Silica-gel-containing sponge mattress

Abstract

The invention discloses a silica-gel-containing sponge mattress which comprises 75-90 parts of polyurethane, 15-20 parts of silica gel, 0.2-0.3 part of silicon oil, 0.1-0.2 part of crosslinking agent, 0.2-0.3 part of foaming agent, 0.1-0.15 part of catalyst, 0.05-0.2 part of foam stabilizer and 1.5-2.5 parts of water. The invention also discloses a preparation method of the silica-gel-containing sponge mattress, which comprises the following steps: weighing the raw material components, grinding the silica gel into granules with the granularity of lower than 100 meshes, evenly mixing all the components, putting into a foaming machine, foaming, cooling, and making the mattress according to the conventional method. By adding the silica gel into the raw materials and combining the advantages of the sponge and silica gel, the prepared sponge mattress feels warm in winter and cool in summer, has the effect of keeping the temperature constant, and is not too cold in cold winter or too hot in hot summer. According to the manufacturing method, the silica gel is ground into the granules with the granularity of lower than 100 meshes, and all the raw materials are mixed, foamed, cooled and prepared into the mattress according to the conventional mattress production method. The method is simple in operation sequence and suitable for large-scale production.

Description

technical field [0001] The invention relates to household products, in particular to a sponge mattress containing silica gel. Background technique [0002] In daily life, people spend about half of their time sleeping, and mattresses are one of the important beddings. At present, most mattresses used by domestic people are composed of covering layers and spring layers. The disadvantages are: on the one hand The spring in the traditional mattress has a certain noise during the compression process; on the other hand, the spring in the mattress is easy to lose elasticity after a long time of use, which is easy to cause the mattress to form dimples locally, and the traditional mattress is breathable. Poor, the mattress has a short service life, which brings inconvenience to life. In addition, in the prior art, the mattress only meets the basic sleep requirements and lacks the health care function for the human body. Especially in hot summer, ordinary mattresses have slow heat ...

[0002] In daily life, people spend about half of their time in sleep. Mattress is one of the important bedding. At present, most of the mattresses used by domestic people are composed of covering layer and spring layer. The disadvantages are: on the one hand The spring in the traditional mattress has a certain noise during the compression process; on the other hand, the spring in the mattress tends to lose its elasticity after a long period of use, and it is easy to cause dimples in the mattress, and the traditional mattress is breathable Poor, the mattress has a short service life, which brings inconvenience to life

Polyurethane not only has the elasticity of rubber, but also has the strength of plastic and excellent processing performance. It can be used to prepare polyurethane slow-rebound foam. This kind of polyurethane slow-rebound foam is also called memory foam, which can be used in the manufacture of mattresses, but the current The sponge mattress has a single function, and does not have the comfort function and health care function
