Embodiment 1

[0071] Biomass soybean gum preparation: Add 3g of alkali and 100g of water into a three-necked round bottom flask, the alkali is sodium hydroxide, stir for 3 minutes to dissolve the sodium hydroxide, and then add 0.5g silicate, 0.5 g sulfite and 0.2g modifier, the silicate is sodium silicate, the modifier is urea, and the sulfite is sodium sulfite, and stirred for 3 minutes at a temperature of 80-96 °C to obtain a preliminary mixed solution; then add 15 g of soybean derivative, which is soybean protein isolate, to the preliminary mixed solution, stir for 10 minutes at a temperature of 80°C, so that the soybean protein isolate is fully dispersed in the solution, Obtain a mixed solution; then add 0.3g of the curing agent polyamide polyamine-epichlorohydrin (PAE) aqueous solution with a mass concentration of 12.5% ​​and stir for 10 minutes to obtain a solidified mixed solution; then add the acid, the acid is 0.1 Phosphoric acid with a mass concentration of 35%, stirred for 5 minut...

Embodiment 2

[0099] Biomass soy gum preparation: Add 8g alkali and 100g water into a three-necked round bottom flask. The alkali is sodium hydroxide. Stir for 10 minutes to dissolve the sodium hydroxide. Then add 3g silicate and 3g sulfite to the lye And 5g modifier, the silicate is sodium silicate, the modifier is urea, and the sulfite is sodium sulfite, and stirred for 10 minutes at a temperature of 96°C to obtain a preliminary mixed solution; then add to the preliminary mixed solution Add 40g of soy derivative, which is soy protein isolate, stir for 60 minutes at 96℃, so that the soy protein isolate is fully dispersed in the solution to obtain a mixed solution; then add 2.5g of curing agent with a mass concentration of 12.5% Aqueous solution of polyamide polyamine-epichlorohydrin (PAE) was stirred for 60 minutes to obtain a solidified mixture; then acid was added. The acid was 4g of phosphoric acid with a mass concentration of 35% and stirred for 10 minutes to obtain a pH value of 8. Adj...

Abstract

The invention relates to a photocatalyst flame-retardant antibacterial floor and belongs to the field of functional environment-friendly health floors. The floor has a formaldehyde release limit less than 0.3 mg / L, an antibacterial rate not less than 90%, and surface wear resistance not less than 0.08 g / 100r. A base layer is a flame-retardant directional chipboard layer, comprising upper and lower surface layers of glue-mixed shavings, a core shaving layer, a first flame-retardant layer and a second flame-retardant layer; a decorative layer, a wear-resistant undercoat layer and a photocatalyst antibacterial oil facing layer are disposed in order above the base layer; a balance layer is disposed below the base layer. A production process of the floor comprises chipboard layer regulating; glue mixing; first gluing and assembly; first cold pressing; core dressing; second gluing and assembly; second cold pressing; first hot pressing; fixed thickness sanding; edging; puttying; polishing; sorting; curing; gluing and facing; third cold pressing; second hot pressing; multi-piece sawing; sanding; double end milling; undercoating; top coat blending; top-coating. The composite floor has high antibacterial performance, high strength, good wear resistance and good foot comfort.

Description

Technical field [0001] The invention relates to a photocatalyst flame-retardant antibacterial floor, which belongs to the field of functional environmentally friendly healthy floors. Background technique [0002] There are various volatile organic compounds and harmful microorganisms in people's living environment, which directly affect people's physical and mental health. Most of the pathogenic bacteria in the room environment often come from the ground dirt and pets. The floor is in direct contact with the human body, and it is easier to transmit the microorganisms that breed pathogens and bacteria to the human body. In the past, people used chemical drugs to spray anti-mildew and antibacterial agents around the room to solve the air quality problem in the room. Ordinary anti-mildew and antibacterial agents are more toxic, have poor heat resistance and durability, and are sprayed on the floor and decoration The surface of the board is easy to change color and affect the appear...
