Problems solved by technology

Although the latex has good tensile strength properties after bonding, which can reach about 200N, however, due to its poor performance in antibacterial properties, it is prone to problems of pollution and poor corrosion resistance or reduced cohesive force.

Embodiment 1

[0023] This anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue is mainly made of the following raw materials in mass percentage:

[0024] VAc monomer: 50wt%; Alkylphenol polyoxyethylene ether: 3.0wt%; Potassium persulfate: 0.2wt%; Diethylene glycol dibenzoate: 3.0wt%; Dibutyl-4-isothiolin-3-one: 5.0wt%; film-forming aid dibutyl maleate: 1.0wt%; bispyridinethione: 0.02wt%; the balance is water.

[0025] The specific preparation method of this anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue is as follows:

[0026] Weigh the raw materials according to the mass percentage ratio of the above raw materials, first add the emulsifier, VAc monomer and water into the reactor, and after the temperature is raised to 70°C, dissolve the initiator potassium persulfate or ammonium persulfate pre-dissolved in water The reaction is carried out dropwise. During the dropwise addition, the temperature of the reaction is controlled at about 68°C to 70°C. Af...

Embodiment 2

[0028] This anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue is mainly made of the following raw materials in mass percentage:

[0029] VAc monomer: 30wt%; Glyceryl monostearate: 2.0wt%; Potassium persulfate: 0.1wt%; Triethyl citrate: 1.2wt%; Benzisothiazolinone: 3.0wt%; Dibutyl adipate: 3.0wt%; bispyridinethione: 0.04wt%; the balance is water.

[0030] The specific preparation method of the anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue is consistent with that of Example 1, and will not be repeated here.

Embodiment 3

[0032] This anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue is mainly made of the following raw materials in mass percentage:

Abstract

The invention relates to antiseptic and anti-pollution polyvinyl acetate emulsion white glue, belongs to the technical field of adhesive materials, and aims at solving the problem of low antiseptic and anti-pollution performances caused by poor anti-bacterial performance in the prior art. The white glue is prepared through the following raw materials in percentage by mass: 30-50% of VAc monomer, 1.2-3.0% of emulsifying agent, 0.1-0.3% of initiator, 1.2-3.0% of plasticizer, 3.0-5.0% of isothiazolinone compound, 1.0-3.0% of coalescing agent, 0.02-0.04% of bispyrithione, and the balance water. The antiseptic and anti-pollution polyvinyl acetate emulsion white glue is high in sterilizing effect and high in adhering intensity.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-fouling polyvinyl acetate emulsion white glue, which belongs to the technical field of adhesive materials. Background technique [0002] PVAc is a water-based thermoplastic polymer, commonly known as white latex or white latex, which is colorless, transparent, odorless, tasteless, non-toxic and highly environmentally friendly. As an important raw material in the emulsion adhesive industry, it is widely used in latex paint manufacturing, wood processing, agricultural tool manufacturing, building decoration and coating industries. As a PVAc emulsion adhesive, it has excellent performance and is currently one of the most widely used synthetic resin emulsions, and is an important base material for water-based composite adhesives. [0003] However, in all aspects of PVAc emulsion glue preparation, there is a risk of microbial contamination in the internal and external environments, and the specific manife...
