A latex sponge is disclosed by the present invention, which is composed of the following substances in parts by weight in a preparation process: 100 pts. wt. of polyether polyol, 35-75 pts. wt. of isocyanate, 0.5-1.5 pts. wt. of glycol, 0.2-0.6 pts. wt. of catalyst, 1.2-1.3 pts. wt. of silicon oil, 1.5-3.5 pts. wt. of foaming agent and water. By adjusting the raw material and recipe of the product, a latex sponge without pungent smell of rubber can be produced by adopting the manufacturing process of the slow rebound sponge. The essence of the latex sponge is sponge, but it has the characters of latex and has no pungent smell as latex, which is better than latex. The latex sponge is soft and comfortable, has no smell, satisfying the paralleling requirements of sponge and latex, and can replace the sponge and latex completely. The foaming density of the latex sponge of the present invention can be around 40D and the density of the end latex sponge is at least 70D, so that lots of raw materials are saved,. |
