preparation example 1

[0057] Preparation of polystyrene modified nano silica:

[0058] Mix 1000g of nano-silica and 10kg of ethanol, add 300g of KH550 dropwise at 55°C for 1 hour, continue stirring for 3 hours, filter and dry in an oven at 55°C for 1 hour to obtain KH550 modified nano-silica ;

[0059] Mix 10g of azobisisobutyronitrile and 500g of ethanol to form a catalyst solution, mix 1000g of KH550 modified nano-silica, 1500g of styrene, 200g of polyvinylpyrrolidone, 100g of water and 9.5kg of ethanol, then add dropwise at 50°C After the catalyst solution was added dropwise for 1 hour, the stirring reaction was continued for 7 hours. After the reaction, it was filtered and dried in an oven at 55° C. for 1 hour to obtain polystyrene-modified nano-silica.

preparation example 2

[0061] Preparation of polystyrene modified nano silica:

[0062] Mix 1000g of nano-silica and 12kg of ethanol, add 450g of KH550 dropwise at 70°C for 1 hour, continue stirring for 1 hour, filter and dry in an oven at 55°C for 1 hour to obtain KH550 modified nano-silica ;

[0063] Mix 20g of azobisisobutyronitrile and 500g of ethanol to form a catalyst solution, mix 1000g of KH550 modified nano-silica, 2000g of styrene, 400g of polyvinylpyrrolidone, 300g of water and 11.5kg of ethanol, then add dropwise at 65°C After the catalyst solution was added dropwise for 1 hour, the stirring reaction was continued for 9 hours. After the reaction, it was filtered and dried in an oven at 55° C. for 1 hour to obtain polystyrene-modified nano-silica.

Abstract

The invention relates to the field of silica gel products, and particularly discloses a cleaning type silica gel wrist strap and a production process thereof. A cleaning type silica gel wrist strap comprises a wrist strap part and a liquid storage part connected to the wrist strap part. A liquid storage cavity is formed in the liquid storage part, a liquid taking opening communicated with the liquid storage cavity is formed in the outer wall of the liquid storage part, and the liquid storage part is connected with a closing block clamped and matched with the liquid taking opening. The wrist strap part and the liquid storage part are prepared from the following raw materials in parts by weight: 100 parts of hydroxyl polydimethylsiloxane; 20-40 parts of 1, 5-naphthalene diisocyanate; 8-15 parts of a plasticizer; 0.15-0.3 parts of a catalyst; and 10-18 parts of a filler. According to the cleaning type silica gel wrist strap, the function of the silica gel wrist strap is added, and the alcohol resistance of the wrist strap is high.

Description

technical field [0001] This application relates to the field of silicone products, more specifically, it relates to a clean silicone wristband and its production process. Background technique [0002] A wristband is an accessory tied to the wrist, which plays an important role in production and life, such as a sports wristband, which can be used as an ornament; there is also an identification wristband, where information such as a QR code is set on the wristband , and then wear the wristband on the corresponding person, the identity information of the person can be identified by scanning the QR code, especially suitable for emergency patients and the elderly. [0003] With the development of the silicone industry, silicone is not only used to make large industrial products, but also to make small decorations. Silicone wristbands are a common one, because silicone wristbands have good elasticity, light weight, good shock resistance and easy to carry. The advantages of silico...
