Water-based adhesive

Abstract

The invention discloses a water-based adhesive which comprises the following components in parts by mass: 0.5-0.7 parts of water-based neoprene latex, 0.3-0.5 parts of acrylic latex, 0.001-0.005 parts of stabilizing agent, 0.001-0.002 parts of antioxidant and 0.03-0.08 parts of nanosilicon dioxide dispersing liquid. The water-based adhesive is excellent in stability, and is not required to be stirred and mixed before use. Compared with the ordinary product, the adhesive power per unit solid content is improved significantly. Superior performance can be obtained by single-sided adhesive spraying under the equivalent occasion. The adhesive effect is particularly good for a base material with a high surface opening degree. The double-sided adhesive spraying contributes to ensuring the comprehensive effect under the occasion with tension, bounce and stress, adhesion can be conducted after a moment according to the different base materials, and the pressure application and adhesion can also be conducted immediately.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based adhesive. Background technique [0002] There are several types of water-based neoprene system adhesives currently on the market: 1) Single-component water-based neoprene adhesive: Due to the characteristics of neoprene latex, this type of adhesive has slow initial viscosity and slow drying time. Not heat-resistant, poor water resistance, the advantage is that the price is low. This type of water-based neoprene adhesive is suitable for low-end applications and is not suitable for most processes. 2) Acrylic neoprene composite adhesive: After adding acrylic emulsion, although the initial adhesion and heat resistance are partially improved, due to the difference in the ion system of the two systems, the product has poor stability and is easy to break. At present, most domestic manufacturers produce this type of water-based adhesive. 3) Two-component water-based chloroprene: It adopts ...

This type of water-based neoprene adhesive is suitable for low-end applications and is not suitable for most processes

2) Acrylic neoprene composite adhesive: After adding acrylic emulsion, although the initial adhesion and heat resistance are partially improved, due to the difference in the ion system of the two systems, the product has poor stability and is easy to break.

But the disadvantage is that there is no problem of changing the heat resistance and water resistance of the chloroprene system, and at the same time it brings inconvenience to the use of the product
