Formaldehyde-resistance odor-removing total-effect environmental-friendly water-borne wood white paint and preparation technology thereof

Abstract

The invention discloses a formaldehyde-resistance odor-removing total-effect environmental-friendly waterborne wood white paint and a preparation technology thereof. The wood white paint comprises the following components in percentage: 25 to 30 percent of formaldehyde removing emulsion, 10 to 15 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 nano TiO2 photocatalyst, 15 to 25 percent of calcium carbonate and pigment and filler, 0.1 to 0.3 percent of delustering powder, 0.1 to 0.2 percent of antifoaming agent, 0.5 to 1.5 percent of dispersing agent, 0.2 to 0.5 percent of anti-sedimentation agent and 18 to 38 percent of water and auxiliaries. The preparation technology comprises the following steps of: firstly adding the core-shell pure acrylic acid emulsion and the 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, scratch resistance wax additive, the water, thedispersing agent, the delustering agent, the antifoaming agent, the anti-sedimentation agent and other components; after dispersing for 40 minutes at an intermediate speed, sampling and detecting thefineness and the viscosity of a finished product; and carrying out filtering, canning and packaging on the finished product.

Description

technical field [0001] The invention relates to a water-based wood white paint; in particular, the invention relates to a formaldehyde-resistant, deodorizing, full-effect, environmentally friendly water-based wood white paint, and also relates to a preparation technology for the formaldehyde-resistant, odor-free, full-effect, environmentally friendly water-based wood white paint. 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...

Problems solved by technology

In terms of furniture export, my country's current policies and regulations do not clearly stipulate that solvent-based coatings cannot be used for wooden furniture, but the United States, the European Union and Japan have issued relevant regulations restricting and prohibiting the use of solvent-based wood coatings

[0003] During the use of solvent-based wood coatings, due to the release of organic substances, it has brought health hazards to wood furniture manufacturers and users
