Embodiment 1
[0095] Embodiment 1: styrene-butadiene latex, the components included and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps:
[0096] S1, under vacuum conditions, the first solvent, divinylbenzene, anionic emulsifier, first emulsifier, hydroxyethyl cellulose, polysorbate-80, acrylic acid, N-hydroxyl Methacrylamide, acrylamide, pH regulator, and polyvinyl alcohol are mixed evenly to form an aqueous phase material;
[0097] S2, under vacuum conditions, the corresponding weight fractions of styrene, butadiene, organic solvent, and ethyl 3-mercaptobutyrate in the oil phase material are uniformly mixed to form the oil phase material;
[0098] S3, mixing the mbs seed latex, sodium dodecylbenzene sulfonate, and the second solvent of the corresponding weight fraction in the primer to form a primer;
[0099] S4, under vacuum conditions, get the third solvent in other materials, 260 parts of water phase materials obtained in step S1,...

Abstract
The invention discloses butadiene-styrene latex and a preparation method thereof. The butadiene-styrene latex is prepared from water phase materials (a first solvent, divinylbenzene, an anionic emulsifier, a first emulsifier, hydroxyl ethyl cellulose, polysorbate-80, acrylic acid, N-methylol acrylamide, acrylic amide, and a pH regulator), oil phase materials (styrene, butadiene, an organic solvent, and 3-mercaptobutyrate), base materials (mbs seed latex, sodium dodecylbenzenesulfonate and a second solvent), and other materials (a third solvent, EDTA, initiator mixture, a water-based foam suppressor, liquid base, and a second emulsifier), wherein both the first emulsifier and the second emulsifier are non-ionic emulsifiers, the first solvent, the second solvent and the third solvent are allsoft water, and the organic solvent comprises one of butyl acetate, butyl acetate, and butyl acrylate. The butadiene-styrene latex has advantages of good water resistance, aggregate stability, mechanical stability, and chemical stability.
Description
technical field [0001] The invention relates to the technical field of styrene-butadiene latex synthesis, more specifically, it relates to a styrene-butadiene latex and a preparation method thereof. Background technique [0002] SBR latex can be applied to the surface and bottom coating of papermaking decorative base paper, wear-resistant paper, medium and high-grade art paper, white board paper, cardboard, cardboard paper, etc. It can also be applied to non-woven fabrics and artificial leather And other impregnation processing. However, the existing styrene-butadiene latex usually has the phenomenon of "hot stickiness and cold brittleness", and the water resistance and stability are still not ideal. Therefore, a kind of styrene-butadiene latex with better water resistance and stability has better commercial value. Contents of the invention [0003] In view of the deficiencies in the prior art, the first object of the present invention is to provide a styrene-butadiene l...
