Embodiment 1

[0020] A kind of preparation method of antibacterial flame retardant adhesive proposed by the present invention comprises the following steps:

[0021] S1, preparation modifier:

[0022] a. Wash the perilla leaves, dry them in vacuum at 40°C, crush them again, add 10 times the mass of ethanol-water mixed solvent to extract twice, each time for 2 hours, the ethanol-water mixed solvent is made from the 10:3 volume ratio of It is made by mixing water, ethanol and water. After extraction, it is filtered, and the combined filtrate is mixed solution A. The mixed solution A is concentrated under reduced pressure to half of its original volume, dried with anhydrous magnesium sulfate, and then filtered. The obtained filtrate is mixed solution A. For liquid B, concentrate the mixed liquid B under reduced pressure, dry it in vacuum at 40°C for 6 hours, grind it, and sieve it, and take the powder that passes through a 200-mesh sieve and does not pass through a 400-mesh sieve, which is per...

[0028] A kind of preparation method of antibacterial flame retardant adhesive proposed by the present invention comprises the following steps:

[0029] S1, preparation modifier:

[0030] a. Wash the perilla leaves, dry them in vacuum at 40°C, crush them again, add 10 times the mass of ethanol-water mixed solvent to extract twice, each time for 2 hours, and the ethanol-water mixed solvent is made of non-alcohol with a volume ratio of 5:1. It is made by mixing water, ethanol and water. After extraction, it is filtered, and the combined filtrate is mixed solution A. The mixed solution A is concentrated under reduced pressure to half of its original volume, dried with anhydrous magnesium sulfate, and then filtered. The obtained filtrate is mixed solution A. For solution B, concentrate the mixed solution B under reduced pressure, dry it in vacuum at 40°C for 7 hours, grind it, and sieve it, and take the powder that passes through a 200-mesh sieve but does not pass through a 400-mes...

[0036] A kind of preparation method of antibacterial flame retardant adhesive proposed by the present invention comprises the following steps:

[0037] S1, preparation modifier:

[0038] a. Wash the perilla leaves, dry them in vacuum at 40°C, crush them again, add 10 times the mass of ethanol-water mixed solvent to extract twice, each time for 2 hours, and the ethanol-water mixed solvent is made of 20:3 volume ratio It is made by mixing water, ethanol and water. After extraction, it is filtered, and the combined filtrate is mixed solution A. The mixed solution A is concentrated under reduced pressure to half of its original volume, dried with anhydrous magnesium sulfate, and then filtered. The obtained filtrate is mixed solution A. For liquid B, concentrate the mixed liquid B under reduced pressure, dry it in vacuum at 40°C for 8 hours, grind it, and sieve it, and take the powder that passes through a 200-mesh sieve but does not pass through a 400-mesh sieve, which is perilla ...

Abstract

The invention provides a preparation method of an antibacterial flame-retardant adhesive. The preparation method comprises the following steps: S1, preparing a modifier: a, treating folium perillae and screening the mesh number of perillae powder; b, mixing isoxadifen-ethyl, 1,8-naphthalic anhydride, sodium 6-hydroxynaphthalene-2-sulfonate and chitosan, adding diethyl ether, performing ultrasonicdispersion, and then adding the perillae powder and stirring to obtain the modifier; S2, performing primary modification on peanut bran: mixing the peanut bran with water, sterilizing, regulating pH value, adding lipase, the modifier and neutral protease, and performing treatment; and S3, mechanically stirring the primarily modified peanut bran, water, a dispersing agent NNO, borax and a compoundsurfactant to obtain the antibacterial flame-retardant adhesive. The preparation method provided by the invention has the advantages of rich raw material sources, low cost, simple preparation processand easiness for industrial production, and the prepared adhesive has excellent stability, fire resistance, antibacterial activity and cohesive property, long service life, and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a preparation method of an antibacterial and flame-retardant adhesive. Background technique [0002] Adhesive refers to a kind of organic or inorganic, natural or synthetic substance that can connect the same kind or two or more homogeneous or heterogeneous parts (or materials) together, and has sufficient strength after curing. . With the development of modern science and technology, adhesives, as a new type of connecting material, are being used in more and more fields, and their varieties are also increasing. Traditional adhesives are mainly made of resin and rubber substances. These adhesives have good cohesive force and strong product functionality, but they usually release formaldehyde during use, which is not friendly to the environment. Moreover, traditional adhesives are easy to burn, and when used in cartons, wooden boxes, floors and other fields, they will fuel the...
