Abstract

The invention discloses a method for obtaining a rubber master batch product by adding a rubber reinforcing agent through wet coprecipitation. The method comprises a component formula and a preparation technology. The wet coprecipitation method is adopted, water is used as a solvent, water, natural latex and the reinforcing agent are stirred and mixed to be uniform, preparation technologies of precipitation, dehydration and drying are carried out, and the natural rubber product or the rubber master batch product for short containing the reinforcing agent is obtained. The rubber master batch product is used for preparing tire rubber; by means of wet coprecipitation, powder can be more uniformly scattered in the rubber, the technical scheme of the dust raising defect caused by dry mixing is avoided, no pyrophyllite powder reinforcing agent needs to be added when the tire rubber is prepared, and the purposes of reducing dust pollution and relieving harm to staff health are achieved.

Description

The coprecipitated interpolation rubber reinforcing filler of a kind of wet method obtains the method for rubber master batch goods
Technical field
The present invention relates to a kind of addition means of rubber reinforcing filler, specifically refer to that the coprecipitated interpolation rubber reinforcing filler of a kind of wet method adopting the coprecipitated method of wet method to add the agent of pyrophyllite powder reinforcement body in natural rubber obtains the method for rubber master batch goods.
Background technology
The milky glue extracted from rubber tree is called for short natural rubber latex; The elasticity decorating film that natural rubber latex is formed after solidifying dry processing is called for short natural rubber;
According to the requirement of product of rubber and plastic, natural rubber with the mixing formation of other composite rubber-plastic materials for making the elastomeric material of product of rubber and plastic time need to add all kinds of strengthening agent, such as, the powder strengthening agents such as White Carbon black, talcum, calcium carbonate, agalmatolite, to improve the intensity of product of rubber and plastic;
To the elastomeric material of doughnut be made referred to as rubber for tire below; Need in rubber for tire to add a large amount of pyrophyllite powder reinforcement body agent, for improving wear resisting property and the physical strength of doughnut; Below by the agent of pyrophyllite powder reinforcement body referred to as strengthening agent; When preparing rubber for tire, prior art adopts the mixing method of dry method to add related auxiliaries and strengthening agent, dry method is mixing can produce dust from flying when adding described strengthening agent, dust pollution is caused to environment, operating mode is severe, airborne dust can cause suffering from pneumoconiosis, seriously cause harm the health of operator, in addition, the intensity of the more even then rubber item distributed in rubber due to strengthening agent is higher, be blended in equably in rubber to enable strengthening agent powder, mixing time just need extend then that airborne dust is more, exacerbates dust pollution further; Therefore, there is dust pollution in prior art, cause harm healthy problems and shortcomings.
Summary of the invention
For above-mentioned prior art Problems existing with not enough, take water as solvent, by water, natural rubber latex and strengthening agent stirring and evenly mixing, through the preparation technology of standing sedimentation, dehydration and drying, obtain natural rubber products containing strengthening agent referred to as rubber master batch goods, described rubber master batch goods are for the preparation of rubber for tire; Utilize the coprecipitated dispersity making powder in rubber of wet method more even, and avoid the technical scheme of the drawback of the mixing airborne dust of dry method, the coprecipitated interpolation rubber reinforcing filler of a kind of wet method is provided to obtain the method for rubber master batch goods, be intended to the preparation participating in rubber for tire with described rubber master batch goods, without the need to adding the agent of pyrophyllite powder reinforcement body again when making to prepare rubber for tire, reach the object reducing dust pollution, alleviate enterprise employee health of causing harm.
The object of the present invention is achieved like this: the coprecipitated interpolation rubber reinforcing filler of a kind of wet method obtains the method for rubber master batch goods, comprises component formula and preparation technology, wherein,
Described component formula is,
Natural rubber latex, 25.5%;
Strengthening agent: agalmatolite powder, granularity 5 ~ 12 microns, 15%; The component requirements of described agalmatolite powder is: SiO 2, 65 ~ 70%; Al 2o 3, 20 ~ 25%; Other surplus;
Solvent: tap water, 59.5%;
Component formula unit is weight percentage;
Described preparation technology is, wet-mixed, standing coprecipitated solidification, dehydration and drying;
Step one, wet-mixed
Solvent in component formula and natural rubber latex are dropped into successively in reactor, start is uniformly mixed, mixing speed 120 ~ 150 revs/min, stirs 5 minutes used times, obtains diluted latex; Afterwards, dropped in reactor by the strengthening agent in component formula and be uniformly mixed with described diluted latex, mixing speed is 120 ~ 150 revs/min, and stirring the used time is 25 ~ 30 minutes, obtains mixed emulsion;
Step 2, standing coprecipitated solidification
Described mixed emulsion is moved in stainless steel vessel, staticly settles, coprecipitated solidification, staticly settle 1 hour used time, obtain cured article;
Step 3, dehydration
Described cured article is put into whizzer drying dehydration, obtains filter cake;
Step 4, drying
Described filter cake is placed in baking oven dry, bake out temperature is 90 ~ 100 DEG C, dries 2 hours used times, obtains the natural rubber products containing the agent of pyrophyllite powder reinforcement body, i.e. rubber master batch goods.
Principle of work and beneficial effect
Utilize natural rubber latex can dilution molten with aqueous phase, diluted latex can the coprecipitated principle of wet method of coprecipitated solidification after adhering to powder in water, reach following effect: the coprecipitated dispersity making powder in rubber of wet method is more even, better to the reinforcing effect of rubber item, turn avoid the drawback of the mixing airborne dust of dry method simultaneously, therefore, the rubber master batch goods obtained with the present invention participate in preparing rubber for tire, making the preparation of rubber for tire without the need to adding the agent of pyrophyllite powder reinforcement body again, decreasing dust pollution, alleviating causing harm to enterprise employee health.
Above-mentioned, the method that the present invention adopts wet method coprecipitated take water as solvent, by water, natural rubber latex and strengthening agent stirring and evenly mixing, through the preparation technology of standing sedimentation, dehydration and drying, obtain natural rubber products containing strengthening agent referred to as rubber master batch goods, described rubber master batch goods are for the preparation of rubber for tire; Utilize the coprecipitated dispersity making powder in rubber of wet method more even, and avoid the technical scheme of the drawback of the mixing airborne dust of dry method, the coprecipitated interpolation rubber reinforcing filler of a kind of wet method is provided to obtain the method for rubber master batch goods, overcome prior art and there is dust pollution, cause harm healthy problems and shortcomings, the preparation of rubber for tire is participated in described rubber master batch goods, without the need to adding the agent of pyrophyllite powder reinforcement body again when making to prepare rubber for tire, reach the object reducing dust pollution, alleviate enterprise employee health of causing harm.
