Abstract

The invention relates to the field of latex, and aims at the problem that the preparation process of latex sponge is not environmentally friendly, and provides a production method of an environment-friendly latex sponge. Zinc oxide and potassium hydroxide are mixed, aged in a water bath, shaped with hot air, vulcanized in a steam box, and dried to obtain a latex sponge. The vulcanization package dispersion is composed of sulfur and an accelerator. Agent ZBOP / S. The present invention uses an environmentally friendly vulcanization accelerator with little environmental pollution, little irritating odor and no harm to the skin, uses natural latex and / or synthetic latex as main raw materials, and adopts methods such as mechanical blending and vulcanization to produce latex sponges, and the product performance meets the requirements. , the production process also achieves the purpose of green environmental protection.

Description

technical field [0001] The invention relates to the field of latex, in particular to a production method of an environment-friendly latex sponge. Background technique [0002] Latex sponge is a low-density porous open material, which can also be said to be a rubbery continuous foam. Latex sponges are widely used in mattresses, pillows, sofas, insoles and other fields because of their many characteristics, such as excellent cushioning and decompression performance, compression fatigue resistance, good thermal insulation and heat resistance, etc. The latex is made into a latex sponge after a series of steps such as pre-vulcanization, foaming, shaping, steam vulcanization, and drying. The rubber accelerator plays an important role in the steam vulcanization and drying section. The so-called accelerator is a substance added to the rubber compound that can shorten the vulcanization time and reduce the vulcanization temperature. The addition of accelerator can activate the vulca...
