Abstract

The invention relates to a high-elastic adhesive for coir mattress. The adhesive comprises the following ingredients (by weight): 200-300 parts of natural latex, 100-50 parts of sericin, 10-25 parts of magnesium methacrylate, 20-30 parts of 20% sodium stearate aqueous solution, 20-30 parts of dicumyl peroxide, 1-2 parts of a vulcanization accelerator, 2-3 parts of an anti-aging agent, 1-2 parts of a mildew inhibitor, 0.5-1 part of a flexibilizer and 80-100 parts of a dispersant. By the addition of magnesium methacrylate, vulcanization rate of natural latex can be accelerated, and degree of vulcanization is raised. Under the action of dicumyl peroxide, magnesium methacrylate can remarkably improve mechanical properties and thermal aging resistance of natural latex.

Description

technical field [0001] The invention belongs to the field of mattresses, and relates to coconut palm mattresses, in particular to an adhesive for high-elastic coconut palm mattresses and a preparation method thereof. Background technique [0002] The processing method of the coconut palm mattress is as follows: the natural coconut palm rope is processed by unbending, laying, glue spraying, drying, hot pressing, vulcanization and setting to form a cushion core, and then processed into a coconut palm mattress with various fabrics. . In order to effectively prolong the service life of the mattress, the adhesive used in the glue spraying process is required to have good toughness, elasticity and strength. However, the adhesives used by companies producing coconut palm mattresses are generally low in strength and poor in toughness, and it is difficult to vulcanize and shape the mattress after hot pressing, and it is easy to make the mattress go out of the line and collapse. Adh...
