Problems solved by technology

However, when in use, the water vapor produced by human breathing will cause fog inside the mask, which will affect the conversation effect and use experience
[0003] With the continuous development of mask air filter materials, existing masks are usually made of multi-layer non-woven fabrics and ordinary fabrics. In order to increase the filtering effect of air filter materials, it is often necessary to increase the thickness of the filter material, but the increase in thickness makes The user feels difficulty in breathing and the comfort level decreases

Abstract

The invention discloses a water-permeable dustproof protective film. The protective film is prepared from the following raw materials in parts by weight: 20-30 parts of polyvinyl chloride, 8-16 partsof polyvinyl trimethylsilane, 2-6 parts of polyvinyl pyrrolidone, 1-5 parts of dicumyl peroxide, 50-100 parts of solvent and 3-15 parts of additives. The water-permeable dustproof protective film disclosed by the invention can meet the requirements of filter layer materials of masks on specific function protecting actions and be used for prolonging service lives of the masks and enhancing a use effect of the masks, and thus, the experience effect of users is improved. The invention discloses a preparation method for the water-permeable dustproof protective film.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a water-permeable and dust-proof protective film and a preparation method thereof. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose, made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. However, when in use, the water vapor produced by human breathing will cause fog inside the mask, which will affect the conversation effect and use experience. [0003] With the continuous development of mask air filter materials, existing masks are usually made of multi-layer non-woven fabrics and or...
