Problems solved by technology

4. Wooden substrates contain turpentine that has not been removed and treated, and the paint film will seep out over time, causing local cracks
5. The moisture content of the wood is too high, which will cause cracking due to deformation over time; 6. Too much curing agent is added, or the wrong curing agent is used; 7. The construction is too thick; 8. The construction environment is harsh, the temperature difference is large, the humidity is large, and the paint film Expansion and contraction by cold and heat, causing cracks

Embodiment 1

[0027] A paint containing purple fluorescent substance is characterized in that the weight ratio of its components is: 6.5% calcium sulfide, 3% magnesium sulfide, 0.8% sodium sulfide, 0.1% strontium nitrate, 12% wax ester, Tung oil 20%, epoxy resin 10%, modified alkyd resin 3%, palm olein 12%, methacrylic resin 5%, semi-matt acrylic pigment 1%, new photoinitiator 3%, polyvinyl alcohol 5% butyral, and the rest are thinners; the novel photoinitiator is prepared by the following method: the following are expressed in mole fractions, adding 1 part of 4-hydroxybenzophenone and 1 to 3 parts of formaldehyde into the reaction vessel , after mixing evenly, add 0.0102 parts of alkali as a catalyst, under the condition of stirring, heat and keep slightly boiling at 90°C for 1h; then raise the temperature to 140°C, carry out the decompression reaction for 10 minutes, cool to 90°C after the reaction to collect the product, The product was added to 10 parts of deionized water for precipitat...

Embodiment 2

[0037] A paint containing purple fluorescent substance is characterized in that: its component weight ratio is: 6% calcium sulfide, 3% magnesium sulfide, 1% sodium sulfide, 0.08% strontium nitrate, 17% wax ester, Tung oil 30%, epoxy resin 16%, modified alkyd resin 6%, palm olein 16%, methacrylic resin 5-8%, semi-matt acrylic pigment 3%, new photoinitiator 6%, poly Vinyl butyral 10%, the rest are thinners; the novel photoinitiator is prepared by the following method: the following are expressed in mole fractions, 1 part of 4-hydroxybenzophenone and 3 parts of formaldehyde are added to the reaction vessel , after mixing evenly, add 0.012 parts of alkali as a catalyst, under stirring conditions, heat and keep slightly boiling (99°C) for 3 hours; then raise the temperature to 160°C, carry out a decompression reaction for 15 minutes, cool to 110°C after the reaction and collect product, the product was added to 20 parts of deionized water for precipitation, and a novel photoinitiat...

Abstract

The invention relates to a chemical industrial product, in particular to a coating containing purple fluorescent substances. The coating is prepared from, by weight, 6%-6.5% of calcium sulphide, 2.5%-3% of magnesium sulfide, 0.8%-1% of sodium sulphide, 0.08%-0.1% of strontium nitrate, 12%-17% of wax ester, 20%-30% of China wood oil, 10%-16% of epoxy resin, 3%-6% of modified alkyd resin, 12%-16% of palm olein ester, 5%-8% of methacrylic resin, 1%-3% of semi-matte acrylic paint, 3%-6% of novel photoinitiator, 5%-10% of polyvinyl butyral and the balance thinner. The coating can absorb light and emit purple light in the dark environment, light resistance and weather resistance are good, tinting strength and covering power are high, adhesive force is high, the coating is not easy to crack after use and can be used for objects such as guide boards, outdoor advertisements, roads at night and barrier signs.

Description

technical field [0001] The invention relates to a chemical industry product, in particular to a paint containing purple fluorescent substances. Background technique [0002] Cracks of different depths and sizes appear on the surface of the paint film. If the underlying surface can be seen from the cracks, it is called "cracking". [0003] Reasons for the problem: 1. The primer and topcoat are not compatible, and the coating film is affected by external influences (mechanical action, temperature change, etc.) to produce shrinkage stress, causing cracks or cracks in the paint film. 2. Apply (spray, brush, roll) the topcoat before the primer is completely dry, or the first topcoat is too thick, and then apply the second topcoat before it is completely dry, so that the inside and outside of the two layers of paint are inconsistent. 3. Interior paint is used for outdoor or metal surface primer for wood. 4. If the wooden substrate contains turpentine and has not been removed and...
