Abstract
The present invention relates to acrylonitrile rubber composite and manufacture method and application that three kinds of gaskets are used, this class acrylonitrile rubber composite has paracril, natural rubber, sulphur, vulcanization accelerator and pigment, also contains and replenish elastomerics dust cork and/or supporting material asbestos, macrofiber flax silk, mixing and get through secondary, it is good, ageing-resistant that the gasket that is made by this class acrylonitrile rubber composite has elasticity, thermostability and oil-proofness.
Description
Existing gasket is pressed into Precondensed UreaFormaldehyde Resin and granulated cork, after saw blade is put the resin dip, and airing or oven dry, punch die moulding then.Its thermostability and oil-proofness are poor, and easily aging, other has the paper washer easy oil leakage, is not durable, and will cements with viscose glue, use inconvenient.
It is a kind of for making good springiness that the object of the invention is to provide, and thermostability and oil-proofness are good, the acrylonitrile rubber composite that ageing-resistant gasket is used.
Technical solution scheme of the present invention is such: the contriver is through test of many times, and the result shows, is that cross-linking system is made external phase with rubber, mainly is fourth glue
, n=3000-7000 in the formula, and use a small amount of natural rubber
; As supporting material, is the additional elastomerics of rubber with the dust cork with asbestos, macrofiber flax silk, white carbon black, also has preventing aging system: antioxidant D (
), anti-aging agent RD (
), antioxidant A (
) etc., and be added with color pigments: iron oxide red (Fe
2O
3), golden light is bright red
According to each position of engine gasket required the performance difference, acrylonitrile rubber composite of the present invention has three kinds, so that make three kinds of gaskets, first kind is to use for system cork-rubber pad, the parts by weight of its each component are: butadiene-acrylonitrile rubber 70-90, natural gum 10-30, Sulfur 1-3, vulcanization accelerator 2.5-4.5, protective agent 1.5-3.5, white carbon black 10-30, dust cork 140-200, iron oxide red 0.1-0.3, the bright red 0.5-1.5 of golden light are mainly used in more coarse flat seal.Second kind is to use for system asbestos flax silk rubber pad, the parts by weight of its each component are: butadiene-acrylonitrile rubber 70-90, natural gum 10-30, Sulfur 1-3, vulcanization accelerator 2.5-4.5, protective agent 1.5-3.5, white carbon black 10-30, asbestos 100-120, macrofiber flax silk 130-170, iron oxide red 0.1-0.3, the bright red 0.5-1.5 of golden light, this gasket is used for two machining planes, more stressed flat seal.The third is that the parts by weight that contain dust cork, asbestos and macrofiber flax silk, each component simultaneously are: butadiene-acrylonitrile rubber 70-90, natural gum 10-30, Sulfur 1-3, vulcanization accelerator 2.5-4.5, protective agent 1.5-3.5, white carbon black 10-30, the weight ratio of a kind of dust cork, asbestos, macrofiber flax silk is 1: 1: 1.3 to 1: 3: 4 mixture 150-300, iron oxide red 0.1-0.3, the bright red 0.5-1.5 of golden light.This acrylonitrile rubber composite has certain rigidity and elasticity, is used to make the gasket of discontinuity.
Production technique of the present invention is: with butadiene-acrylonitrile rubber, after natural gum mixes, plasticate with the 400mm mill, its temperature is 30-40 ℃, add Sulfur, promotor, anti-aging agent, white carbon black, iron oxide red, the bright red mixture of golden light 400mm mill mixing, its temperature is 40-50 ℃, draw red rubber unvulcanizate, add dust cork or asbestos then, the mixture of flax silk or dust cork, it is mixing that asbestos and macrofiber flax silk mixture carry out secondary, parked 24 hours, and made its inner fully infiltration, use the 230mm mill then, speed ratio is 1: 1, the roller temperature is 30-40 ℃, and the heat refining slice is behind the mould stamp, vulcanize with vulcanizing press, its temperature is 135-155 ℃, and the time is 3-5 minute, pressure 1-1.2MPa.The finished product are red-brown.
Purposes of the present invention and result of use are: the gasket with acrylonitrile rubber composite of the present invention is made, can be used for the oil engine linker, and play in conjunction with the flat seal effect, fundamentally solved " three leak " problem of oil engine.Make 200 hours continuous serviceabilitys through Yulin Diesel Engine Plant, Guangxi Zhuang Nationality Autonomous Region and test, test-results shows to have following performance: 1. good springiness under the not too smooth condition of bonding surface, can guarantee the stopping property of diesel engine.2. Heat stability is good, this product installation was used after for some time, opened and inspect and did not have the phenomenon of damage, in-50-250 ℃ scope, can reuse.3. oil-proofness is good, and dip 24 hours can remain unchanged, and presses nothing to damage phenomenon through oil immersion in the use.4. ageing-resistant performance is good, not influenced by the general chemistry material, and fast light, oxygen, ozone, mechanical vibration are aging.5. can adopt one time sulfidization molding according to user's design paper, material object, directly installation is used.
Embodiment 1, has elasticity according to cork, compress on-deformable characteristics, with the dust cork is main raw material, add rubber and other additive, make system parts flat seal cork-rubber pad, the acrylonitrile rubber composite of usefulness, the parts by weight of its each component are: butadiene-acrylonitrile rubber 80, natural gum 20, Sulfur 2.2, promotor 3.5, anti-aging agent 2.5, white carbon black 20, cork 170, iron oxide red 0.2 golden light bright red 1.
