Aqueous adhesive

Abstract

The invention relates to an aqueous adhesive which comprises the following components: carboxy styrene-butadiene latex, a tackifier, an anti-aging agent, a curing agent, an antifoaming agent, a wetting agent and water, wherein a superfine rosin modified resin is adopted as the tackifier; propyl gallate is adopted as the anti-aging agent; acetone is adopted as the curing agent; emulsified silicone oil is adopted as the antifoaming agent; fatty alcohol polyoxyethylene ether is adopted as the wetting agent. The aqueous adhesive has the advantages that a raw material for preparing the aqueous adhesive comprises the carboxy styrene-butadiene latex, and a great number of air bubbles can be generated in a preparation stirring process, so that the antifoaming agent is added into the raw material to eliminate the air bubbles and simultaneously enhance the surface activity and tension of the raw material; the emulsified silicone oil is adopted as the antifoaming agent, so that the generated air bubbles can be eliminated, formation of the air bubbles can also be suppressed, and the bonding strength of the prepared adhesive is strengthened.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based adhesive. Background technique [0002] At present, my country's rubber hose products are developing rapidly, but most of the bonding between the hose rubber layer and the fabric skeleton layer has been using solvent-based adhesives that use benzene, toluene, gasoline, etc. as organic solvents, which have the advantage of high bonding strength. , The drying speed is fast, but the disadvantage is that it is highly toxic, pollutes the environment, easily causes fires, and the operation process is dangerous. Although common water-based adhesives are non-toxic, non-polluting, and highly safe, their bonding performance is poor and their bonding strength is not high. At present, the selection of raw materials for the preparation of water-based adhesives in the prior art is unreasonable, resulting in a large number of air bubbles during the preparation process, which seriously reduces the bo...

[0002] At present, my country's rubber hose products are developing rapidly, but most of the bonding between the hose rubber layer and the fabric skeleton layer has been using solvent-based adhesives that use benzene, toluene, gasoline, etc. as organic solvents, which have the advantage of high bonding strength. , the drying speed is fast, but the disadvantage is that it is highly toxic, pollutes the environment, is easy to cause fire, and the operation process is dangerous

Although ordinary water-based adhesives are non-toxic, non-polluting, and highly safe, they have poor bonding performance and low bonding strength.

At present, the selection of raw materials for the preparation of water-based adhesives in the prior art is unreasonable, resulting in a large number of air bubbles during the preparation process, which seriously reduces the bonding strength of the adhesive. Therefore, it is urgent to develop a water-based adhesive with high bonding strength. Retrieval, no technical solutions identical or similar to the present invention were found
