Sponge and production method for sponge

Abstract

The invention discloses a sponge and a production method for the sponge. The production method comprises the following steps that firstly, an isolation layer is arranged on the surface of a sponge main body; secondly, a gel layer is attached to the isolation layer; thirdly, a protection layer is arranged on the surface of the gel layer to form the sponge with an ice-cold touch feeling. According to the production method disclosed by the invention, the isolation layer is compounded on the surface of the sponge firstly and the gel layer is compounded secondly, and the isolation layer is capable of effectively preventing the gel layer from permeating in the sponge; the sponge with the structure ensures the ice-clod touch feeling during using, and further ensures the low cost during production, namely, ensures the usage amount of the gel layer.

Description

technical field [0001] The invention relates to a sponge with ice-cold touch and a preparation method thereof. Background technique [0002] Sponge is widely used to make cushions such as chair cushions, seat cushions and mattresses, as well as pillows because of its great deformation ability. In a hot environment, for the use of wood, rattan and other furniture, people usually no longer use sponge pads, but use them directly. Although this method has a cool feeling, it cannot meet the needs of softness and comfort, so there are If you buy a water pad with a cool touch, the water pad will have a certain soft touch, but the comfort level cannot be compared with the sponge. [0003] Therefore the inventor just invents the sponge with ice-cold touch, as figure 1 , 2 As shown, it is mainly composed of a layer of gel layer 2' on the surface of the sponge main body 1'. The gel is a substance with a cool touch and a certain fluidity, and it uses the porosity of the sponge to eff...

Problems solved by technology

[0004] However, due to the porosity of the sponge, the gel has weak fluidity. Over time, the gel on the surface of the sponge will penetrate into the sponge, making the gel layer thinner and thinner, which will inevitably reduce the cold touch of the sponge surface.
