Problems solved by technology

[0006] The object of the present invention is to provide a kind of protective mask with control valve and preparation method thereof, comparatively loaded down with trivial details to solve the existing protective mask production mode with control valve that proposes in the above-mentioned background technology, operation is many, in control valve and In the combination of fabrics, there is room for improvement in strength and sealing. During long-term wearing, it is very easy to reduce the protective effect or fail due to loose accessories. At the same time, this type of mask is generally used in harsh environments. High temperature often occurs. Although the protective mask with a control valve can quickly discharge the water, it is not strong enough. During the long-term wearing process, it will still cause breathing difficulties, which will easily lead to insufficient oxygen supply to the brain and a feeling of fatigue. , which is a very dangerous problem at work

preparation example Construction

[0030] The invention provides a protective mask with a control valve and its preparation method, which can improve the combined strength and sealing performance, and increase the refreshing effect. Please refer to Figure 1-5 , including cloth 100, control valve 200, condensation sheet 300 and combined ring 400;

[0031] see again figure 1 , the front side wall of the cloth 100 is fixedly connected to the nose bridge strip 110, specifically, the nose bridge strip 110 is sewn on the front side wall of the cloth 100, and the left and right side walls of the cloth 100 are bonded with ear ropes 120;

[0032] see again image 3 , the rear side wall of the control valve 200 and the front side wall of the cloth 100 are fixedly installed, specifically, the front side wall of the cloth 100 is socketed with the control valve 200, and the rear side wall of the control valve 200 is provided with a combination hole 210, and the control valve 200 The front side wall is integrally formed w...

Embodiment 1

[0050] S1: Raw material preparation:

[0051] Selection of outer materials: select conventional spunbonded non-woven fabrics in the market;

[0052] Core material selection: select conventional melt blown cloth in the market;

[0053] Selection of inner materials: select conventional moisture-resistant and anti-stick non-woven fabrics in the market;

[0054] Spun-bonded non-woven fabrics, melt-blown fabrics, and moisture-resistant and anti-stick non-woven fabrics are classified and stored, and raw materials are protected from unpacking, and raw materials that have not been unpacked are not allowed to be sent directly to the cleaning work area;

[0055] S2: Pressing and lamination: After the production machine, the spunbond non-woven fabric, meltblown fabric and moisture-resistant anti-sticking non-woven fabric are laminated together, and pressure is applied. The pressure duration is 5S, and the spunbond non-woven fabric needs to be guaranteed. The cloth is the first layer, t...

Abstract

The invention discloses a protective mask with a control valve and a preparation method thereof, and belongs to the technical field of protective devices. The mask comprises cloth, the control valve,a condensation sheet and a combined ring; the front side wall of the cloth is connected with the control valve in a sleeving manner; the condensation sheet is clamped in the control valve. According to the protective mask with the control valve and the preparation method thereof, the steps are simplified on the basis of preparation of a conventional protective mask; in the combination process of the control valve, the valve is opened; the buckle combination and the gluing are matched; the strength and the sealing performance of the control valve are ensured; the protection grade and the service life of the protective mask are effectively ensured; a layered structure is additionally arranged in the control valve; the compression pieces and the separation nets are combined on the two sides of the condensation piece and arranged between the combination holes and the outer ring in a built-in mode, in the reciprocating breathing process, and water vapor is rapidly discharged, so the purposeof refreshing can be achieved in cooperation with the traditional Chinese medicine compression piece structure, the wearing comfort in the severe environment is improved, nerve relaxation caused by stuffiness is reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of protective devices, in particular to a protective mask with a control valve and a preparation method thereof. Background technique [0002] Medical protective equipment refers to protective equipment used to protect the personal safety and health of medical personnel and patients during medical care and treatment, including protective clothing, protective skirts, protective gloves, protective glass plates, protective caps, gonad protective equipment, protective glasses, etc. Other protective equipment. [0003] Masks are a category of medical protective equipment. Medical masks are mostly made of one or more layers of non-woven fabrics. The main production processes include melt blown, spunbond, hot air or acupuncture, etc., which have the ability to resist liquids and filter particles. Equivalent to bacteria, it is a kind of medical protective textile. [0004] Among them, the protective mask with a co...
