Embodiment 1

[0044] like figure 1 and figure 2 As shown, a color-changing functional mask includes a mask body 1 and ear straps 2 arranged on both sides of the mask body 1, and the mask body 1 is sequentially provided with an outer non-woven fabric layer 3 and a middle meltblown cloth layer 4 from the outside to the inside. And the inner non-woven fabric layer 5, the outer non-woven fabric layer 3 is the outer non-woven fabric layer made of the non-woven fabric dried after padding or spraying with the photochromic sunscreen mixed finishing liquid; the middle melt-blown fabric layer 4 For the gram weight of 20-60g / m 2 The inner non-woven fabric layer 5 is spunlace non-woven fabric or spun-bonded non-woven fabric or hot air non-woven fabric.

[0045] The upper part of the mask body 1 is provided with a nose bridge strip 6 .

[0046] The photochromic sunscreen mixed finishing solution is a finishing solution with photochromic and sunscreen functions prepared by mixing adhesive, antioxidan...

Embodiment 2

[0052] A preparation method of the color-changing functional mask described in the above-mentioned embodiment 1, the method comprises the following steps:

[0053] Step 1: Prepare a photochromic sunscreen mixed finishing solution: mix the adhesive, antioxidant, photochromic microcapsules and titanium dioxide anti-ultraviolet agent with water, adjust the mass concentration of the adhesive to 0.05-2%, antioxidant The mass concentration of the photochromic microcapsules is 0.05-1%, the mass concentration range of the photochromic microcapsules is 10-40%, and the mass concentration of the titanium dioxide anti-ultraviolet agent is 0.2-5%, that is, the photochromic sunscreen mixed finishing solution is prepared;

[0054] Step 2: Roll the non-woven fabric used for preparing the outer non-woven fabric layer 3 of the mask through a rolling groove equipped with a photochromic sunscreen mixed finishing solution, and roll out the excess photochromic sunscreen mixed finishing solution thro...

Embodiment 3

[0068] like figure 1 and image 3 As shown, a color-changing functional mask includes a mask body 1 and ear straps 2 arranged on both sides of the mask body 1, and the mask body 1 is sequentially provided with an outer non-woven fabric layer 3 and a middle meltblown cloth layer 4 from the outside to the inside. And the inner non-woven fabric layer 5, the outer surface of the outer non-woven fabric layer 3 is provided with a thermochromic printing layer 3-1; the middle melt-blown fabric layer 4 has a gram weight of 20-60 g / m 2 The inner non-woven fabric layer 5 is spunlace non-woven fabric or spun-bonded non-woven fabric or hot air non-woven fabric.

[0069] The thermochromic printing layer 3-1 is made by coating the thermochromic printing color paste on the outer surface of the outer non-woven fabric layer 3 to form a design pattern, and then drying it.

[0070] The preparation method of thermochromic printing paste is: mixing thermochromic microcapsules with surfactant, def...

Abstract

A color-changing functional mask comprises a mask body and ear belts arranged on the two sides of the mask body, and the mask body is sequentially provided with an outer non-woven fabric layer, a middle melt-blown fabric layer and an inner non-woven fabric layer from outside to inside. The outer non-woven fabric layer is made of a non-woven fabric which is padded or sprayed by a light-sensitive color-changing sunscreen mixed finishing liquid and then dried, or is made of a non-woven fabric which is printed into a design pattern by a temperature-sensitive color-changing printing paste and then dried; the middle melt-blown cloth layer is melt-blown cloth with the gram weight of 20-60 g / m < 2 >, and the inner non-woven fabric layer is spunlace non-woven fabric or spunbond non-woven fabric or hot air non-woven fabric. According to the color-changing functional mask and the preparation method thereof, the problem that a mask is single in function can be solved, the mask has the light-sensitive sunscreen / temperature-sensing color-changing function while providing the protection effect, the filtering efficiency of the melt-blown filtering layer is not affected, and the bacterium filtering efficiency and the particle filtering efficiency of the mask are not affected; the personalized effect is achieved, and meanwhile the safety protection effect of the mask is guaranteed.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a color-changing functional mask and a preparation method thereof. Background technique [0002] Affected by the new crown epidemic, masks have become a daily necessity, and the public has gradually formed the habit of wearing masks when going out. During the epidemic, masks are used as protective equipment, and bacterial filtration efficiency is the primary demand. In the post-epidemic era, the functionalization and differentiation of masks have become the focus of consumers. . [0003] The current mask function is relatively simple, only has the protective function, the color and pattern of the mask is single, and cannot realize the personalized functions such as light color change, sun protection, temperature change color, etc. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a color-changing functional mask and a pre...
