Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of high-quality stearic acid utilizing glyceryl tristearate to prepare
Zinc.
Background technology
Zinc stearate belongs to the one of stearate apoplexy due to endogenous wind, be mainly used as nontoxic polyvinyl chloride stabilizer, the lubricant of cosmetics,
Styrene resin, the releasing agent of hard rubber article, paint flatting agent and rubber industry do the softening agent of sizing material, interleaving agent, should
With quite varied.Along with industrial expansions such as plastics, coating and petrochemical industries, domestic market is to the demand of zinc stearate year by year
Increase.
At present, the commonly used double decomposition of domestic production zinc stearate synthesizes, and its concrete technology is with stearic acid as primary raw material,
With water as medium, carry out saponification by adding sodium hydroxide after stearic acid heating and melting, add zinc salt the most in the reaction product
Aqueous solution carries out metathesis reaction and generates metallic soap precipitation, finally removes by-product with substantial amounts of washing, then through water dumping, the work such as is dried
Skill, obtains zinc stearate finished product.Double decomposition reaction condition is gentle, and the color and luster prepared is good, stability is high, but exists and produce
Efficiency is low, energy consumption and the shortcoming such as water consumption is high.And double decomposition produce discharge during zinc stearate substantial amounts of chloride, sulfate radical from
The waste water of son, causes the biggest pollution to environment；Simultaneously as product metal soap is to generate in surfactant sodium soap solution
, therefore granule is little, dispersion is high, surface adsorption is strong for precipitation, thus causes filter cake moisture content high, and energy consumption for drying is big, product
Apparent density is big, and dust from flying is serious, packaging agent accumulating expense is high.Fusion method is that industrial wide variety of another is hard

2%-6%, its preparation technology is to be dividedly in some parts zinc oxide and catalyst after stearic acid melts, and has reacted rear fused mass through double rod pressures
Sheet machine cooling compression molding i.e. obtains described super-thin sheet-shaped zinc stearate.It is with short production cycle that fusion method prepares zinc stearate, arranges without waste liquid
Putting, product does not contains other inorganic salt anion, few with water, but the product prepared to there is purity low, free fatty acid content
Height, the problems such as product color is bad.
It is high the most in various degree to there is production cost in the zinc stearate that most domestic zinc stearate manufacturer is produced, production process
Environmental pollution is serious or the zinc stearate for preparing by People's Republic of China's chemical industry standard, " HG/T3667-2012 is stearic
Acid zinc " problem such as detection part index number is the most up to standard, and particularly free acid content is high, its preparation technology and quality still need to change further
Entering, thus limit the application in its at home and abroad market, high-quality zinc stearate mostly relies on import, expensive.
Therefore, study a kind of overall manufacturing low cost, production process safety and environmental protection, zinc stearate that product quality is high have higher warp
Ji benefit and social benefit.
