Problems solved by technology

The traditional preparation method of nano-titanium oxide mainly includes solvothermal method. This method has extremely high reaction temperature, strict requirements on equipment, high cost, and obtains titanium oxide powder through drying, so that nano-titanium oxide is in the drying process due to its high Hard agglomeration can occur on the surface to generate secondary particles, and the size is not nanoscale, so the small size effect will be lost

Abstract

The invention discloses a preparation method of an anti-ultraviolet finishing agent for silk fabric. The preparation method comprises the following steps: filling 25-50mL of propylene glycol into a conical flask, dropwise adding 5-10mL of tetrabutyl titanate into the conical flask, introducing nitrogen gas with water at 60-80 DEG C and stirring for 30-60min; removing moisture in the conical flask by using a rotary evaporator at 80-100 DEG C, adding 5-10g of sodium stearate and 2-5g of hydroxyethyl cellulose into the conical flask, and carrying out water-bath ultrasonic treatment for 1-2h to obtain mixed paste; transferring the mixed paste in the conical flask into a high-speed dispersion machine, adding a wetting agent, a softening agent, a defoaming agent, a dispersing agent and a coupling agent, and stirring for 60-90min at 10000-15000r / min to obtain the anti-ultraviolet finishing agent for silk fabric. The anti-ultraviolet finishing agent for silk fabric has good heat resistance, is not easy to decompose when being heated, is non-toxic, is harmless to human body, has good biodegradability and facilitates environmental protection.

Description

Technical field: [0001] The invention relates to the technical field of silk, in particular to a preparation method of an anti-ultraviolet finishing agent for silk fabrics. Background technique: [0002] Silk is a continuous long fiber that is solidified by secreting silk liquid when cooked silkworms make cocoons, also known as "natural silk". Like wool, it is one of the earliest animal fibers used by humans. According to different foods, it is divided into silkworms, tussah silkworms, cassava silkworms, camphor silkworms, willow silkworms, and celestial silkworms. Silk fabrics are widely loved by people because of their elegant appearance, comfortable wearing, and softness. However, with the improvement of people's living standards, people have higher and higher requirements for the functionalization of silk fabrics. Developed, such as antibacterial finishing, anti-acid finishing, anti-ultraviolet finishing and so on. [0003] In recent years, the ozone layer in the atmos...
