Abstract
The invention relates to a tire release agent, and belongs to the technical field of processing of rubber products. The tire release agent is prepared from the following materials in parts by weight: 100 parts of active organosilicon polymer, 10-30 parts of emulsifier, 10-15 parts of accelerant, 1-3 parts of catalyst, 0.1-2 parts of bactericide and 200-350 parts of deionized water. By adopting the technical scheme, the tire release agent has good chemical stability, and also has storage stability on the premise that the ideal demolding effect is not lost or not migrating towards the tire is not generated; and a crosslinked membrane layer can be rapidly formed on the surface of a mold in the presence of the catalyst to be scrapped by a sizing material and chemically eroded. Thus, the tire release agent does not migrate towards the tire, and does not pollute the mold because of agglomeration.
Description
Technical field
The invention belongs to the rubber processing technique field, be specifically related to a kind of tire releasing agent, be used in the demoulding to the compression molding of tyre forming process.
Background technology
Along with developing rapidly of Domestic Automotive Industry, the rubber tyre processing industry is development also, in order to improve the manufacturing efficient of rubber tyre, usually needs to use the tire releasing agent.
The tire releasing agent of commonly using in rubber industry is produced at present mainly contains mixed solution or emulsion and the silicone emulsion of oil, paraffin, oil and paraffin.Because silicone emulsion class releasing agent has desirable lubricity, only need to use minute quantity, excellent stripping result is just arranged, and can not absorbed by rubber, thereby mostly use at present silicone emulsion class releasing agent.Patent information such as CN101406928A, CN102199352A and US3872038 about silicone emulsion class releasing agent, yet, because these patent scheme introductions all is silicone emulsion class take water or hydro carbons as medium, thereby there are following 2 deficiencies: at first, releasing agent can move on the tire, affects tire quality; Secondly, easily produce the bad phenomenon of cohesion, pollute mould.
Based on above-mentioned prior art, the present inventor has done a large amount of further investigation work, and has made good try, below the technical scheme that will introduce based on producing under this prerequisite.
Summary of the invention
Top priority of the present invention is to provide a kind of helping avoid to move on the tire and use and guarantee tire quality and be conducive to prevent from condensing and use the tire releasing agent of avoiding mold fouling.
Top priority of the present invention is finished like this, a kind of tire releasing agent, and it is that raw material by following weight portion proportioning consists of:
100 parts in active organosilicon polymer;
Emulsifying agent 10-30 part;
Promoter 10-15 part;
Catalyst 1-3 part;
Bactericide 0.1-2 part;
Deionized water 200-350 part.
In a specific embodiment of the present invention, described active organosilicon polymer is at least two kinds in octamethylcy-clotetrasiloxane, HMDO, hydroxyl endblocked polydimethylsiloxane, the polymethyl hydrogen siloxane.
In another specific embodiment of the present invention, described emulsifying agent is one or more in sorbester p17, Tween 80, the aliphatic acid polyethenoxy ether.
In another specific embodiment of the present invention, described promoter is the aqueous silane coupling agent.
In another specific embodiment of the present invention, described catalyst is cobalt naphthenate or lead naphthenate.
Also have in the specific embodiment of the present invention, described bactericide is OIT.
Technical scheme provided by the invention has good chemical stability, is not losing desirable stripping result and can also not have storage stability under the prerequisite of tire migration; Can be fast under the effect of catalyst form the crosslinked film layer and can stand sizing material and scrape the scrape along chemical erosion at die surface, therefore can not move to tire, and can not pollute because cohesion produces mould.
