Problems solved by technology

[0003] Although corresponding measures have been taken in the production to mix the materials as evenly as possible and control the vulcanization time, it is still impossible to overcome the product defects caused by the immature or overripe latex before foaming
The most typical is that some small bubbles in the foamed rubber material will combine with each other to form large bubbles and the foam will rupture, resulting in many small pits on the surface of the latex mattress, which not only affects the appearance of the latex mattress, but also seriously affects the product. quality, resulting in waste of resources

Abstract

The invention provides an intermittent vulcanized latex sponge mattress production technology which is capable of improving bearing performance and comfort by vulcanizing and ripening latex and auxiliaries before foaming. The intermittent vulcanized latex sponge mattress production technology includes the steps of 1), grinding and refining raw materials; 2), using a compounding system for automatically compounding according to a formula, wherein the raw materials comprise, by weight, 80-100 parts of natural rubber, 0-20 parts of rubber polymer, 3-10 parts of vulcanizing agent, 1-8 parts of activator, 0.5-6 parts of emulsifying agent, 1-5 parts of accelerant and 0.5-5 parts of gels; 3), mixing and prevulcanization; 4), adding a hardening agent, foaming by a foaming machine, conducting injection molding and surface setting; 5), using a vulcanizing device for vulcanizing, washing with water after vulcanizing, cooling, drying and punching; 6), cutting and winding so as to obtain a sponge mattress. The sponge mattress produced according to the technology has the advantages of high elasticity, shock absorption, good bearing performance and excellent comfort and durability.

Description

technical field [0001] The invention relates to the technical field of production of natural latex sponge mattresses, in particular to a production process for intermittently vulcanized natural latex sponge mattresses. Background technique [0002] In production and processing, the production of latex sponge by Dunlop method is to transport all the raw materials into a mixing tank according to the formula. After stirring evenly, the mixed latex is directly foamed and flowed into the injection mold (laid on the conveyor belt) through the pipeline. Set in hot air at 80-90°C for 10-15 minutes, then vulcanize with hot air or hot steam, then wash with water, cool, punch, and cut to shape. [0003] Although corresponding measures have been taken in the production to mix the materials as evenly as possible and control the vulcanization time, it is still impossible to overcome the product defects caused by the immature or overripe latex before foaming. The most typical is that some...
