Disclosed is a latex sponge. The latex sponge is prepared by using the following substances in parts by weight in a preparation process: 100 parts of polyether polyol, 35 to 75 parts of isocyanate, 0.5 to 1.5 parts of ethylene glycol, 0.2 to 0.6 part of catalyst, 1.2 to 1.3 parts of silicone oil, and 1.5 to 3.5 parts of foaming agent water. By adjusting raw materials and a formula of the product, the latex sponge without pungent smell of rubber is produced by using a slow-resilience sponge treatment technology, the latex sponge is essentially sponge but has characteristics of latex, and the latex sponge is better than latex and has no pungent smell of latex; and the latex sponge is soft, odorless and strong in comfort, can meet requirements of people on both sponge and latex, and ca completely substitute the sponge and latex. A foaming density of the latex sponge of the present invention may be approximately 40D, a large quantity of raw materials is saved, and a density of the finished latex is at least 70D. |
