Bacteriostatic softener

Abstract

The invention discloses a bacteriostatic softener which comprises the following components in percentage by mass: 20-30% of chlorohydrocarbyl functional group silane, 4-6% of quaternary ammonium salt, 11-15% of methyl sulfate, 0.5-2% of a bacteriostatic agent, 0.2-1% of a preservative, 0.5-1% of an organic silicon defoaming agent and the balance of deionized water. The antibacterial softener provided by the invention can make a polymer positively charged, and the polymer can be easily adsorbed by various electronegative bacteria and viruses, so that the division function of the bacteria and viruses is inhibited, and the bacteria and viruses lose the reproductive capacity. Therefore, peculiar smell generated by bacterial reproduction is inhibited, and clothes are kept fresh in smell.

Description

Technical Field

[0001] The invention belongs to the technical field of softeners, and in particular relates to an antibacterial softener. Background Art

[0002] Single clothing cleaning only has the effect of cleaning clothes, and its single function can no longer meet people's needs. In order to meet the multi-functional needs of clothing, softeners are increasingly used. The use of softeners can solve the troubles caused by static electricity, and can also have the functions of deodorization, color preservation, wrinkle removal, and softening clothes. There are many varieties of fabric softeners available at present, but the performance varies. There are high, medium, and low efficiency, poor stability, toxic, corrosive, and irritating odors, poor softness and fluffy effect after disinfection and washing, harm to high-grade fabrics, certain damage to the skin, and certain pollution to the environment. The fabric cannot be guaranteed to be sterile after washing.

[0003] In order to solve the above technical problems, antibacterial fabric softeners have emerged, which can be used for high-end, washable clothing such as wool, silk and high-grade blended fabrics to soften after antibacterial disinfection and washing. However, the softeners on the market have poor stability, cannot work for a long time, cannot inhibit the odor caused by bacterial growth, and cannot keep the clothes smell fresh. Summary of the invention

[0004] The present invention aims at solving the above problems, improves the existing softener formula, and provides an antibacterial softener with good stability and excellent antibacterial softening effect. In order to achieve this purpose, the technical solution provided by the present invention is as follows:

[0005] In a first aspect of the present invention, an antibacterial softener is provided, the components and mass percentages of which are as follows: 20% to 30% of chloroalkyl functional silane, 4% to 6% of quaternary ammonium salt, 11% to 15% of methyl sulfate, 0.5% to 2% of antibacterial agent, 0.2% to 1% of preservative, 0.5% to 1% of organosilicon defoaming agent, and the balance is deionized water.

[0006] Preferably, the chlorohydrocarbyl functional silane is chloropropyltrimethoxysilane.

[0007] Preferably, the quaternary ammonium salt is selected from any one of diester quaternary ammonium salt, imidazoline quaternary ammonium salt or dialkyl dimethyl quaternary ammonium salt.

[0008] Preferably, the methyl sulfate is imidazoline methyl sulfate.

[0009] Preferably, the antibacterial agent is selected from any one or more of dioctadecyl dimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride, and polyhexamethylene biguanide hydrochloride.

[0010] Preferably, the preservative is selected from at least one of methylisothiazolinone and methylchloroisothiazolinone.

[0011] Preferably, the organosilicon defoamer is selected from one or more of polyether organosilicon, silicone oil or polyether modified organosilicon defoamer.

[0012] The second aspect of the present invention provides a method for preparing the above-mentioned antibacterial softener, comprising the following steps:

[0013] (1) Add deionized water into a water phase pot and heat it to 20-40° C.; Add quaternary ammonium salt and methyl sulfate into the water phase pot and stir until they are completely dissolved to form an aqueous phase;

[0014] (2) adding chloroalkyl functional silane and organosilicon defoamer into the oil phase pot, stirring for 30 to 60 minutes at a speed of 30 to 40 rpm and heating to 40 to 55° C. to form an oil phase;

[0015] (3) Add the melted oil phase to the water phase and continue stirring for 20 to 40 minutes; cool to 35°C, add an antibacterial agent and a preservative, and stir for 20 to 40 minutes to obtain an antibacterial softener.

[0016] Due to the adoption of the above technical solution, the present invention has the following advantages and beneficial effects:

[0017] The fabric softener of the present invention adopts diester quaternary ammonium salt. Since the double long chain structure of the fabric softener contains ester bonds, the fabric softener has superior biodegradability compared with dialkyl quaternary ammonium salt, is better for the environment, and has excellent softness and antistatic properties.

[0018] The addition of antibacterial agents can make the polymer positively charged, which can be easily adsorbed by various negatively charged bacteria and viruses, thereby inhibiting the division of bacteria and viruses and making them lose their ability to reproduce. This inhibits the odor caused by bacterial reproduction and keeps the clothes smelling fresh. DETAILED DESCRIPTION
