Embodiment 1

[0052] A water-based carpet backing adhesive, in parts by mass, comprising 25 parts of water-based polyurethane-acrylate emulsion, 1 part of water-dispersible polyisocyanate, 3 parts of modified titanium dioxide, 15 parts of talcum powder, 5 parts of nanocellulose, 0.5 Parts of hydroxypropyl methylcellulose ether and 5 parts of modified casein solution.

Embodiment 2

[0054] A water-based carpet backing adhesive, in parts by mass, comprising 30 parts of water-based polyurethane-acrylate emulsion, 1.2 parts of water-dispersible polyisocyanate, 4 parts of modified titanium dioxide, 18 parts of talc, 6 parts of nanocellulose, 1 Parts of hydroxypropyl methylcellulose ether and 6 parts of modified casein solution.

Embodiment 3

[0056] A water-based carpet backing adhesive, in parts by mass, comprising 35 parts of water-based polyurethane-acrylate emulsions, 2 parts of water-dispersible polyisocyanates, 5 parts of modified titanium dioxide, 20 parts of talcum powder, 7 parts of nanocellulose, 1.5 parts Parts of hydroxypropyl methylcellulose ether and 7 parts of modified casein solution.

[0057] The water-based carpet backing adhesive prepared in Examples 1 to 3 and the existing solvent-based polyurethane adhesive are applied to indoor carpet bonding, and the indoor TVOC content is detected respectively during the drying and use of the carpet. The results are shown in the following table Show:

[0058] Table 1

[0059]

[0060] As can be seen from Table 1, compared with the existing solvent-based polyurethane adhesive, the TVOC content of the water-based carpet backing adhesive prepared by the present invention is greatly reduced, which shows that the technical solution of the present invention ca...

Abstract

The invention discloses a water-based carpet backing adhesive and a preparation method thereof. The water-based carpet backing adhesive is prepared from a water-based polyurethane-acrylate emulsion, awater dispersible polyisocyanate, modified titanium dioxide and a functional auxiliary agent. The TVOC content of the water-based carpet backing adhesive is extremely low; the release amount of indoor harmful substances can be effectively reduced from the source; the environment is protected; and human health is guaranteed.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-based carpet backing adhesive and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for environmental protection of products are also getting higher and higher. TVOC is the abbreviation of volatile organic compounds, known as the "invisible killer" of human health, and its content is an important index parameter to characterize the environmental protection level of materials. At present, the existing polyurethane adhesives are mainly solvent-based polyurethane adhesives. The adhesive components of solvent-based polyurethane adhesives are solvent-based polyurethane emulsions. Solvent-based polyurethane emulsions use volatile organic compounds (such as benzene, toluene, acetone, etc.) as solvents, and their TVOC The content is generally high. In this way, when the solvent-based polyurethane adhesi...
