Problems solved by technology

[0003] The patent document whose application number is 201210333688.6 provides a sponge and its production method. The prepared sponge consists of a sponge body, an isolation layer arranged on the surface of the sponge body, a gel layer attached to the isolation layer, and a gel layer located on the gel layer. The protective layer on the surface of the layer consists of a PU layer, a PE layer, a PP layer or a glue coating, and the protective layer is a film layer, a polyurethane coating, a PVE layer, an EVA layer, a TPU layer or a cloth layer. Although this kind of sponge has a certain cold touch when used, because the isolation layer, gel layer and protective layer are arranged on the surface of the sponge main body, each layer does not include a porous structure, so the air permeability of the sponge becomes poor. , after a long time of use, the sponge will still feel stuffy and hot, which will affect the use effect of the sponge

Embodiment 1

[0028] 1. A kind of coating adhesive is prepared, wherein the phase-change microcapsule emulsion accounts for 50% and the water-based polyurethane resin accounts for 50% by weight. Add 0.5% thickener and 0.15% green water-based color paste as color toning, run a high-speed dispersing mixer at 1000r / min for 10min, mix evenly, and make a coating glue;

[0029] 2. Use a roller coater to evenly coat the above-mentioned coating glue on the surface of the latex pillow at a constant speed. The specific process is as follows: figure 1 ;

[0030] 3. Quickly place the coated latex pillow in a blast oven at 90°C for about 20 minutes;

[0031] 4. Take out the coated latex pillow from the oven to obtain a cool and breathable latex pillow.

Embodiment 2

[0033] 1. A kind of coating adhesive is prepared, wherein the phase-change microcapsule emulsion accounts for 50% and the water-based polyurethane resin accounts for 50% by weight. Then add 1% thickener and 0.2% green water-based color paste as color toning, run a high-speed dispersing mixer at 800r / min for 10min, mix evenly, and make a coating glue;

[0034] 2. Add 3% foaming agent and 3% foam stabilizer by weight to the above coating glue, and foam 3 times;

[0035] 3. After the coating glue foam is stable and uniform, use a roller coater to evenly coat the foamed coating glue on the surface of the latex pad at a constant speed. The specific process is as follows: figure 1 ;

[0036] 4. Quickly place the coated latex pad in a blast oven at 110°C to dry for about 10 minutes;

[0037] 5. Take out the coated latex pad from the oven to obtain a cool and breathable latex pad.

Embodiment 3

[0039] 1. A kind of coating adhesive is prepared, wherein the phase-change microcapsule emulsion accounts for 75% and the water-based polyurethane resin accounts for 25% by weight. Then add 0.5% thickener and 0.15% green water-based color paste as color toning, run a high-speed dispersing mixer at 2000r / min for 10 minutes, mix evenly, and make a coating glue;

[0040] 2. Add 0.5% foaming agent and 3% foam stabilizer by weight to the above coating glue, and foam twice;

[0041] 3. After the coating glue foam is stable and uniform, use a roller coater to evenly coat the foamed coating glue on the surface of the latex pad at a constant speed. The specific process is as follows: figure 1 ;

[0042] 4. Quickly place the coated latex pad in a blast oven at 120°C to dry for about 5 minutes;

[0043] 5. Take out the coated latex pad from the oven to obtain a cool and breathable latex pad.

[0044]The finished product prepared by above-mentioned embodiment 1-3 has been carried out a...

Abstract

The invention provides a cool breathable latex product and a preparation method thereof. According to the cool breathable latex product and the preparation method thereof provided by the invention, coating glue containing phase-change microcapsules coats a surface layer of the latex product and a pore structure below the surface layer by adopting a roller coating mode, and substances such as paraffin in the phase-change microcapsules absorb heat to keep a temperature constant, so a cool feeling during contact is brought to a human body. According to the coating technology, a compact film cannot be formed on the surface of latex, so inconvenience caused by heat dissipation and sweat evaporation of the compact film formed by an existing gel technology is avoided; and the technology does not damage an original latex structure, does not block pores in the surface layer of the latex, retains the breathable characteristic of the latex, and enables a user to feel cool and air-breathable.

Description

technical field [0001] The invention belongs to the field of daily necessities, in particular to a cooling breathable latex product and a preparation process thereof. Background technique [0002] Latex pillow was developed for the first time in 1929. It is mainly produced by Dunlop technology and Traleigh. Because of their respective honeycomb air hole technology, latex pillow is more breathable than other pillows. Its main mechanism is that the honeycomb structure can effectively and quickly dissipate the heat generated by the human body. The gel pillow does not have the honeycomb pore structure of the latex pillow. It is composed of a polyurethane base and a gel material surface. It is more suitable for summer, but it will also generate heat for a long time. A kind of gel pillow is described in CN205548192U, utilizes surface layer gel to be able to give head, neck and body cold feeling. Because the surface layer of the pillow is covered by a whole piece of gel, there is...
