Embodiment 1

[0012] A latex sponge, comprising the following materials according to the weight ratio in the preparation process: hexadienoic acid: 100 parts, polyvinyl alcohol: 35-75 parts, nano silicon dioxide: 0.5-1.5 parts, polystyrene resin: 0.2-0.6 parts Parts, silicone oil: 1.2-1.3 parts, foaming agent is water: 1.5-3.5 parts; hexadienoic acid is grafted polyether, polyoxypropylene glycol, polyoxyethylene-propylene oxide synthesized from high-activity polyether-based polyether Composed of copolymerized trihydric alcohol and polyoxypropylene glyceryl ether; polystyrene resin is triethylenediamine; silicone oil is soft foam silicone oil.

[0013] The above raw materials obtain a latex sponge with a density of 40D according to the production method of the slow rebound sponge, which is soft to the touch. The physical properties are as follows: elongation: 175%, tensile strength: 51.7kPa, hardness: 7ILD.

Abstract

The invention discloses latex sponge which is composed of the following substances in parts by weight according to the preparation process: 100 parts of hexadienoic acid, 35-75 parts of polyvinyl alcohol, 0.5-1.5 parts of nanosilicon dioxide, 0.2-0.6 part of polystyrene resin, 1.2-1.3 parts of silicon oil and 1.5-3.5 parts of foaming agent water. Due to adjustment on product raw materials and formulae, the latex sponge which is free of rubber pungent smell is produced by using a slow springback sponge processing process, the latex sponge is sponge intrinsically, but has the properties of latex, in addition is prior to latex and has no pungent smell of latex; and the latex sponge is soft, smellless and good in comfort, double requirements of sponge and latex can be met simultaneously, and sponge and latex can be completely replaced. The foaming density of the latex sponge is about 40D, a great amount of raw materials are saved, and the density of finished product latex is at least 70D.

Description

technical field [0001] The invention relates to a latex sponge. Background technique [0002] With the improvement of people's living standards, people's requirements for sponge products are also getting higher and higher. When people choose sponges, they mainly judge by its touch and elasticity. Soft and elastic sponges are often popular with consumers. Latex sponge is a kind of sponge with cellular structure. Compared with ordinary sponge, it has high elasticity, good bearing capacity, comfortable and durable. At the same time, since latex cannot be vacuum-packed, its application and market space are limited. Contents of the invention [0003] The purpose of the present invention is to provide a latex sponge without rubber irritating smell, high density and vacuum packing. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a latex sponge, which is composed of the following materials according to the wei...
