Description
Technical field:
The present invention relates to field of rubber technology, specifically the production technology of a kind of water pump water pump buffer rubber gasket。
Background technology:
The size of the elastomeric material fissipation factor of damping is not only relevant with the structure of rubber itself, and relevant with temperature and frequency。At normal temperatures, the fissipation factor of natural rubber (NR) and butadiene rubber (BR) is less; the fissipation factor of butadiene-styrene rubber (SBR), neoprene (CR), EP rubbers (EPR), polyurethane rubber (PU) and silicone rubber is placed in the middle, and the fissipation factor of butyl rubber (HR) and nitrile rubber (NBR) is maximum。
Elastomeric material as damping purpose generally divides 5 kinds, and namely NR, SBR, BR are General Purpose Rubber material；NBR is used for oil resistant vulcanizate；CR is used for the vulcanizate of resistance to weather；IIR is for height damping vulcanizate；EPR is used for resistance to heat vulcanizate。Although NR fissipation factor is less, but its combination property is best, has the elasticity of excellence, fatigue durability is good, and raw heat is low, and creep is little, good with metalwork cement properties, tolerance to cold, electrical insulating property and processing characteristics, therefore NR is widely used as damping purpose, but a certain single rubber types all has certain weakness, natural rubber price is higher, and some rubber dissipation factor is big, the more weak easy generation permanent deformation of some elasticity, the low easy cracking of some toughness。
Summary of the invention:
The technical problem to be solved is in that to provide a kind of low price, and elastic high, toughness is high, long service life, it is not easy to the production technology of the water pump buffer rubber gasket of permanent deformation,
In order to realize the purpose of the present invention, adopted following technical scheme:
A kind of production technology of water pump water pump buffer rubber gasket, it is characterised in that: comprise the following steps,
(1), dispensing: with raw material, described raw material includes natural rubber 20～30 parts, butadiene-styrene rubber 20～30 parts, butadiene acrylonitrile rubber 10～20 parts, toughener 3～8 parts by weight, elasticator (elasticizer) 3～8 parts, calcium zincates 0.2～1 part, 3～8 parts of Talcum, bentonite 3～8 parts, zinc oxide 1～1.5 part, stearic acid 0.05～0.08 part, plasticizer 0.3～0.5 part, age resistor 20～30 and calcium carbonate 10～15 parts；Described toughener is polyvinyl butyral resin and dioctyl phthalate, and both adding proportions are 2:1；Described elasticator (elasticizer) is butadiene copolymer zoarium, butyl ester and acrylic acid methyl ester., and the adding proportion of three is 2:2:1；
(2), mixing: putting into after being sufficiently mixed by raw material and carry out mixing process in batch mixer, melting temperature is 40～70 DEG C, and mixing time is 30～40 minutes；
(3), mould molding: use mould to be shaped processing by the raw material after mixing, then cool down。
Described natural rubber needs to carry out refining glue process before mixing, and glue furnacing temperature is about about 60 DEG C, and the persistent period is 48 hours。
The described rubber after mould molding needs to carry out destressing process。
Described plasticizer is chlorinated paraffin。
The present invention wants the advantage in conjunction with the blended rubber obtained with rubber by natural rubber and other rubber, compares natural rubber and has and reduce cost。The mixture of elasticator (elasticizer) diene copolymerization body in the present invention, butyl ester and acrylic acid methyl ester., is greatly increased the elasticity of rubber so that caoutchouc elasticity foot, buffering effective, and is not easy to produce permanent deformation。Toughener in the present invention is polyvinyl butyral resin and dioctyl phthalate, it is possible to being greatly increased the toughness of rubber so that rubber is not easily susceptible to cracking, intensity is higher, longer service life。
The invention has the beneficial effects as follows: the rubber low price that the present invention produces, elastic high, toughness is high, long service life, it is not easy to permanent deformation。
Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with instantiation, the present invention is expanded on further。
