Problems solved by technology

Neoprene adhesives and polyurethane adhesives are widely used in the market now, which have poor bonding effect on difficult-to-bond materials such as polyethylene, polypropylene, and polyvinyl chloride, and are easily hydrolyzed and have poor weather resistance, resulting in a short service life for interior decoration.
In addition, conventional neoprene adhesives and polyurethane adhesives have poor flame and fire resistance

preparation example Construction

[0045] The present invention also provides a preparation method of a water-based environmentally friendly flame-retardant adhesive, which comprises the following steps:

[0046] Add water-based polyurethane emulsion and pH stabilizer to the reaction kettle according to the above mass parts, and stir for 10-20 minutes;

[0047] Add flame retardant and stir for 10-20 minutes;

[0048] Add anti-hydrolysis agent and stir for 10-20 minutes;

[0049] Add hydrophilic fumed silica and stir for 30-60 minutes;

[0050] Add VAE emulsion and stir for 15-20 minutes;

[0051] Add water-based tackifying resin and stir for 15-20 minutes;

[0052] Add defoamer and stir for 10-20 minutes;

[0053] Then add 0.2-0.5 parts of rheology modifier, stir evenly, and filter out the material.

[0054] In order to ensure that the aqueous fumed silica is fully and uniformly wetted and dispersed, for example, after adding the aqueous fumed silica, the silica is dispersed by shaking, mechanical stirring...

Abstract

The invention relates to a water-based environment-friendly flame-retardant adhesive, which is prepared from the following components by mass: 40-60 parts of a VAE emulsion; 5-20 parts of a flame retardant; 10-20 parts of water-based tackifying resin; 20-60 parts of a waterborne polyurethane emulsion; 6-10 parts of hydrophilic fumed silica; 1.2-3 parts of an anti-hydrolysis agent; 0.3-0.5 part of a defoaming agent; 1-3 parts of a pH stabilizer; and 0.2-0.5 part of a rheology modifier. According to the water-based environment-friendly flame-retardant adhesive, the pH stabilizer, the emulsifier, the water-based fumed silica and the like are added, and the adding sequence of all the components is adjusted, so that the waterborne polyurethane emulsion, the flame retardant and the VAE emulsion are compounded to form a stable system, therefore, the water-based environment-friendly flame-retardant adhesive has the advantages of high solid content, high drying speed, excellent performance, long opening time, high adaptability to adhesive materials, no combustibility, no corrosion and low VOC, meets the environment-friendly requirements, is convenient for operators to operate, and can effectively prevent fire disasters and occupational diseases. And the water-based environment-friendly flame-retardant adhesive can be applied to airplanes, automobiles, indoor interior decorations and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-based environmentally friendly flame-retardant adhesive and a preparation method thereof. Background technique [0002] Adhesives are widely used in automotive and aircraft interiors, and interior adhesives are required to have good flame retardancy and weather resistance. Neoprene adhesives and polyurethane adhesives are widely used in the market now, which have poor bonding effect on difficult-to-bond materials such as polyethylene, polypropylene, and polyvinyl chloride, and are easily hydrolyzed and poorly weather-resistant, resulting in a short service life of the interior. In addition, conventional neoprene adhesives and polyurethane adhesives have poor flame and fire resistance. Contents of the invention [0003] Based on this, it is necessary to address the above problems and provide a water-based adhesive with simple process, wide application range, easy oper...
