Embodiment 1

[0041] Prepare 100kg of the present invention's anti-formaldehyde net odor full-effect environmental protection water-based wood varnish, consisting of the following components:

[0042]

[0043] First, add core-shell pure acrylic emulsion and polyurethane modified acrylic emulsion into the dispersion tank and carry out medium-speed dispersion. The speed of the medium-speed decomposition is 600-800r / min, and then evenly mix in micron activated bamboo charcoal powder for high-speed dispersion After 15-30 minutes, wherein the high-speed dispersion speed is 1000-1500r / min, add net aldehyde emulsion and anti-scratch wax additives, water, dispersant, matting agent, defoamer, anti-settling agent and other components point. After dispersing at a medium speed for 40 minutes, take a sample to test the fineness and viscosity of the finished product. If the fineness of the finished product reaches 35-50 μm, the viscosity is 30-60 mm 2 / s is a qualified product, and then filtere...

Abstract

The invention discloses formaldehyde-resistance odor-removing total-effect environmental-friendly waterborne wood varnish and a preparation technology thereof. The wood varnish comprises the following components in percentage: 30 to 40 percent of formaldehyde removing emulsion, 15 to 25 percent of core-shell pure acrylic acid emulsion and polyurethane modified acrylic acid emulsion, 3 to 5 percent of bamboo carbon powder, 1 to 3 percent of scratch resistance wax additive, 0.2 to 0.5 percent of delustering powder, 0.1 to 0.2 percent of antifoaming agent, 0.5 to 1.5 percent of dispersing agent,0.1 to 0.3 percent of anti-sedimentation agent and 20 to 40 percent of water and auxiliaries. The preparation technology comprises the following steps of: firstly adding the core-shell pure acrylic acid emulsion and polyurethane modified acrylic acid emulsion into a dispersing cylinder and dispersing at an intermediate speed; then uniformly adding micron active bamboo carbon powder; after dispersing for 15 to 30 minutes at a high speed, adding the formaldehyde removing emulsion, the scratch resistance wax additive, the water, the dispersing agent, the delustering powder, the antifoaming agent, the anti-sedimentation agent and other components; after dispersing for 40 minutes at an intermediate speed, sampling and detecting the fineness and the viscosity of a finished product; and carryingout filtering, canning and packaging on the finished product.

Description

technical field [0001] The invention relates to a water-based wood varnish; in particular, the invention relates to a formaldehyde-resistant, deodorizing, full-effect, environmentally friendly water-based wood varnish, and also relates to a preparation technology for the formaldehyde-resistant, odor-free, full-effect, environmentally friendly water-based wood varnish. Background technique [0002] The existing domestic mainstream wood coatings mainly include the following types, polyurethane wood coatings (PU), acid curing amino alkyd wood coatings (Acidcuring), nitro wood coatings (NC), UV curing wood coatings (UV), water-based coatings ( Waterborne) and polyester wood coatings (PE) several categories. Among them, polyurethane paint has the highest proportion, followed by nitro, UV, alkyd, water-based and polyester paints. In the field of furniture wood coatings, nitro lacquers have been gradually replaced by water-based coatings. Waterborne systems will focus on acrylic ...
