Abstract

The invention relates to the field of leather manufacturing, and in particular relates to a formaldehyde removal agent for removing residual formaldehyde of fur and a preparation method of the formaldehyde removal agent. Raw materials of the formaldehyde removal agent comprise the following components in parts by weight: 10-100 parts of main material, 10-40 parts of retanning filling agent, 1-5 parts of absorbent, 1-20 parts of surfactant, 1-20 parts of PH value regulator and 10-50 parts of reducing agent, wherein the main material is one or a mixture of more of amino compounds or ester compounds. The formaldehyde removal agent provided by the invention is prepared by blending the amino compounds or the ester compounds which are used as the main material and the reducing agent and some adding auxiliary agents for improving the formaldehyde removal performance which are used as an auxiliary material so as to ensure that the amino compounds or the ester compounds perform chemical reaction with formaldehyde, thus a formaldehyde removal effect is achieved. The formaldehyde removal agent is good in formaldehyde removal effect, and can ensure that a leather also has the original performances without causing damages to the leather while removing formaldehyde.

Description

technical field [0001] The invention relates to the field of leather manufacturing, in particular to an aldehyde remover for removing residual formaldehyde from fur and a preparation method. Background technique [0002] In the fur industry, formaldehyde tanning agent is currently an irreplaceable organic tanning agent, but it can enhance the softness of fur, improve fullness, reduce the difference in parts and many other advantages, which cannot conceal the fact that it produces free formaldehyde. Free formaldehyde can damage people's eyes, throat, chest cavity, etc. Long-term inhalation can damage some tissues of the human body, weaken the immune system of the human body, and cause certain harm to human health. Therefore how to remove free formaldehyde and can keep the self cortex quality of fur is a problem demanding prompt solution. Contents of the invention [0003] The object of the present invention is to provide a kind of aldehyde removal agent and its preparation...
