Embodiment approach

[0032] According to a specific embodiment provided by the present invention, the weight percentage of the resin is: 0.01-8%, the weight percentage of the inorganic mineral powder is: 0.01-8%, and the weight percentage of the normal temperature volatile solvent is: 0-8%. 35%, the weight percentage of the moisture-absorbing inorganic salt is: 0-5%, and the balance is water.

[0033] According to a specific embodiment provided by the present invention, the weight percentage of the resin is: 0.1-5%, the weight percentage of the inorganic mineral powder is: 0.1-5%, and the weight percentage of the normal temperature volatile solvent is: 0.1-5%. 30%, the weight percentage of the moisture-absorbing inorganic salt is: 0.01-3%, and the balance is water.

[0034]According to a specific embodiment provided by the present invention, the resin is one or more of water-soluble phenolic resins, amino resins, alkyd resins, epoxy resins, and acrylic resins. The water-soluble phenolic resin, am...

specific Embodiment approach

[0036] According to a specific embodiment provided by the present invention, the moisture-absorbing inorganic salt is one or more of calcium chloride, magnesium chloride, and magnesium sulfate. Calcium chloride is a colorless cubic crystal, white or off-white, granular, honeycomb block, spherical, irregular granular, powder. It is highly hygroscopic and easily deliquesces when exposed to the air. Magnesium chloride is a colorless, bitter, water-soluble crystal with strong hygroscopicity. Magnesium sulfate is a commonly used chemical reagent and drying reagent. It is a colorless or white crystal or powder, odorless, bitter in taste, and deliquescent.

[0037] According to a specific embodiment provided by the invention, the inner packaging base material layer 3 is a non-woven fabric or a paper base material, and the non-woven fabric and paper base material are easy to be colored, and can be colored in different colors or designed according to different situations. Patterns, n...

Embodiment 1

[0048] The present embodiment provides the preparation method of described discoloration coating 4, comprises the following steps:

[0049] Step 1: Weighing the weight percentage and weighing the material, the weight of each component of the material is respectively: acrylic resin: 35g, calcium silicate: 50g, diethylene glycol butyl ether: 180g, water: 735g;

[0050] Step 2: Add water into the three-roll mill, start grinding, and the speed is 60rpm;

[0051] Step 3: Under stirring state, add weighed acrylic resin: 35g, calcium silicate: 50g, diethylene glycol butyl ether: 180g in order; grind all the above materials for 30min after adding;

[0052] Step 4: Stop stirring, separate the mixture from the grinder and store it in a sealed container;

[0053] Step 5: Apply the above-mentioned mixed material to the inner packaging substrate layer 3 made of non-woven fabric by 50-mesh screen printing;

[0054] Step 6: Air shower until the water evaporates, then seal and store.

Abstract

The embodiment of the invention discloses a color-changing display warming paste and a preparation method of a color-changing coating, and belongs to the technical field of personal care, the color-changing display warming paste comprises a covering layer, a heating layer, an inner packaging base material layer and the color-changing coating, the covering layer, the heating layer, the inner packaging base material layer and the color-changing coating are sequentially arranged from inside to outside, the upper layer of the inner packaging base material layer is colored, and the color-changing coating is printed on the coloring surface of the inner packaging base material layer; the color-changing coating contains resin, inorganic mineral powder, a normal-temperature volatile solvent, inorganic salt easy to absorb moisture and water. Under the condition of normal temperature, light rays can penetrate through the color-changing coating and reach the inner packaging base material layer, so that the inner packaging base material coloring layer is presented through the color-changing coating; in the using process, the normal-temperature volatile solvent is gradually volatilized, the color of the inner packaging base material coloring layer cannot penetrate through the color-changing coating, and the appearance of the product only shows the color of the color-changing coating. The heating temperature can be early warned so that a consumer can timely find the overheating condition in the using process.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of personal care, in particular to a method for preparing a color-changing display warm sticker and a color-changing coating. Background technique [0002] At present, the heating temperature, steam effect, and heating performance of warming patch products on the market, such as warm baby, steam eye mask, moxibustion patch, shoulder and neck patch, etc., are the product performances that consumers focus on. However, in the actual use process, consumers cannot intuitively observe the actual effects of these aspects, and only rely on their own physical sensations to feel the effects of the warm patches used, resulting in a single, boring or even indifferent product experience. For diabetes or some elderly people who have poor temperature sensitivity, they cannot sense temperature changes in time during use, which may even cause adverse use consequences such as low-temperature burns, w...
