Abstract
A production technology of pump-used cushion rubber relates to the technical field of rubber and comprises the following steps: compounding: preparing the following raw materials in parts by weight: 20-30 parts of natural rubber, 16 parts of butadiene rubber, 10 parts of tread reclaimed rubber, 3 parts of flexibilizers, 3 parts of elasticators, 0.2 part of calcium zincate, 1 part of zinc oxide, 0.05 part of stearic acid, 0.3 part of a plasticizer, 20 parts of an antiager and 10 parts of calcium carbonate, wherein the flexibilizers are polyvinyl butyral and dioctyl phthalate of which the adding proportion is 2: 1, and the elasticators are a butadiene copolymer, butyl ester and maleic anhydride of which the adding proportion is 2: 2: 1; mixing: after fully mixing the raw materials, placing the obtained mixture in a mixer for 30-min mixing at 40 DEG C; die molding: using a die to mold the mixed raw materials, and then cooling. The pump-used cushion rubber produced by the production technology is low in price, high in elasticity and toughness, long in service life and low in probability of permanent deformation.
Description
Technical field:
The present invention relates to field of rubber technology, specifically the production technique of a kind of pump cushion plate rubber.
Background technology:
The size of the elastomeric material dissipation factor of damping is not only relevant with the structure of rubber itself, and relevant with temperature and frequency. At normal temperatures, the dissipation factor of natural rubber (NR) and cis-1,4-polybutadiene rubber (BR) is less; the dissipation factor of styrene-butadiene rubber(SBR) (SBR), chloroprene rubber (CR), ethylene-propylene rubber(EPR) (EPR), urethanes (PU) and silicon rubber is placed in the middle, and the dissipation factor of isoprene-isobutylene rubber (HR) and paracril (NBR) is maximum.
Elastomeric material as damping object generally divides 5 kinds, and namely NR, SBR, BR are General Purpose Rubber material; NBR is used for oil resistant cross-linked rubber; CR is used for the cross-linked rubber of resistance to weather; IIR is used for high damping cross-linked rubber; EPR is used for resistance to thermovulcanizate. Although NR dissipation factor is less, but its over-all properties is best, has excellent elasticity, resistance to fatigue is good, and heat-dissipating is low, and creep is little, good with metalwork cement properties, winter hardiness, electrical insulating property and processing characteristics, therefore NR is widely used as damping object, but a certain single rubber types all has certain weakness, natural rubber price is higher, and some rubber consume factor is big, the more weak easy generation permanent deformation of some elasticity, the low easy cracking of some toughness.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of price cheap, elasticity height, toughness height, it may also be useful to the life-span is long, it is not easy to the pump of the permanent deformation production technique of cushion plate rubber,
In order to realize the object of the present invention, adopted following technical scheme:
The production technique of a kind of pump cushion plate rubber, it is characterised in that: comprise the following steps,
(1), prepare burden: with raw material, described raw material comprises natural rubber 20��30 parts, cis-1,4-polybutadiene rubber 16��26 parts, tread reclaimed rubber 10��20 parts, toughner 3��8 parts by weight, elasticator 3��8 parts, calcium zincates 0.2��1 part, 1��1.5 part, zinc oxide, stearic acid 0.05��0.08 part, 0.3��0.5 part, softening agent, anti-aging agent 20��30 and 10��15 parts, calcium carbonate; Described toughner is polyvinyl butyral acetal and dioctyl phthalate (DOP), and both adding proportions are 2:1; Described elasticator is divinyl copolymer, fourth ester and toxilic acid glycosides, and the adding proportion of three is 2:2:1;
(2), mixing: putting into after fully being mixed by raw material and carry out mixing process in mixer, melting temperature is 40��70 DEG C, and mixing time is 30��40 minutes;
(3), mould molding: use mould that the raw material after mixing is carried out forming processes, then cool.
Described natural rubber needs to carry out refining glue process before mixing, and glue furnacing temperature is about about 60 DEG C, and the time length is 48 hours.
The described rubber after mould molding needs to carry out destressing process.
Described softening agent is clorafin.
The present invention wants to have the advantage of rubber in conjunction with the blended rubber obtained by natural rubber and other rubber, compares natural rubber and has and reduce cost. The mixture of elasticator diene copolymer in the present invention, fourth ester and toxilic acid glycosides, increases the elasticity of rubber greatly so that caoutchouc elasticity foot, buffering effective, and is not easy to produce permanent deformation. Toughner in the present invention is polyvinyl butyral acetal and dioctyl phthalate (DOP), it is possible to greatly increase the toughness of rubber so that rubber is not easy cracking, and intensity is higher, it may also be useful to the life-span is longer.
The invention has the beneficial effects as follows: the rubber price that the present invention produces is cheap, elasticity height, toughness height, it may also be useful to the life-span is long, it is not easy to permanent deformation.
