Problems solved by technology

However, if the filter parts of silicone rubber masks and silicone masks do not achieve multi-layer filtration at the same time, filter cotton is used, such as synthetic fiber filter cotton, non-woven fabric filter cotton, glass fiber filter cotton, activated carbon filter cotton, etc., use one at most A kind of filter cotton, with one or more layers of filter cotton for air filtration, trying to prevent the new coronavirus from invading the human body, but the actual effect is very different. At present, the production method of most silicone masks is mainly composed of filter materials, filter channels, exhaust valves, The silicone face sealing cover and the face sealing cover are all made of silicone material to prevent harmful gas from leaking into the mask

Embodiment 1

[0017] (1) In parts by weight, 40 parts of fumed white carbon black, dihydroxy polydimethylsiloxane, 8 parts of vinyl tributylketoxime silane, 25 parts of N-(β-aminoethyl) - 8 parts of γ-aminopropyltrimethoxysilane, 90 parts of raw methyl vinyl silicone rubber, kneading in a high-speed mixer at 60°C for 1 hour to form a base material; (2) 90 parts of the prepared base material, 4 parts of dimethyl azobisisobutyrate and 0.6 part of dicumyl peroxide were mixed on a double-roll machine at 120°C, and then 23 parts of supported catalyst white carbon black and 0.05 part of 1-ethynyl cyclohexanol were added. The rubber raw material was masticated in an internal mixer for 2 minutes, and then added 25 parts of eucommia gum, 5 parts of zinc oxide, 1.0 part of stearic acid, 1.5 parts of anti-aging agent, 1.0 part of accelerator, 2.0 parts of three Allyl isocyanurate is mixed for 2 minutes and then heated for 120 seconds. When the mixing temperature reaches 160°C, the glue is discharged, ...

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to a preparation method of a shaped antibacterial face sealing cover material for a protective mask, which is simple in production process and wide in raw material source, is prepared by blending gutta-percha and organic silicon and adopting a white carbon black supported catalyst with high efficiency, is lightand comfortable, can breathe through the nose, is wide in visual field and can avoid oral air leakage. The material has good biocompatibility and low sensitivity, reduces the risk of allergic reactionin use, has good hygiene, is difficult for bacteria and fungi to grow and propagate, has strong durability and plasticity, has soft and skin-friendly comfort, and has hardness close to that of humanskin.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a preparation method of a shaped antibacterial face sealing cover material for a protective mask. Background technique [0002] Silicone masks have been developed for anti-virus and anti-fog in the early years, and the choice of silicone masks has a relatively long service life and is soft and comfortable. Wearing for a long time, it is not easy to cause allergic reactions. However, silicone materials are also divided into different degrees of hardness and softness. Masks with high hardness can easily cause facial indentations, while masks with low hardness may not be worn securely and are prone to air leakage. According to our understanding, the silicone masks and silicone mask products called anti-smog on the market are actually only made of silicone material for the part attached to the face. The main part is still made of plastic, and the air is filtered through a ...
