Technical Field

The invention relates to the technical field of environment-friendly anti-yellowing agents, and particularly relates to an environment-friendly anti-yellowing agent.

Background

The open-cell foam is a porous material composed of high-molecular substance and gas, and its solid-phase and gas-phase complex are different from those of closed-cell multi-block material, in which the former high-molecular substance and gas-phase are continuous, and the latter only has high-molecular substance and gas are separated. Due to the capillary action of the open-cell foam, it has excellent sustained absorption and penetration properties. In addition, the material has the advantages of light weight, high mechanical strength, mass production by using a forming die, and obtaining products with any shapes. The existing mattress sponge mostly adopts open-cell foam materials, but the open-cell foam materials used for manufacturing the mattress sponge have insufficient rebound effect and hand feeling.

Disclosure of Invention

The invention aims to solve the defects of resilience and insufficient hand feeling of a sponge open-cell foam material of a mattress in the prior art, and provides an environment-friendly anti-yellowing agent.

In order to achieve the purpose, the invention adopts the following technical scheme:

an environment-friendly anti-yellowing agent is designed, and comprises the following components: no phenolic phosphite, ultraviolet light absorber and light stabilizer;

preferably, the phenol-free phosphite ester, the ultraviolet light absorber and the light stabilizer are phenol-free phosphite ester: ultraviolet absorber: light stabilizer = 5: 3: 2.

a preparation process of an environment-friendly anti-yellowing agent comprises the following steps:

s1, preparing raw materials, namely weighing 40-50 parts of phenol-free phosphite ester, 30-40 parts of ultraviolet absorbent and 20-30 parts of light stabilizer in parts by weight, and putting the components into an oven for low-temperature drying and water removal;

s2, mixing the raw materials, adding the dried phenol phosphite ester, the ultraviolet absorbent and the light stabilizer into a stirring tank, and stirring and mixing;

s3, grinding the raw materials, namely adding the mixed particles of the phenol phosphite, the ultraviolet absorbent and the light stabilizer into a ball mill for ball milling, wherein the ball milling time is 2-5h, and the ball milling speed is 200-;

and S4, packaging and storing, and packaging and warehousing the ground mixed particles.

The environment-friendly anti-yellowing agent provided by the invention has the beneficial effects that: the prepared environment-friendly anti-yellowing agent has a good anti-yellowing effect, and does not need to be added with phenolic substances, so that the anti-yellowing agent has a five-toxin environment-friendly function when being applied to production of underwear sponges and shoe material sponges.
