An improved paint mixer is disclosed which includes a base and an upper cabinet pivotally connected to the base. The upper cabinet can be pivoted from a first rearward position which provides access to a front section of the base and a second forward position which provides access to a rear section of the base. As a result, both the front and rear section of the base are easily accessible for service, maintenance, and cleaning. A support system that includes three adjustable legs provides improved support and stability. Casters disclosed at the rear end of the bottom of the base along with a recessed wall of the base and a handle disposed at the front of the base make it easier to move and / or relocate the mixer. Non-stick coatings in the form of a paint-resistant coating or an anti-graffiti coating to the inside surfaces of the mixer facilitate the removal of accumulated paint.

The invention relates to a waterborne two-component adhesion and doodling prevention coating, which is prepared by mixing a component A and a component B according to the proportion of NCO / OH=1.5-2, wherein the component A is prepared from the following components in part by weight: 60 to 80 parts of waterborne polyurethane, 0.3 to 0.6 part of dispersing agent, 0.4 to 0.8 part of defoaming agent, 0.1 to 0.5 part of wetting agent, 1 to 5 parts of modified hydroxyl polydimethylsiloxane resin, 3 to 7 parts of waterborne wax emulsion, 0.6 to 1 part of polyurethane thickening and flatting agent and 5 to 35 parts of water; the modified hydroxyl polydimethylsiloxane resin comprises 22.5+ / -0.5 percent of NCO in percentage by weight; and the component B is hydrophilic aliphatic polyisocyanate of hexamethylene diisocyanate. The coating has equivalent permanence doodling prevention performance with an oily polyurethane doodling prevention coating and an oily fluorocarbon doodling prevention coating, and also has the characteristics of wear resistance, washing resistance, weather fastness and environmental protection.

The invention relates to a water-based anti-doodling paint which is a double-component paint composed of a component A and a component B. The component A comprises the following components in percentage by weight: 15-35 wt% of water-based hydroxy polyacrylate dispersion, 15-35 wt% of organosiloxane-modified water-based hydroxy polyacrylic resin, 5-15 wt% of ultraviolet-resistant filler, 0.1-0.6 wt% of defoaming agent, 0.5-1.5 wt% of leveling agent, 0.5-2 wt% of anti-aging agent, 0.5-1 wt% of wetting and dispersing agent and the balance of water, totaling 100 wt%. The component B comprises the following components in percentage by weight: 60-80 wt% of hydrophilic modified aliphatic polyisocyanate curing agent and the balance of solvent, totaling 100 wt%. The ultraviolet-resistant filler is selected from nano rutile titanium white. The water-based anti-doodling paint provided by the invention has the advantages of favorable water resistance, excellent aging resistance, high medium and pollution resistance and obvious self-cleaning action.

The invention discloses an anti-fouling and anti-doodling dope and a preparation method. The dope contains the following ingredients(based on weight portions): 15-20 portions of biradical fluoro-acrylate oligomer, 3-10 portions of biradical silicone acrylate oligomer, 10-40 portions of 6-radical polyurethane acrylate oligomer, 1-30 portions of biradical epoxy acrylate oligomer, 1-10 portions ofphotoinitiator, 10-25 portions of reactive diluted monomer, 0.5-5 portions of addition agent and 10-25 portions of organic solvent. Paint film made from the anti-fouling and anti-doodling dope is structurally compact, with surface tension reaching 27-33dyne / centimeter and effectively prevents various doodling materials, such as oil pen, waterborne pen, ink jet and pollutant from infiltrating to thedope or the substrate, thus reducing cleaning difficulties; meanwhile, the dope is good in dirt resistance and doodling resistance and long in service life. The dope can be prepared by mixing the ing redients of the dope to be even, so the preparation method is economic and simple.

The invention relates to preparation of fluorine-containing organosilicone modified anti-graffiti paint, in particular to preparation of organosilicone polyester modified cyclopropyl resin. The resin,namely cationic resin, can be used in both aqueous paint and electrophoretic paint, plays an anti-graffiti self-cleaning role in the electrophoretic paint, and is prepared from a fluorine-silicon modified emulsion and high-performance color paste in a ratio of 6:1. The preparation has the advantages that paint products have high storage stability; the paint has high salt spray resistance, high weather resistance and high functionality after electrophoretic coating, and is applicable to painting of kitchens and places with high self-cleaning requirements; the paint is water-based two-componentanti-graffiti electrophoretic paint, and is convenient to apply, environmentally friendly and safe to use; the surfaces of boards are smooth and bright, the functionality is high, and the stability of tank liquor is also high; coatings have high mechanical property, acid-alkali resistance, weather resistance and salt-pray resistance.

The invention relates to an industrial coating, in particular to an anti-doodling coating for an outdoor facility and a preparation method of the anti-doodling coating. The anti-doodling coating mainly aims at solving the technical problems that a doodling coating in the prior art contains a bonding agent, has higher attaching power on a general surface, and is relatively difficult to remove by using a physical or chemical method after setting in case of vicious doodling, and the surface is prone to being damaged.
