Description
Technical field
The present invention relates to a kind of preparation method of polymer-wax, particularly a kind of water-borne wax emulsion increasing leather polishing degree.
Background technology
Oxidized polyethylene wax emulsion is applied to the fields such as water color ink, water lustering oil, agricultural, leather, shoe polish, forestry, wooden industry, gardens industry, water-borne coatings, water-miscible paint, paper product tamanori, yarn fabric softening agent and water-fast arrangement.Have that particle diameter is tiny, good waterproof performance, hardness of film are high, tack-free, be the excellent additive of coating, leather, weaving, ink.It can also be used for ink, lustering agent, polishing wax, liquid shoe cream, liquid automobile polish, liquid floor wax and liquid leather jacket wet goods field.
CN102030996 relates to a kind of water-soluble OP wax emulsion and preparation method thereof, this OP wax emulsion is made up of to calculate with wt% the OP wax of certainweight number, fatty alcohol-polyoxyethylene ether, aliphatic alcohol polyoxyvinethene phosphate salt, deionized water and comprises following component OP wax 19.5-32 part, fatty alcohol-polyoxyethylene ether 2.54-9.25 part, aliphatic alcohol polyoxyvinethene phosphate salt 0.45-1.58 part, deionized water 65-70 part, select agent-in-oil method technique by reactor heating and melting, add stirring successively.
CN101503517 relates to a kind of preparation method of cationic-nonionic modified oxidated polyethylene wax emulsion, first low-molecular-weight oxidized polyethlene wax organic bases is carried out esterification modification, then use sun-nonionic compound emulsifier to carry out emulsification, then carry out compositely obtaining cationic-nonionic modified oxidated polyethylene wax emulsion.This product can be applied to the fields such as process hides covering with paint, fruit freshness preserving.Be characterized in that the emulsion institute of modified waxes is electrically charged for positively charged ion, the wax emulsion-stabilizing of the more single cationic emulsifier emulsification of shelf characteric.
Existing known technology mostly adopts fatty alcohol-polyoxyethylene ether series of surfactants as primary emulsion, and wherein oleophilic group is connected with ehter bond with hydrophilic group part, and stability is not high, also has influence on the stability that emulsion uses.
