Description
Technical field
The invention belongs to the polyacrylate(s) elastomerics, is a kind of core-shell type double activated acrylate elastomer, particularly preparation method specifically.
Background technology
Viton (FKM) is the synthetic macromolecule elastomerics that contains fluorine atom on the carbon atom of main chain or side chain, and it is widely used in many fields such as space flight, military project, national defence, automobile, petrochemical complex.The viton goods are mainly used in sealing member, packing ring, pad, barrier film, sebific duct, oil sealing, lining, anticorrosive products and electrical isolation goods.
Viton is most widely used to be automotive field, accounts for to use 60～70% of total amount.On automobile component, can be used as motor spirit flexible pipe, refueling hose, petrolift, air-conditioning plant O shape circle, reach the sealing material of jet apparatus, power piston, valve stem, bent axle, compressor of air conditioner.The automotive sealant that rubber is made in use, except the effect that is subjected to stress, strain, high temperature and low temperature, also be subjected to the erosion of oil product (oil fuel, lubricating oil), chemicals (alcohol, deicing fluid, scavenging solution, braking fluid, sulfuric acid, nitric acid) and biology (mould, bacterium, insect) etc.During product design, as can not consider the independent and synergy of working conditions comprehensively, will cause damage intensity to be accelerated, cause shorten work-ing life.Particularly along with the development of automotive industry and motorway, the travel speed of automobile significantly improves, so that the use temperature of oil sealing significantly rises, the oil temperature at the bent axle place of engine is substantially more than 110 ℃, therefore to the also corresponding raising of specification of quality of the rubber seal of automobile accessories.Traditional viton elaxtic seal can't satisfy high temperature, at a high speed, the actual operation requirements of high abrasion.
China begins to develop viton from the sixties in 20th century, successively successfully develops 23 types, 26 types, 246 types, TP-2 type etc. take polyolefine as main viton and the basic viton of the inferior pin of carboxyl.Develop again perfluoroelastomers the eighties in 20th century and fluoridized phosphorus rubber etc.
In order to improve the performance of viton and goods, a large amount of research work have been carried out in modification and the processing of viton both at home and abroad.At present, the modification of viton mainly contains both direction: the one,, pass through backbone modification, exploitation such as fluoroether rubber, trifluoropropyl siloxane, ehter bond is introduced the viton main chain, increased the flexibility of molecule, kept the original characteristics of viton when its low-temperature performance is improved greatly, but because the Development and Production high cost has greatly limited its promotion and application; The 2nd,, rubber blending, with viton and some conventional rubbers, specialty elastomer and usefulness, so that it is more excellent to obtain performance, the material that cost is lower.
Blending and modifying is a kind of preferably method, but has the following disadvantages: the cost performance that (1) makes novel type fluorubber is not high.Fluoroether rubber, trifluoropropyl siloxane make its price even are higher than viton because cost of development is too high, can only be used under the relatively harsher environment of condition, and promotion and application are restricted; (2) blending and modifying between the viton is restricted to the modification of viton performance.Rubber of the same type has determined that it causes that by the rubber self structure performance deficiency is restricted in improvement.Its cost is difficult to be reduced.Though and the blend of viton and fluoroether rubber can well improve the low-temperature performance of viton, cost is higher; (3) blend of viton and other rubber is difficult kind to the low-temperature performance of viton.Blending and modifying can improve the elasticity of viton, the improvement of the single performance such as processing characteristics, but very few to improving the viton low-temperature performance and considering the aspect research of a plurality of defectives.
Acrylic elastomer (ACM) itself is the specialty elastomer of a kind of high temperature resistant, oil resistant, ageing-resistant performance excellence, but, remains in shortcoming aspect the low temperature resistant and tear resistance at the modification viton.
Summary of the invention
For the deficiency that prior art exists, problem to be solved by this invention provides core-shell type double-active group acrylate elastomer of a kind of low temperature resistant and tear resistance and preparation method thereof.
Technical scheme of the present invention is achieved in that a kind of preparation method of core-shell type double activated acrylate elastomer; specifically may further comprise the steps: acrylate monomer, the acrylate that contains active group, compound emulsifying agent are joined in the kneader; be warming up to 60～90 ℃; insulation reaction 0.8～1.2h; then add vulcanizing agent and oxidation-reduction initiator; under the nitrogen protection; be warming up to 80～100 ℃; insulation reaction 1.5～2.0h; be cooled at last 40～50 ℃, make core-shell type double activated acrylate elastomer.
Further, described acrylate monomer 70～100 weight parts contain acrylate 50～80 weight parts of active group, compound emulsifying agent 15～30 weight parts, vulcanizing agent 8～20 weight parts, oxidation-reduction initiator 5～8 weight parts.
Described acrylate monomer is one or more in methyl acrylate, ethyl propenoate, the butyl acrylate.
