Problems solved by technology

However, there are many disadvantages in water-based wood lacquers at present, one of which is that the yellowing resistance of water-based wood lacquers is not as good as that of traditional artificial wood lacquers because of its non-toxicity.

Embodiment 1

[0015] The invention is an anti-yellowing environmental protection water-based wood paint, which is prepared from the following raw materials in weight ratio:

[0016] Neopentyl glycol diethoxy diacrylate 24, sodium lauryl polyoxyethylene ether sulfate 2, polyether modified polydimethylsiloxane 3, talcum powder 2, nano-montmorillonite 1, cellulose hydroxyethyl Base ether 4, sodium dioctyl sulfosuccinate 7, polyoxyethylene cetyl stearyl diether 12, dihydroquinoline 3, amide wax emulsion 16, feldspar powder 4 and water 40.

[0017] Concrete preparation steps are as follows:

[0018] Each raw material component is added into a high-speed mixer according to the weight ratio, and after high-speed mixing for 40 minutes, the slurry released from the high-speed mixer is put into a colloid mill and circularly ground for 40 minutes to obtain the water-based wood varnish.

Embodiment 2

[0020] The invention is an anti-yellowing environmental protection water-based wood paint, which is prepared from the following raw materials in weight ratio:

[0021] Neopentyl glycol diethoxy diacrylate 35, sodium lauryl polyoxyethylene ether sulfate 8, polyether modified polydimethylsiloxane 6, talcum powder 4, nano-montmorillonite 3, cellulose hydroxyethyl Base ether 10, sodium dioctyl sulfosuccinate 3, polyoxyethylene cetyl stearyl diether 7, dihydroquinoline 1, amide wax emulsion 12, feldspar powder 1 and water 25.

[0022] Each raw material component is added into a high-speed mixer according to the weight ratio, and after high-speed mixing for 50 minutes, the slurry released from the high-speed mixer is put into a colloid mill and circulated for 30 minutes to obtain the water-based wood varnish.

Embodiment 3

[0024] A kind of anti-yellowing environmental protection water-based wood paint of the present invention is prepared from the raw materials of following weight ratio:

[0025] Neopentyl glycol diethoxy diacrylate 28, sodium lauryl polyoxyethylene ether sulfate 5, polyether modified polydimethylsiloxane 4, talcum powder 3, nano-montmorillonite 2, cellulose hydroxyethyl Base ether 8, sodium dioctyl sulfosuccinate 5, polyoxyethylene cetyl stearyl diether 11, dihydroquinoline 2, amide wax emulsion 14, feldspar powder 3 and water 30.

[0026] Concrete preparation steps are as follows:

[0027] Each raw material component is added into a high-speed mixer according to the weight ratio, and after high-speed mixing for 45 minutes, the slurry released from the high-speed mixer is put into a colloid mill and circulated for 35 minutes to obtain the water-based wood varnish.

Abstract

The invention discloses yellowing-resistant and environment-friendly water-borne wood paint, and belongs to the technical field of wood paint. The wood paint is prepared from raw materials in a weightratio as follows: 24-35 of neopentyl glycol diethoxy diacrylate, 2-8 of sodium lauryl polyoxyethylene ether sulfate, 3-6 of polyether-modified polydimethylsiloxane, 2-4 parts of talcum powder, 1-3 parts of nano-montmorillonite, 4-10 parts of cellulose hydroxyethyl ether, 3-7 of dioctyl sodium sulfosuccinate, 7-12 of polyoxyethylene cetyl stearyl diether, 1-3 of dihydroquinoline, 12-16 of amide wax emulsion, 1-4 of feldspar powder and 25-40 of water. Compared with existing water-borne wood paint, the water-borne wood paint is high in paint film transparency, good in dispersibility, healthy andenvironmentally friendly and has excellent properties of yellowing resistance, water resistance and corrosion resistance, and the service life of wooden furniture can be prolonged remarkably.

Description

technical field [0001] The invention relates to the technical field of wood lacquer, in particular to an anti-yellowing environmental protection water-based wood varnish. Background technique [0002] Traditional artificial wood paints such as polyurethane paint and nitro paint are the mainstream products of wood paint because of their cheap price and convenient construction. However, these traditional wood paints will release a large amount of toxic and harmful solvents and free TDI during and after painting. , and some also contain heavy metals, which do not meet today's environmental protection requirements. The water-based wood paint has made a breakthrough in the environmental protection of the paint, because it uses water as the medium, uses a variety of unsaturated chemical monomers, and forms a thermosetting, high-gloss wood paint under specific process conditions, which is non-toxic and tasteless. , No pollution, water resistance, acid and alkali resistance, easy t...
