Embodiment 1

[0011] A method for synthesizing hydrophilic and antibacterial special silicone oil, comprising the steps of: putting 200kg of low-hydrogen silicone oil, 25kg of allyl epoxy polyether, 30kg of allyl alcohol and 15kg of isopropanol T into a 1000kg reactor In; the reaction kettle was heated up to 55 degrees Celsius, and 2g of chloroplatinic acid was added; the insulation was kept for 4 hours; Propylene oxide condensate or polyethylene glycol is used as an additive; react at 80°C for 6 hours to obtain a colorless or light yellow transparent hydrophilic antibacterial special silicone oil. Among them, the hydrogen content (wt%) of hydrogen-containing silicone oil is 0.1-0.3, the molecular weight of allyl epoxy polyether is 500-2000, the molecular weight of allyl alcohol is 600-1500, and the molecular formula of alkyl carboxylate is Contains 10-18 carbons.

Embodiment 2

[0013] A method for synthesizing hydrophilic and antibacterial special silicone oil, comprising the steps of: putting 200kg of low hydrogen-containing silicone oil, 200kg of allyl epoxy polyether, 240kg of allyl alcohol and 64kg of isopropanol T into a 1000kg reactor In; the reactor was warmed up to 55 degrees Celsius, and 5g of chloroplatinic acid was added; it was incubated for 6 hours; 13.5kg of alkyl carboxylate and 15kg of coupling agent were added to the reactor; it was reacted for 6 hours at 100°C to obtain a colorless or Pale yellow transparent hydrophilic antibacterial special silicone oil. Among them, the hydrogen content of hydrogen-containing silicone oil is 0.1-0.3, the molecular weight of allyl epoxy polyether is 500-2000, the molecular weight of allyl alcohol is 600-1500, and the molecular formula of alkyl carboxylate contains 10-18 carbon.

Abstract

The invention discloses a method for synthesizing hydrophilic antibacterial special silicone oil. The method comprises the following steps: preparing a mixture from 200 kg of low-hydrogen silicone oil, 25-200 kg of allyl epoxy polyether, 30-240 kg of an allyl alcohol and a certain amount of isopropyl alcohol T, and adding the mixture into a 1000 kg reaction kettle, wherein the weight of the isopropanol T is 5-10% of the total weight of the mixture; heating the reaction kettle to 55 DEG C, and adding 2-5 g of chloroplatinic acid; keeping the temperature for 3-6 h; adding 4.5-13.5 kg of alkyl carboxylate, 5-15 kg of a coupling agent and ethylene glycol monobutyl ether accounting for 0-10% of the total weight of the material in the reaction kettle into the reaction kettle; and carrying out areaction at 80-100 DEG C for 6 h to obtain the colorless or pale yellow and transparent hydrophilic antibacterial special silicone oil. The hydrophilic antibacterial special silicone oil of the invention is applied to textiles to make the textiles have good hydrophilicity, good antibacterial ability, comfortable feeling and stable wearing experience.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a method for synthesizing special hydrophilic and antibacterial silicone oil. Background technique [0002] Hydrophilic silicone oil is widely used in textiles. The silicone oil has good water solubility and is difficult to break emulsion and float oil. After being applied to the fabric, the sweat discharged from the human body can quickly penetrate into the fabric, keeping the human body with a good sense of wearing comfort. It can also play the role of dustproof and antistatic to a certain extent. Not only suitable for touch style finishing on outerwear, but also for style finishing on underwear. [0003] However, the conventional hydrophilic silicone oil does not have an antibacterial effect, and there is a possibility of bacterial growth under different conditions, causing discomfort to the skin and reducing wearing comfort.
