Abstract
The invention provides closed-hole foamed rubber which is composed of, by weight, 85 parts of natural rubber, 15 parts of chloroprene rubber, 4-6 parts of zinc oxide, 7-9 parts of stearic acid, 1-2 parts of antiager 4020, 1-2 parts of stearic acid monoglyceride, 50-60 parts of naphthenic oil and the like. The closed-hole foamed rubber overcomes the defects in the prior art, is used for preparing gaskets arranged between mechanical sleeved parts, has the advantages of being good in elasticity, aging resistant, acid-base resistant, chemical dissolubility resistant, and capable of being used under severe environment conditions.
Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of closed-cell foam rubber.
Background technology
Closed-cell foam rubber generally is mainly used in the sealing between mechanical part, is used for protecting mechanical part.As air filter on automobile, casing is that the external structure of necessary protection is provided for filter core, and the both ends of the surface of filter core must be installed rubber cradle, for reaching corresponding sealing property.Rubber cradle should have the good performances such as good springiness, heat-resisting water-fast steam.Rubber erosion resistance and the elasticity of prior art are inadequate, install and use the life-span short in mechanical part.
Summary of the invention
The object of the present invention is to provide a kind of closed-cell foam rubber, this rubber is for the preparation of the packing ring with between machinery socket parts, has advantages of good springiness, ageing-resistant, acid and alkali-resistance, chemically-resistant dissolubility, can under the rugged environment condition, use.
Technical solution of the present invention is achieved as follows:
A kind of closed-cell foam rubber, the component that contains following weight part:
15 parts of zinc oxide 4-6 parts of 85 parts of chloroprene rubbers of natural rubber
Stearic acid 7-9 part antioxidant 4020 1-2 part glyceryl monostearate 1-2 part
Paraffin 1-3 part NOBS promotor 3-3.5 part sulphur 2.2-3.2 part
Blowing agent H 3-5 part calcium carbonate or the strong powder 150-220 of magnesium part naphthenic oil 50-60 part.
A kind of closed-cell foam rubber, preferably the weight part of each component is preferably:
15 parts of zinc oxide 4-6 parts of 85 parts of chloroprene rubbers of natural rubber
1.5 parts of 1.5 parts of glyceryl monostearates of 8 parts of antioxidant 4020s of stearic acid
3 parts, 3 parts of sulphur of 2 parts of NOBS promotor of paraffin
55 parts of 4 parts of calcium carbonate of blowing agent H or 200 parts of naphthenic oils of the strong powder of magnesium.
Natural rubber is a kind of natural high moleculer eompound that polyisoprene is main component of take.Natural rubber has higher elasticity at normal temperatures, slightly is with plasticity, has extraordinary physical strength, has good flexible resistance, electrical insulating property, has alkaline resistance properties preferably, but not anti-dense strong acid.
Chloroprene rubber claims again neoprene, is that chloroprene (being chlorbutadiene) has good physical and mechanical properties for the elastomerics that main raw material carries out α-polymerization generation, and oil resistant is heat-resisting, anti-combustion, anti-daylight, anti-ozone, acid and alkali-resistance, chemical-resistant reagent.
Compared with the prior art, beneficial effect of the present invention is as follows:
This rubber of the present invention is for the preparation of the packing ring with between machinery socket parts, has advantages of good springiness, ageing-resistant, acid and alkali-resistance, chemically-resistant dissolubility, can under the rugged environment condition, use.
