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 a latex sponge. The latex sponge comprises the following raw materials in parts by weight: 100 parts of hexadienoic acid, 35-75 parts of polyvinyl alcohol, 0.5-1.5 part of nanometer silicon dioxide, 0.2-0.6 part of a polystyrene resin, 1.2-1.3 part of a silicon oil, 1.5-3.5 parts of water as a foaming agent. The latex sponge without rubber irritation smell is produced by the processing technology of slow rebound sponge through adjusting the raw materials and formula of the product, the sponge is essentially a sponge, but it has the characteristics of latex, and is superior to latex, and has no irritation smell of latex; the latex sponge is soft, odorless and comfortable, which can meet the parallel demand of people for sponge and latex, and can completely replace sponge and latex. As that foam density of the latex sponge of the invention can be about 40D, a large amount of raw materials are saved, and the density of the finished 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...
