Embodiment Construction
[0029] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings.
[0030] An appropriate amount of the protein salting-out agent shown in Table 1 was slowly and uniformly added to a certain amount of concentrated natural latex with a solid content of 60% in batches under stirring conditions, and then placed in an ice bath for a certain period of time until the protein was precipitated. After complete centrifugation and filtration, the results are recorded in Table 1.
[0031] Get a certain amount of deproteinized natural latex as shown in Table 2 in the reaction vessel, then add the vulcanizing agent and vulcanization accelerator as shown in Table 2 to obtain a mixed solution, and ripen at room temperature for 1 to 2 days;
[0032] The foaming agent shown in Table 2 and the prepared antibacterial and antifungal agent solution were added to the above mixed solution for foaming. During the foaming process, first...

The invention discloses an anti-allergy, antibacterial and anti-mildew natural latex sponge material. The natural latex sponge material comprises deproteinization natural latex, an antibacterial and anti-mildew agent, a vulcanizing agent, a vulcanization accelerator, an anti-aging agent, a gelatinizing agent and a foaming agent. The anti-allergy, antibacterial and anti-mildew natural latex spongematerial disclosed by the invention is free of an allergy problem after being in contact with human bodies, and is applicable for being used by all kinds of people; moreover, the natural latex spongematerial also has relatively high antibacterial and anti-mildew effects, and is a nontoxic, safe and low-cost product; the preparation technology is simple and practicable, the equipment requirement is low, and industrial production is easily realized.
Description
technical field [0001] The invention relates to the technical field of natural latex preparation, in particular to a natural latex sponge material with anti-allergy, antibacterial and mildew resistance, a preparation method and application thereof. Background technique [0002] Natural latex sponge is one of the important types of latex products. It is a low-density porous rubber material prepared from latex through mechanical foaming, chemical foaming, blowing foaming and other processes. Natural latex sponge has the advantages of low relative density, light weight, excellent cushioning performance and elasticity, rapid recovery after deformation, creep resistance and permanent deformation resistance, fatigue resistance, aging resistance and other excellent characteristics, and has good insulation. Heat, sound insulation, cushioning and shock absorption properties, can be made into flame retardant, oil resistance, chemical resistance and other properties of products. The ...
