The paste molecular sieve activation powder is a kneading material prepared by mixing 48-52% by mass of synthetic molecular sieve activation powder, 30-52% by mass of castor oil, and 0-20% by mass of a viscosity adjusting agent, wherein the synthetic molecular sieve activation powder is subjected to high temperature calcination dehydration. The paste molecular sieve activation powder of the present invention is applicable for raw material dehydration in fields of polyurethane coatings, paints and the like, wherein product performances are maintained, phenomena of blistering, attachment to the wall, and poor mobility can be prevented, and bad dispersion of the coating during a use process causes the phenomena.
Description
Technical field
The present invention relates to a kind of molecular sieve preparation field technology, particularly a kind of paste molecular sieve activation powder.
Background technology
Reactive dual-component coating is present one type of more common coating, is divided into curing agent component and host component usually.The kind of this type coating is a lot, and range of application is also very wide, has favorable mechanical performance, higher solids content, is one type of rising coating variety at present.Modal reactive dual-component coating is a bicomponent polyurethane coating; Generally be made up of isocyanate prepolymer and hydroxy-containing resin two parts, main application direction has woodwork coating, car repair coating, anticorrosive paint, terrace lacquer, electronic paint, sapecial coating, polyurethane water-proof paint etc.
A lot of reactive dual-component coatings can react with the micro-moisture in system or the environment, finally cause in cured film, forming bubble, pin hole, also possibly reduce coating gloss.Therefore the moisture of removing in the reactive dual-component coating system is most important to its application.In the reactive dual-component coating there be the moisture source of trace: the micro-moisture that contains in the raw material, the water of pigment and filling surface absorption trace, the adsorbed water of coating in storage process, the moisture in construction environment.For eliminating the influence of micro-moisture, generally need in reactive dual-component coating, add deicer and remove moisture construction quality.The physics deicer is mainly molecular sieve, can remove the micro-moisture in the coating through in reactive dual-component coating, adding an amount of molecular sieve activation powder, guarantees construction quality, and molecular sieve activation powder can also play the strengthening action to coating simultaneously.
Be that mealy molecular sieve activation powder is directly added in the coating in early days, disperse inhomogeneously that complicated operation and part activation powder powder can fly away in air, cause wastage of material and very high dust pollution is arranged, working environment is more abominable; For head it off, my company proposes to make it to be in flow regime-paste through organic grease fixed member sieve activation powder, replaces mealy molecular sieve activation powder with paste molecular sieve activation powder, adding technology simply, be uniformly dispersed and do not influence working environment.
Organic dispersion medium must be avoided following problem with mixing of molecular sieve activation powder:
Molecular sieve activation powder is handled through high temperature dehydration; Water content is below 1.5%, and the moisture that in the preparation process, must control environment is when exposing in the air because of the activation powder; Micro-moisture is adsorbed by molecular sieve activation powder fast in the air; In 20min, adsorption moisture reaches more than 5%, has damaged the absorbent drying ability of molecular sieve.The preparation process adopts inert gas shielding among the present invention, stops the activation powder and directly contacts with air.
Molecular sieve activation powder mixes with organic dispersion medium for a long time; Moisture in the organic dispersion medium can be by molecular sieve adsorption; Cause adsorption capacity to descend, so organic dispersion medium must pass through deep dehydration, dehydration back organic media water content is reduced to below 0.001%.Can not influence the water separation capability of molecular sieve like this to polyurethane coating.
Effective mixing the between molecular sieve and the organic grease, must avoid organic grease to stop up molecular sieve pore passage, cause the part hole to stop up, do not have the effect of adsorption moisture.
Molecular sieve is a solid constituent, and bulk density is 0.7 g/ml more, and the low silica-alumina ratio molecular sieve is the high-hydrophilic material; And organic grease is hydrophobic grease, and lamination can appear in both mixing, through adding hydrophilic and oleophilic character in the viscosity modifier adjustment system; Through selecting effective viscosity modifier, and the ratio that adds solves the lamination problem that mixes, and makes molecular sieve abundant with mixing of organic dispersing agent; Bubble do not occur and pin hole is not reunited, place layering does not take place.
The paste molecular sieve activation powder of the present invention's preparation, the Static Water adsorbance has solved operating process to the ruined difficult problem of molecular sieve activation powder adsorption capacity more than 12% when 50% organic dispersing agent addition; Lotion after evenly disperseing is not stratified, wall built-up not; Solved bubble and wall cling phenomenon when the molecular sieve powder is applied to fluid-coating with paint, added organic dispersing agent molecular sieve activation powder afterwards, because the protective effect of organic dispersing agent; Make molecular sieve activation powder; Short time exposes in the air, can not absorb water fast and goes bad, and has reduced the operation easier that is applied in coating and the grease.
