Abstract

The invention discloses a modified polyacrylate flame-retardant emulsion, a modified polyacrylate flame-retardant pressure-sensitive adhesive containing the emulsion and a preparation method of the modified polyacrylate flame-retardant emulsion, and the preparation method of the modified polyacrylate flame-retardant emulsion comprises the following steps: firstly, mixing epoxy resin and acrylic acid mixed monomers, then adding an emulsifier solution for pre-emulsification to obtain a pre-emulsion, and then adding the pre-emulsion into a reaction kettle for reaction to obtain the modified polyacrylate flame-retardant pressure-sensitive adhesive. And dropwise adding an initiator solution into the pre-emulsion, and carrying out semi-continuous seed-initiated polymerization to obtain a seed emulsion, namely the modified polyacrylate flame-retardant emulsion. The modified polyacrylate emulsion has good fire resistance, and also has excellent cohesiveness, weather resistance and film-forming property of the polyacrylate emulsion. The main component of the pressure-sensitive adhesive is modified polyacrylate flame-retardant emulsion, melamine-ammonium polyphosphate-dipentaerythritol is supplemented as an intumescent flame-retardant system, and titanium dioxide, zinc oxide, graphene and diatomite are added to reduce the smoke amount and improve the strength of a carbon layer, so that the flame-retardant property of the pressure-sensitive adhesive is improved.

Description

technical field [0001] The invention relates to the technical field of flame retardant acrylic adhesives, in particular to a modified polyacrylate flame retardant emulsion and a preparation method thereof, and a modified polyacrylate flame retardant pressure-sensitive adhesive comprising the emulsion and a preparation method thereof. Background technique [0002] In recent years, the domestic demand for acrylate pressure-sensitive adhesives is increasing, and some special fields have strict requirements on its flame retardant properties. Environmentally friendly brominated flame retardants are used in existing pressure-sensitive adhesive products, but halogens themselves will cause serious harm to the human body, and the combustion of halogens will bring a large amount of toxic and harmful gases to the environment, directly or indirectly causing damage to the human body. Metabolic disorders such as nervous system, respiratory system, digestive system and circulatory system. ...
