Description
Technical field
The present invention relates to a kind of working method of superpolymer, be specifically related to a kind of modified EVA microporous foamed shoe-pad material and preparation method thereof.
Background technology
Development along with shoe-pad, the special-purpose footwear of various motions, the tourism footwear, the classification of leisure footwear is thinner, special-purpose footwear of sports events particularly, according to this sports events characteristic the more requirement of high technology content is proposed the footwear material, for example shock-absorbing, resilience, wear-resisting, anti-skidding and antibiotic, deodorization, breathe freely and wait requirement, for improving antidetonation, resilience, wear-resisting, requirement such as anti-skidding grade, in the prescription of microporous foam insole material, contain a large amount of rubber and macromolecular elastomer rubber and elastomerics, these materials usually raise with oil price, cause the promotion of insole material cost, bring very big difficulty to enterprise operation, it is enterprise's optimal selection that the rubber elastomer product of seeking low price replaces replacing high price rubber with part, chlorinated polyethylene rubber is compared with the most synthetic rubber of natural rubber, price is lower, is desirable substitute products.
Chlorinated polyethylene rubber is the chloride elastomerics that polyethylene makes through chlorination reaction, its rich raw material sources, manufacturing process is simple, with low cost, it is a kind of new type rubber material with development potentiality, material modified with the EVA that itself and terpolymer EP rubber Low Density Polyethylene (PE) are formed, guaranteeing that its rerum natura requires under prerequisite, substitute part EPDM and other rubber and can reduce production costs and improve economic benefit of enterprises and product market competitiveness.
Because the molecular chain of chlorinated polyethylene rubber is saturated, and contain polarity chlorine atom, thereby have good weather resisteant and performances such as ozone resistance, heat-resistant aging, resistance to chemical reagents, oil-proofness and difficult to burn, so the modified EVA microporous foam material of chlorinated polyethylene rubber can be applicable on heat-insulation material and the wrapping material.
Chinese patent CN102504398A discloses a kind of modified EVA foam and preparation method thereof and application.This modified EVA foam comprises ethene vinyl acetic monomer multipolymer, polyolefin elastomer, lignocellulose powder, whipping agent, bridging agent, promoting agent and zinc oxide.The mass ratio of described ethene vinyl acetic monomer multipolymer, described polyolefin elastomer, described lignocellulose powder, described whipping agent, described bridging agent, described promoting agent and described zinc oxide is 70: 30: 20-80: 3.0-5.0: 0.4-1.0: 1.0-3.0: 0.5-2.5.The proportion of this modified EVA foam is below 0.2, and quality is light, and compression is askew below 50%, can stand long dress, end lightweight in the footwear that are equipped with this modified foaming system, endurance quality are good, are applicable to the end and shoe-pad in the footwear of various sports classes and leisure, have important use and are worth.
Summary of the invention
The objective of the invention is to the deficiency at the physicals of existing pure EVA foam material, a kind of modified EVA microporous foamed shoe-pad material of the physicals that can the improve microcellular foam material demand to satisfy market and preparation method thereof is provided.
Described modified EVA microporous foamed shoe-pad material consisting of by mass ratio:
Described the 1st properties-correcting agent adopts chlorinated polyethylene rubber (CM) etc.
Described the 2nd properties-correcting agent adopts Low Density Polyethylene PE etc.
Described the 3rd properties-correcting agent adopts terpolymer EP rubber (EPDM) etc.
Described linking agent can adopt dicumyl peroxide (DCP) etc.
Described additional crosslinker can adopt cyanacrylate (TAIC) etc.
Described promotor can be adopted 1.2 1 thiol group tetrahydroglyoxalines (NA-22) etc.
Described whipping agent can adopt Cellmic C 121 (AC) etc.
Described promoter for blowing agent can adopt zinc oxide etc.
Described lubricant can adopt stearic acid etc.
Described modified EVA microporous foamed shoe-pad preparation methods may further comprise the steps:
1) whole raw materials is put into the Banbury mixer banburying;
2) with the material after the banburying in the mill thick logical after, packing, slice is cut into sheet material after the mixing of materials;
3) take by weighing sheet material and place mould, the heating mould crosslinked foaming namely gets modified EVA microporous foamed shoe-pad material after the die sinking.
In step 1), the temperature of described banburying can be 120～130 ℃, and the time of banburying can be 10～15min.
In step 2) in, described thick logical temperature can be 110～120 ℃, and described thick logical number of times can be 1～2 time, and the number of times of described packing can be 2～3 times.
In step 3), the vapour pressure of described heating mould crosslinked foaming can be 0.6～0.8MPa, and the time of crosslinked foaming can be 35～38min.
The EVA product that described EVA can adopt the Dow Chemical Company to produce.
Compare with modified system and the working method of existing EVA microcellular foam material, the present invention has the following advantages:
1) add chlorinated polyethylene rubber in the properties-correcting agent, because its main chain is ethene, main chain contains polarity chlorine atom, so its consistency with EVA is better than other rubber.
2) because chlorinated polyethylene rubber is to be made by poly chlorination characteristic, polyethylene and chlorine source are abundant, technology is simple, therefore its price is low, and be subjected to the influence of fluctuations of oil market price big unlike other synthetic rubber, therefore price is steady relatively, substitutes other rubber modifiers of part raising product competitiveness that can reduce cost with it.
3) because chlorinated polyethylene rubber contains the chlorine atom, thereby the weather resisteant of chlorinatedpolyethylene, ozone resistance, heat-proof aging and flame retardant resistance are all very good, the above-mentioned performance of the EVA microcellular foam material after the modification is improved.
