Abstract
The invention relates to the technical field of woodware coatings, in particular to an aqueous wood-wool filling agent coated onto a woodware, and a preparation method thereof. The aqueous wood-wool filling agent coated onto the woodware comprises distilled water, propylene glycol, a wetting dispersant reagent, a defoaming agent, a pH value regulating agent, powdery matter, aqueous polyurethane dispersoid (PUD) resin, antiseptic bacteriacide and droxyethylcellulose. The aqueous wood-wool filling agent coated onto the woodware is prepared through adding the materials at different time at different stirring speed. The aqueous wood-wool filling agent coated onto the woodware not only can be directly used without being diluted by a solvent, has short drying time and can be directly coated with primer without polish, but also can be manually operated and is environmentally friendly, and especially, the adhesion of the primer can be enhanced after the aqueous wood-wool filling agent coated onto the woodware is wiped and dried.
Description
Technical field
The present invention relates to the woodwork coating technical field, particularly relate to water-based wood wool weighting agent of a kind of woodwork coating and preparation method thereof.
Background technology
The wood wool weighting agent is to play a part to fill timber conduit, filling wood grain hair on the neck eye conduit in the coating process of woodenware, not only can reduce priming paint spraying number of times, and easy to use, and can need toning according to the client, reaches simultaneously and fills and painted purpose.Its operational method: with the even wiping of the reverse wood grain of cotton cloth waste, or the scraper blade coating; Operation thing as larger area needs operation rapid (being difficult for wiping after drying) to be used further to along the grain wiped clean of cloth.
Present existing wood wool weighting agent is mainly common oiliness wood wool weighting agent, and it is not only relatively poor to adhering to of coating, and contains more organic solvent, not only not environmental protection, and exist and wait that the time of doing is longer, need the shortcomings such as polishing.
Summary of the invention
In order to address the above problem, one of purpose of the present invention is to provide a kind of and waits that the time of doing is short, the water-based wood wool weighting agent of the woodwork coating of priming on can not polishing directly.
Two of purpose of the present invention has been to provide the preparation method of the water-based wood wool weighting agent of described woodwork coating.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of water-based wood wool weighting agent of woodwork coating comprises the following material that counts by weight percentage:
The summation of above substance weight per-cent is 100%;
Wherein, wetting dispersing agent is the water-based dispersion moisture agent, and defoamer is the water-based defoamer, and water-based PUD resin is the water-based aliphaic polyurethane resin, and anticorrosion and bactericidal agent is general water-borne coatings sterilant.
Wherein, preferred 2-amino-2 methyl isophthalic acids of described pH value adjusting agent-propyl alcohol.
Described opaque is that purity is 99% silicon dioxide powder.
The 8916A of the preferred Changxing chemistry company limited of described water-based PUD resin (ETERNAL).
The ACTICIDE RS of preferred Thor Chemie GmbH of described anticorrosion and bactericidal agent (THOR).
The mixture that the WET270 of the preferred German Di Gao company limited of described wetting dispersing agent (TEGO) and water mix according to 1:1.
The emulsification polysiloxane defoamer of the preferred sea of described defoamer this special chemical company (ELEMENTIS) of name.
Prepare the method for the water-based wood wool weighting agent of described woodwork coating, comprise being prepared as follows step:
Steps A, distilled water and the propylene glycol of described amount are put in reactor, stirred under 80～120 rev/mins 3～8 minutes;
Step B, drop into again wetting dispersing agent, the defoamer of described amount in the reactor, and stirring velocity in reactor is brought up to 500～800 rev/mins; After first with pH value adjusting agent, the pH value of the mixture in reactor being transferred to 8.5～9.0, then add opaque in the stirring of 500～800 rev/mins of rotating speeds, add opaque after stirring velocity rise to 800～1200 rev/mins, stirred 25～35 minutes
Step C, add water-based PUD resin, anticorrosion and bactericidal agent in reactor, change that in reactor, stirring velocity is 700～900 rev/mins, stirred 10～20 minutes;
Step D, add Natvosol at last in reactor, change that in reactor, stirring velocity is 800～1200 rev/mins, stirred 15～25 minutes, make the water-based wood wool weighting agent of described woodwork coating.
The present invention includes distilled water, propylene glycol, wetting dispersing agent, defoamer, pH value adjusting agent, opaque, water-based PUD resin, anticorrosion and bactericidal agent, Natvosol; Add by different time, stir under different stirring velocitys and get, one aspect of the present invention use environmental protection raw material (such as waterborne polyurethane resin PUD, propylene glycol etc.) comes the part place of water with propylene glycol, simultaneously to improve the shortcoming of water.Use Natvosol on the one hand, its used water is melted out fully, plays thickening, result of prevention, and the energy film forming has larger help to the operability of improving weighting agent.Wherein, UV coating also belongs to environmental protection coating material, can affect its sticking power if timber contains grease, and water-based wood wool weighting agent has the effect of oil sealing fat, can increase sticking power.Use after the present invention can on be coated with water-borne coatings, solvent based coating or UV coating.In a word, it is short that the water-based wood wool weighting agent of woodwork coating of the present invention not only waits to do the time, primes on need not polishing directly, also can the directly use without solvent cut; And manually actuated, environmental friendliness especially can be promoted adhering to of priming paint after the wiping examination after doing.
