preparation example 1

[0046] 1) Reaction of octadecyl dimethyl tertiary amine with epichlorohydrin and hydrochloric acid:

[0047] The dry hydrogen chloride gas was introduced into the anhydrous ether solution of octadecyldimethyl tertiary amine to produce white precipitate. Then use water as the solvent, put a certain amount of epichlorohydrin in the dropping funnel, start to drop it slowly, drop it in 35 minutes, stir evenly at room temperature, react at 80°C for 12h, and titrate the epichlorohydrin quaternary ammonium After the reaction was completed, the solvent was removed by rotary evaporation at room temperature to obtain a light yellow paste residue, which was recrystallized with acetone, filtered under reduced pressure after the crystals were precipitated, and repeated several times. Obtain white powder single quaternary ammonium salt product---intermediate product N-(3-chloro-2-hydroxypropyl)-N,N-dimethyl octadecyl ammonium chloride.

[0049] 2) Reaction process: Methyl oleat...

preparation example 2

[0057] Same as Preparation Example 1, the only difference is that in the 1) step, anhydrous diethyl ether solution of dodecyldimethyl tertiary amine is used to finally obtain 2-triethoxysilyl propaneoxy-1-N,N -Dimethyloleoyl-3-dodecyldimethylammonium propane dichloride (abbreviation: organosilicon bisquaternary ammonium salt B), the yield is 98.5%.

Embodiment 1

[0060] The preparation method of the wet wipe body is as follows:

[0061] (1) Using bamboo pulp fibers with a length of 40mm and a diameter of 0.08mm as raw materials, a bamboo pulp non-woven fabric is obtained after cross-lapping and spunlace technology, and a non-woven fabric carrier with a thickness of 3mm is obtained after cutting and high-temperature sterilization ;

[0062] (2) Place the non-woven fabric carrier prepared in step (1) in the monomer solution configured by isopropanol / water mixed solvent, and soak it in the dark at room temperature for 24 hours, wherein the mass of the monomer in the monomer solution The fraction is 0.5%, and the volume ratio of isopropanol to water is 3:1;

[0063] (3) Under the protection of nitrogen, irradiate the non-woven fabric obtained after soaking in the above step (2) with gamma rays, and the irradiation intensity is 200KGy;

[0064] (4) After the irradiation is finished, unreacted monomers and homopolymers are extracted and dr...

Abstract

The invention provides a physical antibacterial wet wipe. The physical antibacterial wet wipe comprises a wet wipe body and wet wipe liquid, wherein the wet wipe body is a non-woven fabric bonded with macromolecular quaternary ammonium salt; the wet wipe liquid is prepared from RO (Reverse Osmosis) purified water, a surfactant, an emollient, a humectant, a skin conditioning agent and other additives; ozone with the concentration of 0.1mg/L to 1.0mg/L is introduced into the wet wipe liquid; finally, the wet wipe liquid is added into the wet wipe body according to a certain weight ratio and the wet wipe body is sealed and packaged to form the physical antibacterial wet wipe. The product belongs to a wet wipe with zero preservative separation; the physical antibacterial wet wipe is soft to skins, has no irritation and no allergies and is especially suitable for sensitive skins, tender skins and the like.

Description

technical field [0001] The invention relates to a physical antibacterial wet tissue, in particular to a baby buttock wet tissue. Background technique [0002] In recent years, because the application of wet wipes has brought convenience to people's lives and has gradually become a necessity in people's lives, the annual output and consumption of wet wipes have grown rapidly, and the application fields of wet wipes have continued to expand , the corresponding product development requirements are getting higher and higher. At present, there are many types of wet wipes, such as hand and mouth wipes, sanitary wipes, makeup remover wipes, skin cleansing wipes, etc. With the continuous expansion of the market scale, the national industrial policy encourages the wet wipe industry to move towards high-tech and high value-added The development of product direction will improve product competitiveness and market share, so the development of wet wipe formulation technology will play a...
