Abstract
The invention discloses a kind of pre-dispersed resin and its application methods, are related to pre-dispersed resin art.It is unstable to solve the problems, such as that non-brominated phenolic resin is stored by the way that non-brominated phenolic resin to be first distributed in polychloroprene latex by the present invention；Zinc oxide is activating agent, while a little metal chloride can be formed with calcium chloride, has the function of promoting non-brominated phenolic resin curative efficiency；Homogenizing agent is the substance containing various active group, and suitable homogenizing agent, which is added, can make non-brominated phenolic resin, neoprene, zinc oxide be uniformly dispersed, be firmly combined to each other, and the pre-dispersed resin of preparation, which is stored, to be stablized.Compared with prior art, which stablizes, and is easily dispersed in butyl rubber, has both the effect of activating agent, vulcanizing agent, promotor, improves the stability and qualification rate of tire curing bladder batch production.
Description
Technical field
The present invention relates to pre-dispersed resin arts, and in particular to a kind of pre-dispersed resin and its application method.
Background technique
The main sizing material of tire curing bladder is butyl rubber, is considered in conjunction with composite factors such as vulcanization effect, curingprocess rates,
In the industrial production, resin curative systems are often used in tire curing bladder itself preparation.And curing resin is each vulnerable to light, heat etc.
The influence of kind of factor, stores unstable, disperses unstable in butyl rubber, and then tire curing bladder product batch is caused to be stablized
Property is not high.
Such as in the Chinese patent of Publication No. CN1043950 disclosed in 18 days July nineteen ninety, mentions and dispersing to needs
A kind of effective dispersing agent is added in resin, produces a kind of pre-dispersed resin.
Summary of the invention
To solve deficiency in the prior art, the invention discloses a kind of pre-dispersed resin and its application methods.
The technical solution adopted by the present invention is that a kind of pre-dispersed resin, component includes: non-brominated phenolic resin, neoprene rubber
Glue, zinc oxide, homogenizing agent；
Preparation process:
S1, the polychloroprene latex that metering is first added in a kettle, set temperature of reaction kettle as 45~55 DEG C, open stirring；
S2, weighed non-brominated phenolic resin, zinc oxide, homogenizing agent be added in the polychloroprene latex in S1 again, stirred
Dispersion；
S3, the calcium chloride water that configuration concentration is 1%, the polychloroprene latex in S2 is poured into calcium chloride water, after
, there is coagulative precipitation in continuous stirring；
S4, the calcium chloride water in S3 is filtered, obtains pre-dispersed resin, dried.
In the formula design of pre-dispersed resin, according to mass parts, have following proportion to refer to: 40%~50% is non-brominated
Phenolic resin, 20%~30% neoprene, 10%~25% zinc oxide, 10%~25% homogenizing agent.
The calcium chloride water configured in S3 be it is hot, on the one hand temperature can speed up neoprene at 80~100 DEG C
The coagulative precipitation of latex is reacted, and the product being on the other hand precipitated is uniform.
Application method of the pre-dispersed resin of one of present invention in tire curing bladder.Refining glue before this, by butyl rubber
Glue is added in open mill, and to sizing material packet roller, reinforced filling carbon black, plasticizer paraffin oil, pre-dispersed resin are added sequentially to out
It is thin logical multiple in mill, to be mixed uniform, extruded sheet；Then injection vulcanization, the film of extrusion is added in injector,
Curing bag is molded according to the injection sulfuration process of tire curing bladder.
The present invention solves non-brominated phenolic resin storage not by the way that non-brominated phenolic resin to be first distributed in polychloroprene latex
Stable problem；Zinc oxide is activating agent, while a little metal chloride can be formed with calcium chloride, has and promotes non-brominated phenol
The effect of urea formaldehyde curing efficiency；Homogenizing agent is the substance containing various active group, be added suitable homogenizing agent can make it is non-
Brominated phenolic resin, neoprene, zinc oxide are uniformly dispersed to each other, are firmly combined, and the pre-dispersed resin of preparation, which is stored, to be stablized.
Compared with prior art, non-brominated phenolic resin, zinc oxide, homogenizing agent are added in polychloroprene latex and are made by the present invention
Standby resin pre-dispersed out, the pre-dispersed resin property are stablized, are easily dispersed in butyl rubber, have both activating agent, vulcanizing agent,
The effect of promotor greatly increases the stability and qualification rate of tire curing bladder batch production.
