Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of cryogenic vulcanization rubber master batch and preparation method thereof.
Background technology
Rubber macromolecule the heating under with linking agent sulphur generation chemical reaction, the crosslinked process that becomes tridimensional network is called sulfuration.Rubber behind over cure claims cross-linked rubber.Sulfuration is last operation in the Rubber processing, the rubber item with practical value that can obtain finalizing the design.Because the heat conductivility of rubber is poor, and is very thick such as fruit product, heat will be transmitted to article center needs the long time.Adopt and high temperature vulcanizedly can shorten the operating time to a certain extent, but often cause incipient scorch occurring near the product edges of hot plate, general curing temperature is 160-180 ℃, consumes energy larger.
Rubber item needs to repair as breakage occurring, also needs to carry out spot cure.Common vulcanization can be divided into normal temperature and pressure sulfuration and high temperature hot sulfurization by temperature.
Normal temperature and pressure sulfuration is commonly called as cold-patch, mainly comes full capping by one deck semicure glue on the sticking patch and glue are bonding.Although this mode is repaired simple fast, have following shortcoming: 1. the sticking patch cost is high, is more than 5-10 times of common sticking patch; 2. the sticking patch pulling force is inadequate, produces crystallization by the main component neoprene latex in the glue and takes bonding sticking patch, only produces a small amount of sulfuration, and cross-linking density is little, so pulling force is inadequate; Sulfide stress does not have substantially, and sticking patch is fitted unreal, and some low-quality sticking patch just simply is stained with, and can not repair large wound, is only suitable for the repairing in minor cut or wound; 3. larger wound will be through twice repairing, once is to repair wound, and wound is repaired the complete sheet that subsidizes again, troublesome poeration and not firm; 4. vulcanizing glue has severe toxicity, harmful to health.
The high temperature hot sulfurization is commonly called as fire and mends, and curing temperature is in fact usually about 170 ℃ or higher.Its patching material low price.But also have certain shortcoming: 1. curing temperature is too high, surpass the critical temperature of rubber item, for example the critical temperature of tire is 125 ℃, ultra high temp can cause that rubber for tire and framework material are aging to be burnt, and can destroy the air retaining wall of tire, and repairing quality can not guarantee, and can not be used for the repairing of nylon tire and vacuum tyre, particularly high temperature vulcanized meeting causes air retaining wall to bubble to vacuum tyre, seepage gas phenomenon occurs, and the tire after it is repaired can not renovate again; 2. sulfide stress is inhomogeneous, and the outside mechanical pressure of using has pressure to pull phenomenon to rubber item, causes strength degradation, and inner giving with air bag pressed, but the expansion of air bag is limited, and some local insufficient pressure causes sticking patch to be fitted unreal; Inadequate because of sulfide stress simultaneously, cause repairing quality bad; 3. current consumption is large, and curing time is long, for example vulcanizes a tires current consumption about 15 degree; 4. equipment is heavy, the operation effort; 5. the tire after repairing can not carry out secondary to be repaired, and more can not renovate.
Summary of the invention
According to above-mentioned weak point, the purpose of this invention is to provide and a kind ofly can reduce rubber master batch of curing temperature and preparation method thereof.
Technical scheme of the present invention is: a kind of cryogenic vulcanization rubber master batch, formed by major ingredient and auxiliary material, and major ingredient is high-temp glue, secondary material is epoxy glue A and epoxy glue B; Its prescription forms
High-temp glue 15-30 part
1 part of epoxy glue A
1 part of epoxy glue B;
Wherein, the composition of epoxy glue A is by weight
The composition of epoxy glue B is by weight
A kind of preparation method of cryogenic vulcanization rubber master batch comprises the steps
1) add high-temp glue bag roller in rubber mixing machine, add epoxy glue A, behind the wedging, the dancer rools distance is less than 1mm fully, and thin-pass packs at least twice;
2) adding the rubber unvulcanizate continuation bag roller of epoxy glue A, add epoxy glue B, behind the wedging, the dancer rools distance is less than 1mm fully, and thin-pass packs at least twice;
3) roll spacing between two running rollers of adjusting, slice.
Preferably: the thickness in the described step 1 during high-temp glue bag roller is 2-4mm.
Preferably: the thickness when having added the rubber unvulcanizate bag roller of epoxy glue A in the described step 2 is 2-4mm.
The invention has the beneficial effects as follows: the present invention adds epoxy glue A and epoxy glue B according to a certain percentage in high-temp glue, do not change former high-temp glue color, the former high-temp glue physicals of basic maintenance, reduced the curing temperature of former high temperature vulcanizate, satisfied in the rubber item production process demand to low temperature glue, when rubber item is repaired, avoided simultaneously the Aging Damage of secondary high-temperature to former goods vulcanized rubber, vulcanized efficient high, energy-conservation and repair firm.
