Water-based coating application crosslinking agent
Water-based coatings, including water-based wood lacquer, are coatings of water for dispersing medium and diluents. The formulation system is a more complex system than the commonly used solvent coatings.
Formula design, not only to focus on the type of polymer, the performance of the emulsion and dispersion. Also need to choose all kinds of additives and considering the interactions between various components and reasonable matching. Sometimes special additives are selected for special requirements, and the formulation is finally formulated.
By means of nuclear shell emulsion polymerization technique, the film is synthesized by the synthetic emulsion, and by adding zinc oxide as the crosslinking agent, the stable crosslinking emulsion is made.
By the experiment, the additive method of the monomer acrylic can be added to the shell layer, and its addition is 7% ~ 9%. The temperature of the zinc oxide added in 55 ~ 65 ℃ advisable; The addition of zinc oxide is n (ZnO) : n (-coo -) value is 0.5 ~ 0.6; Of self crosslinking emulsion mixture wood coatings, the room temperature dry coating are fast drying, high hardness, easy to burnish, good adhesion resistance characteristic, satisfy the application in the primer, as well as some cane implement technology products on the coating requirements. The drawback is that the water resistance can meet the general requirements, but it needs to be improved.
The basic composition of the recipe
1) water-based resin: this is the base material of the film, which determines the main function of the paint film.
Film agent: after the water evaporates, the emulsion or dispersal particles form a uniform dense membrane and improve the film properties under low temperature conditions.
3) antifoaming agent and antifoaming agent: inhibits the bubbles created in the paint in the production process and can cause the bubbles to escape and break the bubbles.
4) leveling agent: improving the performance of paint, forming a smooth, smooth coating.
Wetting agent: improving the wettability of the paint liquid to the bottom, improving the level of flow and increasing the adhesion of the coating to the substrate.
6) dispersant: promoting the dispersion of the pigment in the paint solution.
Rheological agent: it provides good liquidity and fluidity to the paint, reducing the malady in the coating process.
Thickening agent: increases the viscosity of the paint fluid, improves the coating's wet film thickness, and has the anti-precipitation and anti-stratification effect on putty and solid color paint.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Antiseptic: prevents the paint from mouldy during storage.
10) fragrance: make the paint liquid have a pleasant smell
11) colorants: mainly for color paint, which is the desired color for water-based paint. Colorants, including pigments and dyes, are used in solid paint (not to show wood grain coating), and dye for transparent paint (to show the coating of wood grain).
Packing: mainly used for putty and solid color paint, adding solid and reducing cost.
PH: adjust the pH of the paint liquid to keep the paint liquid stable.
14) wax emulsion or wax powder: improve the resistance of paint film and improve its feel.
15) special additives: aimed at the special requirements of water-based paint to add fertilizer, such as rust inhibitor (tin can packaging to prevent premature rusting), a hard agent (increase film hardness, flatting agent (decrease) of paint film burnish, scratch resistance, increased slip agent (improve film shooting) and anti aging agent (to prevent coating overlying adhesion), crosslinking agent (made from bi-component paint, improve the comprehensive performance), hate water (the coating with lotus leaves effect), wear-resisting agent (increase the wear resistance of coating), uv absorber (outdoor paint anti-aging, prevent yellow), etc.
16) ionized water: a small amount of deionized water is often added for the formulation of the formula.
