Embodiment 1

[0028]

[0029]

[0030] Embodiment one preparation mode:

[0031] Step 1: Stir and dissolve tripropylene glycol diacrylate, trimethylolpropane triacrylate and photoinitiator at a temperature of 45 degrees.

[0032] Step 2: Add polyurethane acrylic resin and epoxy acrylic resin to the prepared mixture in sequence and stir to disperse evenly.

[0033] Step 3: Divide the filling powder into three equal parts and add in batches, and make it completely dispersed evenly. Until there is no suspension or sedimentation.

[0034] Step 4: Stir the formaldehyde-removing additive, defoaming additive, and hydroxyethyl methacrylate to disperse evenly, then add it to the previously dispersed mixture, and stir evenly until there is no suspension or precipitation.

Embodiment 2

[0036]

[0037] Embodiment two preparation methods:

[0038] Step 1: Stir and dissolve 1,6-hexanediol diacrylate, trimethylolpropane triacrylate and a photoinitiator at a temperature of 45 degrees.

[0039] Step 2: Add polyurethane acrylic resin and epoxy acrylic resin to the prepared mixture in sequence and stir to disperse evenly.

[0040] Step 3: Divide the filling powder into three equal parts and add in batches, and make it completely dispersed evenly. Until there is no suspension or sedimentation.

[0041] Step 4: Stir the formaldehyde-removing additive, defoaming additive, and hydroxyethyl methacrylate to disperse evenly, then add it to the previously dispersed mixture, and stir evenly until there is no suspension or precipitation.

Abstract

The invention discloses a novel photo-curing formaldehyde removing environment-friendly coating and a preparation method of the novel photo-curing formaldehyde removing environment-friendly coating. The novel photo-curing formaldehyde removing environment-friendly coating comprises, by weight, 15-25% of polyurethane acrylic resin, 20-30% of epoxy acrylic resin, 1-10% of hydroxyethyl methylacrylate, 20-30% of tripropylene glycol diacrylate, 10-20% of trimethylolpropane trimethylolpropane triacrylate, 6-12% of photoinitiator, 5-15% of formaldehyde removing assistant, 2-5% of defoaming assistant and 5-15% of filling powder. The novel photo-curing formaldehyde removing environment-friendly coating prepared with the formula and the preparation method has the good formaldehyde purification performance and the good formaldehyde purification effect durability.

Description

technical field [0001] The invention relates to an architectural coating and a preparation method thereof, in particular to a light-curing formaldehyde-removing environmental protection coating and a preparation method thereof. Background technique [0002] Formaldehyde, with the molecular formula HCOH, is the simplest form of aldehyde and is usually a flammable, colorless and irritating gas. Soluble in water, alcohol and ether. 37% formaldehyde solution is commonly known as formalin, which is a biological preservative for corpses. It is specially used for anti-corrosion and even anti-moth. Formaldehyde is often widely used in consumer goods, resins and adhesives, etc., and is also often used in various types of wood-based panels. , Paints, coatings and wallpaper manufacturing, especially wooden decoration uses a large number of wood core boards, laminated boards and other boards. In my country's list of priority control of toxic chemicals, formaldehyde ranks second. The W...
