[0023] A preparation method for paper pulp glue remover, the preparation method comprises the steps:

[0024] (1) Put the rotten straw into a pulverizer and crush it, pass through a 10-30 mesh sieve to obtain the sieved material, put the sieved material and liquid medium into a fermenter according to the mass ratio of 1:3-4, and seal it , and stored at a temperature of 25-30°C for 2-3 days to ferment for 2-3 days to obtain a fermentation broth, dip the inoculation loop into the fermentation broth to obtain a dipped inoculation loop, and place the dipped inoculation loop in a solid medium Streak the line to get the solid culture medium after the marking, put the solid medium after the marking into the vacuum dryer, and cultivate it at a vacuum degree of 0.01~0.03MPa and a temperature of 28~30℃ to obtain a single colony. Ratio 1: 3~4, put the single colony and liquid culture medium into the fermenter and seal it, and ferment at 25~30°C for 2~3 days to obtain the fermented liquid...

example 1

[0029] Rotten rice straw is mixed with rice straw and 1.0mol / L sodium hydroxide according to the mass ratio of 1:3, soaked for 7 hours, filtered to obtain filter residue, washed filter residue with water to obtain washed filter residue, and washed filter residue at temperature Dried at 50°C to obtain dry matter, that is, rotten straw.

[0030] The liquid culture medium is calculated in parts by weight, get 20 parts of water, 5 parts of cellulose powder, 1.2 parts of Na 2 HPO 4 ·7H 2 O, 1 part of sodium nitrate, 0.9 part of KH 2 PO 4, 0.5 parts of MgSO 4 ·7H 2 0, 0.5 part of potassium chloride, 0.5 part of yeast extract, 0.5 part of hydrolyzed casein are mixed evenly, and sterilized at high temperature to obtain a liquid medium.

[0031] Solid culture medium is by weight, get 20 parts of water, 5 parts of cellulose powder, 7 parts of agar, 1.2 parts of Na 2 HPO 4 ·7H 2 O, 1 part of sodium nitrate, 0.9 part of KH 2 PO 4 , 0.5 parts of MgSO 4 ·7H 2 0, 0.5 part of pot...

example 2

[0039] Rotten rice straw is mixed with rice straw and 1.0mol / L sodium hydroxide according to the mass ratio of 1:3, soaked for 7.5h, filtered to obtain filter residue, washed with water to obtain washed filter residue, and washed filter residue in Dry at a temperature of 55° C. to obtain a dried product, that is, rotten straw.

[0040] The liquid medium is calculated in parts by weight, get 30 parts of water, 10 parts of cellulose powder, 2 parts of Na 2 HPO 4 ·7H 2 O, 2 parts of sodium nitrate, 1 part of KH 2 PO 4 , 0.8 parts of MgSO 4 ·7H 2 0, 0.8 part of potassium chloride, 0.8 part of yeast extract, and 0.8 part of hydrolyzed casein are mixed evenly, and sterilized at high temperature to obtain a liquid medium.

[0041] Solid culture medium is by weight, get 30 parts of water, 10 parts of cellulose powder, 8 parts of agar, 2 parts of Na 2 HPO 4 ·7H 2 O, 2 parts of sodium nitrate, 1 part of KH 2 PO 4 , 0.8 parts of MgSO 4 ·7H 2 O, 0.8 part of potassium chloride...

Abstract

Belonging to the field of cleaning agents, the invention discloses a preparation method of a paper pulp adhesive removal agent. Specifically, a strain capable of degrading cellulose is extracted fromrotten straw, and fermentation is carried out to form degraded cellulose, thus improving the cleaning effect. Then chitosan, acetic acid, acetone and glycerin are mixed to reach bactericidal and bacteriostatic effects. At the same time, as chitosan has adsorption properties, a silane coupling agent can be adsorbed, also the silane coupling agent is utilized to modify cellulose in the paper pulp, and a group with amino is introduced to the cellulose surface hydroxyl position, the formation of hydrogen bond on the cellulose surface can be reduced, also the particle dispersity can be improved through the steric-hinerance effect, thereby enhancing the paper pulp wettability. The method provided by the invention solves the problems that existing organic solvent adhesive removal agents mostly contain dichloromethane, benzene and ether substances, and have high toxicity, unsatisfactory cleaning effect, and serious environmental pollution.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to a preparation method of a paper pulp glue remover. Background technique [0002] The glue remover can remove organic glue, glass glue, double-sided tape, self-adhesive, blister glue, soft glue, acrylic resin glue, epoxy resin glue, polyurethane glue, etc. The product consumption is less, and the degumming is fast. [0003] The wild advertisements in every city are overwhelming, and the dirt formed by these stickers and oil-based pens is extremely difficult to clean, which is vividly called "urban psoriasis". These small advertisements (mostly those that are illegally printed, distributed, posted, sprayed) are difficult to completely clean up, difficult to root out, very detrimental to the appearance of the city, and belong to urban garbage. The Beijing police launched a special campaign to crack down on illegal small advertisements and seized more than 4,000 people wh...
