Embodiment 1

[0029] 1) Preparation of R-Br (R is citronellyl):

[0030] Dissolve 5mL of citronellol and 2mL of phosphorus tribromide in 30mL of anhydrous ether respectively, add aminooligosaccharin solution and 0.45mL of pyridine into a three-necked flask, stir rapidly under ice-salt bath conditions, and then add tribromide Phosphate solution was slowly added dropwise to the above reaction system. After the dropwise addition, continued to stir rapidly for 45 minutes, and then washed with 5% sodium bicarbonate solution, deionized water and saturated saline for 3 times, and dried by adding anhydrous magnesium sulfate. , filtered through a 0.22um membrane filter, and concentrated by rotary evaporation at 35°C for 30min to obtain a light yellow oily liquid citronellyl bromide.

[0031] 2) Preparation of amino oligosaccharin-ROH derivatives (R is citronellyl):

[0032] After dissolving 1g of amino oligosaccharin and 2mL of citronellyl bromide in dimethyl sulfoxide and dimethyl formamide respec...

Abstract

The mildew-proof composite elastomer comprises a porous elastomer body and silica gel composite layers, the silica gel composite layers are attached to the inner surface and the outer surface of the porous elastomer body, and each silica gel composite layer is specifically composed of a silicon-containing substrate, a curing agent and a mildew-proof agent; the invention also provides a preparation method of the mildew-proof composite elastomer. The mildew-proof composite elastomer disclosed by the invention has the advantages of good heat resistance, non-stickiness, good buffer resilience, difficulty in deformation, good air permeability, antibacterial property, mildew resistance, strong tear resistance and long service life; according to the invention, the silica gel composite layer is combined with polyurethane sponge, latex sponge, seaweed sponge and the like or other objects with three-dimensional net structures, such as loofah sponge, so that the silica gel composite layer has an excellent decontamination function in a scrubbing process, and can still keep good antibacterial and mildew-proof effects in a high-temperature and high-humidity environment; and after repeated use, the non-adhesion and non-deformation can still be kept.

Description

technical field [0001] The invention belongs to the technical field of elastomer preparation, and in particular relates to a mold-proof composite elastomer and a preparation method thereof. Background technique [0002] Ordinary cleaning sponges are made of polyurethane foam. They are not temperature-resistant, easy to deform, and oil stains are not easy to remove. They are easy to breed bacteria and have a short service life. With the provision of people's living standards, the requirements for quality of life are also getting higher and higher. Especially in the kitchen, food is not only a solution to food and clothing, but also the pursuit and enjoyment of the color, fragrance and taste of food. At the same time, we also have higher and higher requirements in terms of kitchen cleaning. For example, cleaning of dishes, cleaning of dining tables and countertops, and cleaning of other kitchen utensils, these aspects are increasingly facing more and higher requirements from...
