Problems solved by technology

However, paraffin wax lacks toughness, is brittle and brittle, and its adhesion performance is not ideal at the same time, so the depilatory agent with paraffin wax as the main component must be supplemented with a tackifier (such as poly (iso) butene, cis (trans) polybutylene, etc. ethylene, ethylene vinyl acetate copolymer, etc.), toughening agent (polyethylene wax, polypropylene wax, polystyrene, etc.), also need to add dispersant (such as fatty acid metal salt, quaternary ammonium salt, span, etc.), through physical The method is to modify the paraffin to improve the adhesion characteristics of the paraffin

Abstract

A method for preparing a depilatory agent relates to the technical field of livestock and poultry slaughtering and processing. Under nitrogen protection, a paraffin mixture and maleic anhydride are subjected to a graft reaction in the presence of an initiator to obtain modified paraffin; By blending, the depilatory agent for livestock and poultry slaughtering and processing is obtained. The invention does not contain rosin and its derivatives, has good thermal stability and safety, and is a novel, safe and efficient depilatory for livestock and poultry slaughtering and processing.

Description

technical field [0001] The invention relates to the technical field of slaughtering and processing of livestock and poultry, in particular to a preparation method of a depilatory agent used for depilation during processing. Background technique [0002] Hair removal is an important link in the slaughtering and processing of livestock and poultry, and it is generally completed by machinery. However, after mechanical processing, ducks and geese still have a large amount of fine fluff, and some parts of pigs (such as pig heads and trotters) are difficult to achieve the effect of complete hair removal, so it is necessary to increase the "secondary hair removal" process. Artificial secondary hair removal is time-consuming and cumbersome, with high labor costs and low production efficiency. Most processing companies only rely on depilatory agents. Rosin was once a commonly used depilatory, but it is potentially harmful to human health. In 2009, my country promulgated the "Food S...
