Embodiment 1

[0025] Embodiment 1: First, the water-based hydroxyacrylic emulsion resin emulsion is added to a dispersion tank according to 90% by mass for dispersion, and then water is added to dilute and stirred for 10 minutes. The aqueous hydroxyacrylic emulsion resin emulsion dispersion is polymerized by free radical solution. The negative ions in the water are mixed with the water-based hydroxyacrylic emulsion resin emulsion, diluted, and then 4% of the water-based wetting agent is added to the dispersion kettle, and then the free-radical solution polymerization is carried out with the water-based hydroxyacrylic emulsion resin emulsion, and the surface activity of the water-based wetting agent Agents are composed of hydrophilic groups and lipophilic groups, and then the hydrophilic groups and lipophilic groups are polymerized with free radicals in the water-based hydroxyacrylic emulsion resin emulsion, and then the liquid forms a continuous phase on the surface of the water-based hydroxy...

Embodiment 2

[0027]Embodiment 2: First, the water-based hydroxyacrylic emulsion resin emulsion is added to the dispersion tank according to the mass of 93% for dispersion, and then water is added to dilute, and stirred for 15 minutes, and the water-based hydroxyacrylic emulsion resin emulsion dispersion is polymerized by free radical solution. The negative ions in the water are mixed with the water-based hydroxyacrylic emulsion resin emulsion, diluted, and then 6% of the water-based wetting agent is added to the dispersion kettle, and then the free-radical solution polymerization is carried out with the water-based hydroxyacrylic emulsion resin emulsion, and the surface activity of the water-based wetting agent Agents are composed of hydrophilic groups and lipophilic groups, and then the hydrophilic groups and lipophilic groups are polymerized with free radicals in the water-based hydroxyacrylic emulsion resin emulsion, and then the liquid forms a continuous phase on the surface of the water...

Abstract

The invention relates to the technical field of water-based PU varnish, and discloses a water-based PU varnish process and device. The water-based PU varnish process comprises the steps: 1, adding 90-95% by mass of water-based hydroxyl acrylic emulsion resin emulsion into a dispersion kettle, dispersing, adding water, diluting, stirring for 10-15 min, and sequentially adding 4-8% (by concentrationpercentage) of a water-based wetting agent into the dispersion kettle; and 2, adding 0.2-0.45% (by mass percentage) of a water-based defoaming agent into the dispersion kettle, and further stirring for 20-30 minutes in the dispersion kettle. According to the water-based PU varnish process and device, 90% by mass of water-based hydroxyl acrylic emulsion resin emulsion is added into a dispersion kettle to be dispersed, then water is added for dilution, and then 4% by mass of a water-based wetting agent is added into the dispersion kettle, so that the water-based PU varnish is low in impurity content, stable in using effect, not prone to corrosion and high in wear resistance, and the varnish production process flow is reduced.

Description

technical field [0001] The invention relates to the technical field of water-based PU varnish, in particular to a water-based PU varnish process and device. Background technique [0002] Due to its good compressive strength and bending strength, as well as its natural, irreproducible, and unique texture effects, wood has become the material of choice for high-end residential wooden doors and windows both from a practical and aesthetic point of view. The energy consumption is small, and the heat preservation and heat insulation of the room after installation, especially the sound insulation performance, has significant advantages compared with other windows, and it is easy to maintain and replace. Various solid wood doors and windows also represent the trend of the times in which man and nature are integrated. Due to the special physical and mechanical properties of wood, chemical composition characteristics, and the location of the building structure where wooden doors and w...
