Problems solved by technology

[0006] In the above technical cases, the bonding performance of the emulsion adhesive has been improved to a certain extent through the blending modification measures, but it cannot meet the requirements for the fast bonding performance and bonding work efficiency of the emulsion adhesive. limited range
[0007] For practical applications, emulsion-type adhesives that use water as a solvent generally have problems such as slow water volatilization and low production efficiency.
Most of the current solutions are to add a pre-baking process to the sizing process to increase the surface-drying speed of the emulsion, but the adaptability of the pre-baking scheme is limited, which increases the production process and increases the production cost.

preparation example Construction

[0033] The preparation method of fast sticky type chloroprene modified acrylic acid emulsion is according to the following steps:

[0034] (1) Mix methyl methacrylate, styrene, acrylonitrile, isooctyl acrylate, hydroxyethyl methacrylate, acrylic acid, alkylphenol ether OP9, sodium lauryl sulfate and water, and pass through a homogenizer Emulsifying to obtain monomer emulsion B;

[0035] (2) dissolving potassium persulfate or sodium persulfate in water to obtain solution C;

[0036] (3) take by weighing 30% of the monomer emulsion quality of step (1) gained and 30% of the solution quality of step (2) gained, and chloroprene emulsion, under stirring state, add successively the In a normal-pressure reactor, react at a constant temperature of 78-90°C for 30 minutes until the emulsion shows blue light;

[0037] (4) Add dropwise the remaining part of the monomer emulsion obtained in step (1), and simultaneously supplement the remaining part of the solution obtained in step (2) syn...

Abstract

The invention belongs to the technical field of emulsion adhesives and particularly relates to a quick-sticking type modified chloride butyl acrylic emulsion as well as a preparation method and an application thereof. The emulsion is prepared from the following components in parts by mass: 0-20 parts of chloride butyl emulsion, 0-30 parts of methyl methacrylate, 0-30 parts of styrene, 0-30 parts of acrylonitrile, 250-300 parts of ethylhexyl acrylate, 1-2.5 parts of hydroxyethyl methylacrylate, 2-10 parts of acrylic acid, 1-6 parts of alkylphenol ether OP, 2-8 parts of lauryl sodium sulfate, 300-400 parts of water, 3-8 parts of potassium persulfate or sodium persulfate, wherein the solid content of the chloride butyl emulsion is 50%. The preparation method of the quick-sticking type modified chloride butyl acrylic emulsion has the advantages of being convenient and quick, relatively high in reaction efficiency, small in monomer residue and uniform in product appearance. The obtained modified chloride butyl acrylic emulsion has the advantages of being stable, quick in sticking and strong in adhesive strength, capable of meeting the comprehensive requirements of a high-performance chloride butyl acrylic emulsion adhesive.
