Description
Technical Field
The invention relates to butyronitrile butadiene styrene composite latex dipping slurry in the field of latex preparation and a preparation method thereof, in particular to novel butyronitrile butadiene styrene composite latex dipping slurry and a preparation method thereof.
Background
At present, the common cold-proof rubber gloves adopt natural latex as a coating. The natural rubber has good tensile property and low temperature resistance, and the flexibility of the natural rubber is not influenced by the reduction of the air temperature. But the natural rubber has poor wear resistance and basically does not resist oil; therefore, it is not usable at low temperature and in oily environment, or has a short service life. While the general butyronitrile cold-proof rubber gloves have better oil resistance and wear resistance, the gloves are too hard to use under the low temperature condition.
In the prior art, although the nitrile rubber can maintain the use strength at low temperature, the nitrile rubber has poor toughness and is restricted to be used at low temperature, and the rubber with low temperature resistance and oil resistance has high hardness and is not suitable for the production of gloves.
In order to solve the above problems, it is important to research a nitrile latex blend material with good toughness at low temperature, because the cost of nitrile in the current market is higher and higher, and the cost is too high to bear.
Disclosure of Invention
The invention aims to provide butyronitrile butadiene styrene composite latex dipping slurry and a preparation method thereof, aiming at the defects of the prior art, the butyronitrile butadiene latex mixed material with good toughness under the low-temperature condition can be obtained.
In order to achieve the above object, the present invention provides a novel method for preparing a butyronitrile butadiene styrene composite latex dipping slurry, wherein the method comprises: step 1, weighing raw materials in proportion; step 2, adding butadiene-styrene latex into the butyronitrile latex, sequentially adding a surfactant, a vulcanizing agent, a vulcanization accelerator, an antioxidant and a low-temperature plasticizer, and uniformly stirring and mixing to obtain mixed butyronitrile butadiene-styrene latex; step 3, standing the mixed butyronitrile butadiene styrene latex obtained in the step 2 for 12-24 hours; and 4, adding a tackifier into the parked mixed butadiene-acrylonitrile butadiene-styrene latex, and uniformly mixing to obtain the butadiene-acrylonitrile butadiene-styrene latex composite material.
The novel preparation method of the butyronitrile butadiene styrene composite latex dipping slurry comprises, by mass, 30-60% of butyronitrile latex, 30-60% of butadiene styrene latex, 0.2-2% of a surfactant, 0.1-2% of a vulcanizing agent, 0.1-3% of a vulcanization accelerator, 0.5-4% of an antioxidant, 1-3% of a low-temperature plasticizer and 2-4% of a tackifier.
The novel preparation method of the butyronitrile butadiene styrene composite latex dipping slurry comprises the following steps of (1) preparing a butyronitrile butadiene styrene composite latex dipping slurry, wherein the content of acrylonitrile in the butyronitrile latex is greater than or equal to 30% by mass percent; the content of the butylbenzene in the butylbenzene latex is more than or equal to 35 percent by mass percent.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the step of preparing a composite latex dipping slurry, wherein the surfactant comprises any one or more of sodium dodecyl benzene sulfonate, sodium dodecyl sulfate, stearic acid, disodium lauryl sulfosuccinate monoester and lauryl alcohol ether phosphate.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the step of preparing a vulcanizing agent, wherein the vulcanizing agent comprises any one or more of sulfur, TMTD, dibenzoyl peroxide and dicumyl peroxide.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the step of preparing a vulcanization accelerator, wherein the vulcanization accelerator comprises any one or more of zinc diethyldithiocarbamate, dibenzothiazyl disulfide, 2-mercaptobenzothiazole and diphenylguanidine.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the step of preparing the antioxidant by using a raw material, wherein the antioxidant comprises any one or more of an antioxidant 1010, an antioxidant 2246, an antioxidant T501, an antioxidant 264 and an antioxidant 330.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the step of preparing a low-temperature plasticizer, wherein the low-temperature plasticizer comprises one or more of DOS, DOA and DBS.
The preparation method of the novel butyronitrile butadiene styrene composite latex dipping slurry comprises the following steps of (1) preparing a tackifier, wherein the tackifier comprises sodium carboxymethylcellulose and/or propylene glycol alginate; and adding a tackifier to obtain the butyronitrile butadiene styrene latex composite material with the viscosity of 300-800 MPa & s.
The invention also provides the novel butyronitrile butadiene styrene composite latex dipping slurry prepared by the method, wherein the dipping slurry is used for preparing butyronitrile gloves.
The novel butyronitrile butadiene styrene composite latex dipping slurry and the preparation method thereof provided by the invention have the following advantages:
the slurry developed by the invention and the butyronitrile material prepared by dipping the slurry have good flexibility at low temperature, have excellent wear resistance and oil resistance, and can be used for industrial production.
