[0034] Step 1: Add 30g of maleic anhydride, 2g of dibenzoyl peroxide, and 30ml of ethyl acetate, stir for 2 hours, add 30ml of styrene; heat at 80°C for 2 hours to obtain a styrene-maleic anhydride copolymer. Add 30g of styrene-maleic anhydride copolymer and 4g of silane coupling agent KH-550; heat and react at 80°C for 2h, cool down, and perform pulse electric field treatment with a pulse frequency of 1kHz, a pulse width of 40μs, and a treatment pulse number of 30 Add absolute ethanol, filter with suction, wash, and dry in vacuum at 100°C for 2 hours to obtain a modified styrene-maleic anhydride copolymer.

[0035]Step 2: Stir soybean polysaccharide and deionized water for 3 hours, mix well, add isocyanate and ethyl acetate, stir for 3 hours, add butanediol, stir at 50°C for 1 hour, cool, wash with deionized water, filter, and dry. Obtain the isocyanate modifier; add defatted soy flour, starch, isocyanate modifier, ethyl acetate, stir for 2 hours, carry out pulse electric fie...

Embodiment 3

[0041] Step 1: Add 30g of maleic anhydride, 2g of dibenzoyl peroxide, and 30ml of ethyl acetate, stir for 3 hours, add 30ml of styrene; heat at 90°C for 3 hours to obtain a styrene-maleic anhydride copolymer. Add 30g of styrene-maleic anhydride copolymer and 4g of silane coupling agent KH-550; heat and react at 90°C for 3h, cool down, and perform pulse electric field treatment with a pulse frequency of 1kHz, a pulse width of 40μs, and a treatment pulse number of 30 Add absolute ethanol, filter with suction, wash, and dry in vacuum at 120°C for 3 hours to obtain a modified styrene-maleic anhydride copolymer.

[0042] Step 2: Stir soybean polysaccharide and deionized water for 4 hours, mix well, add isocyanate and ethyl acetate, stir for 4 hours, add butanediol, stir at 60°C for 2 hours, cool, wash with deionized water, filter, and dry. Obtain an isocyanate modifier; add defatted soybean flour, starch, isocyanate modifier, and ethyl acetate, stir for 3 hours, and perform pulse e...

Abstract

The invention discloses plant source mildew-proof wallpaper glue and a preparation method thereof. And a protein-based adhesive, monoethyl fumarate and compound essential oil are added. The modified defatted bean flour and the starch which are treated by a pulsed electric field are added into the protein-based adhesive, so that the viscosity of the wallpaper adhesive is increased, and the wallpaper adhesive has hydrophobicity; and the modified styrene-maleic anhydride copolymer treated by the pulsed electric field is added, so that the viscosity of the wallpaper adhesive is increased. Meanwhile, monoethyl fumarate is added, so that the wallpaper adhesive has mildew-proof performance. Compound essential oil including eucalyptus globulus essential oil, ginger essential oil, origanum vulgare essential oil and shepherd's purse flowering branch essential oil is further added to improve the antibacterial, mildew-proof, corrosion-resistant and insect-proof performance. The wallpaper glue prepared by the plant source mildew-proof wallpaper glue and the preparation method thereof provided by the invention has high viscosity, mildew resistance, antibacterial property, corrosion resistance and insect resistance.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to a plant-source mildew-resistant wallpaper glue and a preparation method thereof. Background technique [0002] Nowadays, environmental protection has become a hot topic in the home improvement industry. With more and more recognition of wallpaper, the importance of adhesive materials to environmental protection can no longer be ignored. Choosing a good wallpaper glue can not only guarantee the quality of the wallpaper to a large extent. Excellent viscosity, strength and appearance, to achieve smooth paste, and do not use raw materials that are highly irritating to the human body, and can meet people's high requirements for safety, comfort, health and harmlessness in decoration. [0003] However, the ordinary wallpaper glue is pasted on the wall for a long time and the wallpaper is prone to yellowing and mildew. The production and application of low-toxic wallpaper glue with good fun...
