Abstract
Detailed superiority and the manufacture method of introducing utility model rubber tyre separating releasing agent of this paper.This agent is applicable in the tire production process, the demoulding of isolation between the sizing material and sizing material and mould, effect is good, easy to use, pollution-free, safe and reliable, make simply, with low cost, the principal character and the physical chemistry essence of this technology have also been done bright and clear elaboration, and point out that this novel tire separating releasing agent than the superior part of silicone oil, is well suited for tire plant and makes use voluntarily.
Description
This agent is applicable in the rubber tyre manufacture process, between the sizing material or the isolation between sizing material and the mould and the demoulding.
Go through the isolation and the release materials of usefulness, solid powders such as potter's clay powder, talcum powder, mica, kaolin powder class are arranged, because of it is not easy to the enforcement that applies thin layer or influence next process, or the sizing material composition influenced to some extent, or influential to formed product, cause the isolating film as demolding film technology of tyre industry to eliminate use gradually to solid powder material.And then the fluent material that uses has mineral oil, oil emulsion, liquid soap, because they have the vadose solution effect or mould is had corrosiveness sizing material, or are not easy to paint thin layer, is not desirable isolating film as demolding film material therefore.
Behind the isolating film as demolding film process materials of making rubber industry with silicone oil, most of tire plant are all used it.In present domestic and international most of tire process, silicone oil is all used in the demoulding of the isolation of sizing material and sizing material and sizing material and mould.The craft book of general tire manufacturing all generally note have on silicone oil as the isolating film as demolding film material.
The use of silicone oil, its advantage are that the isolating film as demolding film performance is good, and mould is not had corrosiveness.But silicone oil is expensive material.Domestic present price is about 35 yuan of per kilograms, and tyre industry is very expensive.Use also inconvenience, Guilin tire plant with one of China tire fixed point factory is an example, claim according to this engineering department of factory, it is extremely difficult that this factory uses the working condition of silicone oil, for the ease of the brushing film forming of silicone oil, at present, need silicone oil is diluted with organic solvent (this factory uses gasoline), increased dilution operation and labor intensive, material resources, because with an organic solvent, brought pollution and inflammable easily fried disaster factors to workshop condition.From actual production situation, the tire manufacturing with silicone oil as separating releasing agent, unsatisfactory.
After silicone oil, through machining, milling treatment of colloid is made silicone emulsion to people's research with silicone oil and water, emulsifying agent etc.Owing to make raw material with silicone oil and emulsifying agent, processing equipment is accurate expensive, and silicone emulsion has only minority producer to make, and price is at per kilogram more than 13 yuan, and tire plant needs way far away buy silicone emulsion in batches, and is expensive bigger.Moreover silicone emulsion was deposited six months or towards rare back several days, the quality wild effect will occur.Because above various reasons, silicone emulsion all has inconvenience as the bigger tire separating releasing agent of consumption at aspects such as price, preservation, uses.
This practical new technology provides a kind of cheapness effective for the tire manufacturing, novel tire separating releasing agent easily again safe in utilization.
The preferred forms of present technique is, tire plant can be prepared novel separating releasing agent voluntarily, and preparing process is as follows:
Rubber tyre separating releasing agent standard recipe (weight ratio)
6 parts of montan waxes, 5 parts in soap, 120 parts in water.
Compound method:
Heat water to earlier and boil, soap is dissolved in boiling water, treat to dissolve fully, slowly wax is added, stir simultaneously.To add wax can not dissolve again till (when wax is no longer molten, can bubble through the water column and do not disperse).Cold back is with double-deck calico filtration secondary.
Equipment can be with iron pan or aluminum pot or Porcelain Jar.Stir available artificial or propeller agitation that simple motor slows down.Heating can be burnt firewood, and is all right with steam or electric heating.Equipment is very simple and easy, and the equipment tool of manpower processing usefulness is seen accompanying drawing, among the figure: 1. iron pan, 2. wooden paddle, 3. brick kitchen range.Iron pan volume=length * wide * height=1 meter * 1 meter * 1 meter, by specification processing gets final product.When using this agent, be stained with hairbrush that this agent directly is coated in sizing material or the die bush wall gets final product, also can spray.This agent manufacturing is simple, it films thin and even during use, the isolating film as demolding film effect is good, composition to sizing material does not have influence, formed product there is not influence, the next process of the processing of sizing material is implemented not have influence, mould is not had corrosiveness, environmentally safe, this agent is not fired nontoxic, safe in utilization, convenient, reliably, in addition, the most outstanding is cheap, 0.40 yuan of per kilogram cost, it is 1/88th of silicone oil cost, moreover-the good effect-tire plant of this agent can prepare voluntarily, with usefulness, needn't purchase fortune silicone oil and letting funds lie idle in batches with system far on the way.
The essence that present technique is created is to add soap to make surfactant (the general soap of this paper) and reduce surface tension greatly in water, and the particulate of montan wax is evenly spread in the water, forms constitutionally stable liquid, keep the anti-adhesion performance of wax, can evenly brush, film forming is very thin, separating releasing agent as the rubber tyre manufacturing, the isolating film as demolding film effect is good, and sizing material is not had added influence, and is pollution-free, esy to use, safe and reliable, make simply again, with low cost, good effect is fairly obvious.
(attached: as can provide in addition than the higher wax of montan wax fusing point or improve additive and other surfactants of montan wax fusing point, but this rubber tyre separating releasing agent to have reached good isolating film as demolding film effect) so not elsewhere specified (NES).

Claims (1)
- A kind of rubber tyre separating releasing agent is characterized in that:Utilize soap montan wax to be dispersed in the water: the soap of 5 parts of weight to be dissolved earlier in the water of 120 parts of weight, the wax of 6 parts of weight is slowly added to stir again and dissolve till can not be molten again as surfactant.Gained liquid can be brushed and become to approach and uniform film, keeps the anti-adhesion performance of wax, and stripping result is good, and product is easily made, and is cheap.Can replace silicone oil.
