Problems solved by technology

However, the mold mattress has higher requirements on appearance and performance, and the cost is higher
In the mold mattress production industry, due to the high temperature in summer, the cooling of the mold is slow, and the high temperature of the mold will cause surface shrinkage and die dissatisfaction.
Therefore, in order to improve the yield rate, manufacturers use more cold water or reduce production speed to reduce mold temperature, but this causes waste of resources and energy, and increases costs.

Abstract

The invention discloses a production process of a mold mattress. The invention relates to the field of latex industry, in particular to a production process for high-temperature production of mold mattresses. The invention provides a mold mattress production process, which is convenient to process, improves the product stability and reduces the cost. According to the invention, the phenomena of surface shrinkage, insufficient die punching and the like can be reduced during high-temperature production, a curing agent can be smoothly hydrolyzed in foamed latex due to high die temperature and guarantee of certain latex temperature, the gelling effect is ensured, and the phenomena of layering or poor structural tension and the like caused by poor gelling effect are avoided. According to the invention, the yield is improved, and the production efficiency is also improved.

Description

technical field [0001] The invention relates to the field of latex industry, in particular to a production process for high-temperature production of mold mattresses. Background technique [0002] The latex bedding industry is generally divided into mold mattresses and sheet mattresses. Because mold mattresses are produced by molds, the heat conduction effect of the molds is high, and latex has good gelation and vulcanization effects in the molds. The product is light in weight, uniform in structure and delicate, The performance is better. However, mold mattresses have higher requirements on appearance and performance, and the cost is higher. In the mold mattress production industry, due to the high temperature in summer, the cooling of the mold is slow, and the high temperature of the mold will cause surface shrinkage and die dissatisfaction. Therefore, in order to improve the yield rate, manufacturers use more cold water or reduce production speed to reduce mold temperat...
