Abstract

The invention relates to an odor-inhibiting hydrophilic soft sponge based on a silicon-phosphorus-aluminum zeolite molecular sieve and a preparation method thereof. The odor-inhibiting hydrophilic soft sponge is prepared from the following raw materials by weight: 10.9 parts of DEP-505S, 9.1 parts of universal polyether polyol, 10 parts of toluene diisocynate, 5 parts of dichloromethane, 0.5 partof organic silicone oil, 0.1 part of dimethylethanolamine, 0.1 part of stannous octoate, 5 parts of cellulose, 1 part of super absorbent resin and 1.5 parts of deionized water. The dosage of the silicon-phosphorus-aluminum zeolite molecular sieve is 1 part, the particle size is 0.5microm, and the specific surface area of the silicon-phosphorus-aluminum zeolite molecular sieve is 750m<2> / g, and acidification and surface coupling coating treatment is carried out according to the process method of: putting the silicon-phosphorus-aluminum zeolite molecular sieve into a citric acid microcapsule solution to enable the concentration of the silicon-phosphorus-aluminum zeolite molecular sieve to be 5%-20%, then carrying out ultrasonic treatment for 4-6 hours to a constant weight, and then carryingout surface coupling coating treatment by adopting a silane coupling agent containing vinyl.

Description

[0001] This application is a divisional application with application number: 201711422633.1, application date: December 25, 2017, and title of invention: a hydrophilic soft sponge and its preparation method and application. technical field [0002] The invention relates to the technical field of polymer materials, in particular to a taste-suppressing hydrophilic soft sponge based on silicon-phosphoraluminum zeolite molecular sieves and a preparation method thereof. Background technique [0003] With the improvement of people's living standards and the development of sanitary material technology, disposable sanitary products have been widely used in maternal and child care.
