Cold-hot dual-purpose pad and manufacturing method thereof

Abstract

The invention discloses a cold-hot dual-purpose pad and a manufacturing method thereof. The manufacturing method is characterized by comprising the following steps of: superimposing two layers of heat-sealing calendaring films together, then performing high-frequency welding on the three edges by using a strip aluminium mold to manufacture an outer bag, then filling the prepared sol into the bag, removing the air in the bag, sealing, and flattening the sol in the bag till the sol is completely cured and set. The sol is prepared from water-soluble low-molecular-weight polymer, a cross-linking agent, a cross-linking agent modifier, a surface active agent, a preservative, a humectant and pure water according to certain proportion and steps. The cold-hot dual-purpose pad disclosed by the invention is good in softness and enough in elasticity, has a fixed shape, can be used in summer and winter and overcome the defect that the traditional pad only can be used for the summer, and is generally suitable for being used as a cushion, a mattress, a pet pad and a vehicular back cushion.

Description

technical field [0001] The invention relates to a mat, in particular to a dual-purpose mat for cold and heat and a manufacturing method thereof. Background technique [0002] At present, the mats used on the market are mainly bamboo mats, straw mats and water mats. These mats can play a certain role in preventing heatstroke and cooling in summer, like bamboo mats. Poor performance, heat cannot be transmitted, the temperature rises quickly, and the coolness lasts for a relatively short time. In addition, the bamboo board is hard, and people will feel uncomfortable when sleeping on it. After a long time of use, the bamboo board is easily broken or damaged. Cracks, punctures the human skin, causes certain harm to people, and has a short service life; the straw mat is relatively soft, smooth, and feels comfortable, but it is easy to absorb moisture. And long mites; the water cushion is very soft and can maintain the cooling effect for a long time, but it takes a long time to fi...

[0002] At present, the mats used on the market are mainly bamboo mats, straw mats and water mats. These mats can play a certain role in preventing heatstroke and cooling in summer, like bamboo mats. Poor performance, heat cannot be transmitted, the temperature rises quickly, and the coolness lasts for a relatively short time. In addition, the bamboo board is hard, and people will feel uncomfortable when sleeping on it. After a long time of use, the bamboo board is easily broken or damaged. Cracks, punctures the human skin, causes certain harm to people, and has a short service life; the straw mat is relatively soft, smooth, and feels comfortable, but it is easy to absorb moisture. And long mites; the water cushion is very soft and can maintain the cooling effect for a long time, but it takes a long time to fill or drain water, and it is not easy to move after filling the water, the fluidity of the water is also very large, the state is not fixed, and people sleep on it. It is relatively large, easy to wake up, easy to break when encountering sharp and hard substances, and needs to be constantly charged to maintain the water temperature, consumes too much energy, and has certain safety hazards
