molding. The present invention has obviously raised tearing strength, flex strength and toughness, capacity of eliminating electrostatic harm and prolonged service life.
Description
The present invention relates to the prescription and the additive of a kind of rubber and plastics.At present in rubber and plastic products, the shell of the rubber diaphragm of railway freight-car brake valve and computer particularly, because its anti-influence of opening and static low with flexual strength, cause the electric elements in brake valve rubber diaphragm and the computer often to damage, cause problems such as serious parking accident and computer damage, work the mischief for people's life and property, and make troubles to work.
Purpose of the present invention is that a kind of tear-proof and the anti-flexual strength and toughness that can greatly improve rubber and plastic products will be provided, and can eliminate the rubber that static works the mischief and the prescription and the additive of plastics.
For achieving the above object, the present invention is when two kinds of rubber and additive are mixed and before the plastic raw materials granulation, adds together mix behind an amount of carbon fiber (or granulation), die forming again in its raw material.Compare with prior art, have the tearing toughness and flexual strength and the toughness that significantly improve rubber and plastic products, and the harm that can eliminate static more up hill and dale and caused, increase the service life.
Be described further below in conjunction with exemplary embodiments and accompanying drawing:
Fig. 1 is the structure chart of railway freight-car with the rubber diaphragm of brake valve.
Fig. 2 is the structure chart that is used for the plastic casing of little electrical component.
In Fig. 1, the railway freight-car rubber diaphragm of brake valve, be with natural rubber and neoprene mixing or butadiene rubber and neoprene mixing or nitrile rubber and butadiene-styrene rubber mixing or neoprene and nitrile rubber mixing, after respectively the virgin rubber of above-mentioned four kinds of mixed rubbers being cut into small pieces, add the short silk of an amount of carbon fiber and other additive (vulcanizing agent, reinforcing agent, softening agent, filler, age resistor, vulcanization accelerator, activating agent is quickened in sulfuration, colouring agent etc.) carry out together mixing, evenly mix until each thing, the good rubber that will mix again carries out die forming and sulfuration, can make rubber diaphragm.
Above-mentioned four groups of mixed rubbers also can be distinguished and only add other additive, do not mix and do not add the short silk of carbon fiber, and the good rubber that will mix again carries out die forming and sulfuration, can make rubber diaphragm.
The railway freight-car rubber diaphragm of brake valve, also can be with natural, neoprene, along rubber such as fourth, fourth cyanogen, butylbenzene, second third, butyl, isoamyls, after wherein a kind of rubber or the wherein multiple rubber mix, adding the short silk of an amount of carbon fiber and other additive mixes together, the good rubber that will mix again carries out die forming and sulfuration, can make rubber diaphragm.
The railway freight-car rubber diaphragm of brake valve, again can be with natural, neoprene, along rubber such as fourth, fourth cyanogen, butylbenzene, second third, butyl, isoamyls, after wherein a kind of rubber or the wherein multiple rubber mix, only add other additive, do not mix and do not add carbon fiber, the good rubber that will mix again carries out die forming and sulfuration, can make rubber diaphragm.
In Fig. 2, the plastic casing that is used for little electrical component (as computer etc.), be in plastic raw materials (powdery or granular resin), to add after an amount of carbon fiber and filler, curing agent, reinforcing agent, stabilizing agent, lubricant, colouring agent etc. mix, again the plastic material (or after granulation) that mixes is carried out mould and be shaped, can make plastic casing.
Carbon fiber in adding above-mentioned rubber or plastics is than long filament, also short silk, powder shape also.
Carbon fiber in adding above-mentioned rubber or plastics, its content is 0.5%～30% of rubber or plastics volume capacity.
