[0030] Preparation of modified reaction solution: by weight, weigh 13 parts of 4-methylbenzoic acid, 23 parts of thionyl chloride and 0.3 part of N,N-dimethylformamide into a three-necked flask, and put the three-necked flask Place in a water bath with a water bath temperature of 60°C, mix and stir with a stirrer at a speed of 400r / min for 4h to prepare a reaction solution;
[0031] Put the above reaction solution and thionyl chloride into a four-necked flask with a condensing reflux tube at a mass ratio of 3:5, place the beaker in a water bath with a water bath temperature of 90°C, and put a magnetic rotor into the four-necked flask. The beads were condensed and refluxed for 5 hours under the condition of a magnetic rotation speed of 500r / min to obtain a reaction product. The reaction product was placed in a vacuum drying oven and dried under the conditions of a vacuum degree of 80Pa and a temperature of 65°C to obtain a dry product ;
[0032] Put chitosan and methanesulfoni...

Abstract
The invention relates to a preparation method of a corrosion-resistant high-strength anti-slip mat, which belongs to the technical field of plastic materials. The present invention utilizes 4-methylbenzoic acid and thionyl chloride to prepare methoxybenzoyl chloride phenyladipyl chloride, and then utilizes methoxybenzoyl chloride phenyladipyl chloride and thionyl chloride with shell Polycan reacts, grafts onto chitosan molecules by hydroxylation reaction, modifies chitosan to introduce amides and sulfone compounds into its molecules, and uses phenyl and other organic groups to strengthen the cross-linking between molecules Density and spatial structure can effectively improve the mechanical properties of the anti-slip mat. The invention mixes rice husk with modified chitosan, uses high temperature and high pressure and cellulase enzymatic hydrolysis to decompose rice husk to obtain cellulose, and peels off plant fibers. High temperature and high pressure make the surface of cellulose and plant fibers have hydroxyl, carboxyl and other epoxy groups, improve the dispersion effect of chitosan molecules in anti-slip mats, and have broad application prospects.
Description
technical field [0001] The invention relates to a preparation method of a corrosion-resistant high-strength anti-slip mat, which belongs to the technical field of plastic materials. Background technique [0002] There are many kinds of anti-slip mats, mainly car anti-slip mats, bathroom anti-slip mats, hotel anti-slip mats, floor mats, door mats, stair anti-slip mats, yoga anti-slip mats, carpet anti-slip mats, toolbox anti-slip mats, etc. Anti-slip mats can be divided into: rubber anti-slip mats, PVC anti-slip mats, PU anti-slip mats, AB rubber anti-slip mats, silicone anti-slip mats, magic glue anti-slip mats and so on.
