Abstract

The invention discloses a high-strength water-resistant and flame-retardant plain paper and a preparation method thereof, and relates to the technical field of flame-retardant paper. The high-strength water-resistant and flame-retardant plain colored paper of the present invention uses styrene, butyl acrylate, etc. Sodium alkyl sulfate and nonylphenol polyoxyethylene ether were used as emulsifiers, persulfate was used as initiator, sodium bicarbonate was used as buffer, organically modified montmorillonite was used as modifier, and montmorillonite was synthesized by pre-emulsified seed emulsion polymerization Desoil modified functionalized styrene-acrylic latex; then compound it with flame retardants containing various flame-retardant elements to obtain flame-retardant styrene-acrylic latex, and then use the surface coating method to coat the flame-retardant styrene-acrylic latex on the The surface of plain paper base paper, just dry. The plain colored paper prepared by the invention has excellent dry and wet tensile strength, excellent water resistance and good flame retardancy, and the invention has advanced preparation technology, no pollution and low production cost, and has broad market application prospects.

Description

technical field [0001] The invention relates to the technical field of flame-retardant paper, more specifically, the invention relates to a high-strength water-resistant and flame-resistant plain paper and a preparation method thereof. Background technique [0002] The lack of global forest resources has prompted the mass production of veneers, and plain paper as a surface decoration material for veneers has become a widely used decorative material in the furniture industry and building decoration industry. With the development of society and the improvement of people's living standards, ordinary plain paper can no longer meet the requirements of veneer materials. For example, from the perspective of fire safety, plain paper used in interior decoration generally needs to be treated with flame retardant to reduce its fire hazard. Hidden dangers; from the perspective of the use of furniture, plain paper also needs water resistance, light resistance and better strength to achie...
