Description
Technical field
The present invention relates to a kind of coating levelling agent, more specifically to polyethers, alkane modified polyorganosiloxane and in coating as the purposes of flow agent.
Background technology
In order to overcome coating bad disadvantage of levelling in the coating decoration process, coating is flowed and drying and forming-film after obtain smooth filming, need be controlled film coated surface.
In order to improve the levelling property of coating, can adopt the surface tension that reduces between coating and the base material, make coating and ground have good wettability; Adjust evaporation rate of solvent; Reduce viscosity; Improve the flowability of coating; Prolong flow time; In film coated surface formation unimolecular layer as thin as a wafer, so that uniform surface tension to be provided.By the adding of anti-shrinkage cavity, flow agent, just can all or part ofly satisfy above condition, thereby obtain better levelling effect, make film coated surface smooth smooth.
The past adopts in solvent based coating often with ketone, ester class, aromatic hydrocarbons or the main multi-functional fine solvent of being made up of the high boiling solvent mixture for improving the paint flow levelling, thereby adjusted the evaporation rate of solvent, made coating in drying process, have average evaporation rate and solvency power.In Air drying coating, because of solvent evaporation is fast, dope viscosity is excessive, flows and hinder.At this moment, it is effective using the solvent based flow agent.Only increasing solids constituent that solvent can make coating descends and causes disadvantage such as sagging; Perhaps keep solvent, only add high boiling solvent and adjust evaporation rate and improve levelling, consequently prolong time of drying.
Another kind of coating levelling agent is to be main constituent with the restricted long-chain resin of consistency, as cellaburate class, polyacrylate(s) etc.Can reduce the surface tension between coating and the ground and improve wettability.But its molecular weight is lower, and is not exclusively miscible with the resin of coating.Can form defectives such as depression, shrinkage cavity, orange peel on the cured coating film surface like this.
The third coating levelling agent is to be main constituent with the restricted long-chain polysiloxane of consistency, as phenylbenzene polysiloxane, methyl phenyl silicone and organic radical modified polyorganosiloxane etc.It has the mobile effect of control surface, plays and improves the levelling effect.And after solvent evaporates, polysiloxane forms unimolecular layer in film coated surface, be one deck as thin as a wafer and slick film, thereby improve the gloss of filming.Polysiloxane itself is a kind of tensio-active agent, can improve the wettability to ground again, thereby reaches the purpose of improving levelling.
Organosilicon is prevented the action effect of shrinkage cavity, flow agent, depends on the chemical structure and the usage quantity of polysiloxane.As polysiloxane molecule amount size, the type of organic group and position, the Siliciumatom type of attachment all will influence its action effect.How having experimental results show that its consumption has side effects on the contrary.
Because polydimethylsiloxane is poor to the coating resin consistency, can increase its consistency by the modification of phenyl.But can only provide limited effect to coating, tangible levelling effect is promptly arranged, not have and add lustre to, increase sliding effect, in formulation for coating material, use not general.
Have been found that organic radical modification polymethyl siloxane is as containing the organopolysiloxane of multiple organic group modifications such as polyethers, alkane, reactive organic radical, as long as select suitable big or small organic radical, on long-chain polysiloxane part chain belt Si atom, adopt the Si-C key mode of hydrolysis to connect organic group simultaneously, this class modification organopolysiloxane compound has good wettability, improve levelling property effectively, promote gloss, slippery and anti scuffing performance.
