Abstract

The present invention continues scentetd indoor paint, coating itself belongs to the watersoluble polyvinyl alcohol coating series, handle through acetalation, eliminate the defective of poor water resistance, contained components such as water glass in the paint binder, had good abrasion resistance, perfuming material in the coating and cyclodextrine form microcapsule structure, and covered by filmogen, make fragrance remaining time lasting, low emit fragrance.But perfuming material of the present invention also other multiple indoor building coating of adapted has same aroma retaining effect.

Description

Continue scentetd interior architecture coating

The present invention is a kind of building and ornament materials for continuing scentetd indoor building material.

Except that comprising excellent water tolerance, scrub resistance, not shedding, weather resistance and good brushing performance, also should possess good decoration functions and the effect of beautifying the environment to the requirement of indoor paint.At present existing numerous coating has partly satisfied above-mentioned requirements, as polyvinyl alcohol type coating, comprise polyvinyl alcohol water glass coating, have good filming, polyvinyl formal coating particularly, its performance index are improved, and all are significantly increased as water tolerance, scrub resistance, but further improve the indoor paint performance, particularly give coating new beautify life function, improve the living environment quality, produce more comfortable effect, be still people's demand certainly.

Task of the present invention is to give interior architecture coating to continue scentetd function, and living environment is beautified more, and is comfortable pleasant.

The main component of its base-material of coating of the present invention is a polyvinyl alcohol, in order to overcome its hydrophilic interaction, make it in the presence of catalyzer, carry out the hydroformylation condensation and form acetal compound, and finish condensation between part differing molecular key and form undissolved three-dimensional Polymer Structure, eliminated the defective of poor water resistance.Perfuming material of the present invention is to utilize the film-forming properties of water-soluble poval and the cavity and the essence of cycloheptaamylose molecule to play emulsifying effect; the essence molecule enters the cycloheptaamylose cavity and forms microcapsule structure; or protected by filmogen; reduce the volatility of essence molecule greatly, reach the effect that continues slowly to put perfume.

Strong and the washability of the present invention's coating major advantage water tolerance, not shedding, persistence are good, nontoxic, odorless, strong covering power, the exquisiteness of filming, good decorating effect, particularly continue to distribute the fragrance of pleasing the people, make amenity, glad.

Be one embodiment of the present of invention below: with polyvinyl alcohol (CH ₂CH ₂OH) the n(polymerization degree=1700) 6 parts, 80 parts of mixed dissolutions of water keep 80 ℃ of temperature to add 30% technical hydrochloric acid and stir for 3 parts, add formaldehyde and carry out acetalation for 4 parts, add 1 part in 30% sodium hydroxide then, regulate PH=7-8, when 40 ℃ of left and right sides of temperature, add water glass Na ₂SiO ₃6 parts, stir the tributyl phosphate (CH that the back adds the about 0.1-0.2% of base-material weight ₃CH ₂CH ₂CH ₂O) ₃PO ₄Till lather collapse, regulate PH=8.4-8.7 with hydrochloric acid again, promptly obtain base-material.Will be by 65 parts in lime carbonate, 15 parts in zinc sulfide white, stir in the filler adding base-material of 20 parts of compositions of talcum powder, put the perfuming material that accounts for coating weight 0.15% into, add the polyvinyl alcohol water solution that is used as sizing material then, base-material, sizing material, filler three's ratio is about 61: 14: 25, and then adds a small amount of fluorescent bleaches and a spot of tributyl phosphate stirs, add an amount of colorant through ball milling, filter and promptly obtain above-mentioned coating.

The preparation of perfuming material is by 3 parts of polyvinyl alcohol, is dissolved in 45 parts of 90-100 ℃ of hot water, adds 2 parts of cycloheptaamyloses, and high-speed stirring adds 50 parts of essence and promptly obtains the cycloheptaamylose inclusion compound, carry out behind the filtration drying.But perfuming material of the present invention also adapted uses in the building coating of other kind and obtains same aroma retaining effect.
