[0032] The present invention also provides the preparation technology of acrylic primer:

[0033] S100, make the base material of the primer with the above base material formula, and stir for 5 minutes at a speed of 400-600 revolutions per minute;

[0034] S200. Add halogen-free color paste with a content not higher than 25% (weight ratio) while stirring according to the color required by the paint user;

[0035] S300, after feeding and color matching, continue to stir for 30 minutes to complete the primer produced with the base material formula of the present invention.

[0036] In the preparation process of the present invention, the following steps may also be included after step S200:

[0037] S210, adding aluminum paste and (or) pearl powder with a halogen-free content not higher than 8% (by weight).

[0038] The main application process of the acrylic primer product produced with the acrylic primer base material formula of the present invention:

[0039] Surface treat...

Embodiment 1

[0055] Polystyrene modified methyl methacrylate 62.5%;

[0056] 80-200 seconds nitrocellulose solution 27.5%;

[0057]Cyclohexanone 2.5%;

[0058] Toluene 5.0%;

[0059] Ethyl acetate 2.0%;

[0060] Polyacrylic acid leveling agent (BYK-358) 0.5%.

[0061] Use the above-mentioned base material formula to make the base material of the primer, and stir at a speed of 400-600 rpm for 5 minutes; while stirring, add a halogen-free color paste with a weight ratio not higher than 25%, and the color matching is completed Then continue to stir for 30 minutes and have just completed the primer produced with the base material formula of the present invention. The acrylic primer produced by the base material formula of this embodiment is used in conjunction with spraying diluent and ultraviolet radiation curing topcoat, sprayed on polycarbonate plastic, and dried and cured.

Embodiment 2

[0063] Polystyrene modified methyl methacrylate 60.0%;

[0064] 80-200 seconds Nitrocellulose solution 30.0%;

[0065] Cyclohexanone 5.0%;

[0066] Toluene 1.0%;

[0067] Ethyl acetate 3.9%;

[0068] Polyacrylic acid leveling agent (BYK-358) 0.1%.

[0069] Use the above-mentioned base material formula to make the base material of the primer, and stir at a speed of 400-600 rpm for 5 minutes; while stirring, add a halogen-free color paste with a weight ratio not higher than 25%, and the color matching is completed Then continue to stir for 30 minutes and have just completed the primer produced with the base material formula of the present invention. The acrylic primer produced by the base material formula of this embodiment is used in conjunction with spraying diluent and ultraviolet radiation curing topcoat, sprayed on polycarbonate plastic, and dried and cured.

Abstract

The invention discloses a method for producing an acrylic acid priming paint base-material and an acrylic acid priming paint. The polystyrene modified methyl methacrylate and 80-200 seconds nitro cellulose liquid are taken as the main components in an acrylic acid priming paint base-material formula, and a solvent and a leveling agent are also concluded. The acrylic acid priming paint base-material formula accords with the halogen-free requirement of the cell phone industry on paint (bromine content in the formula is less than 900ppm, chlorine content in the formula is less than 900ppm, the total content of bromine and chlorine is less than 1500ppm). The acrylic acid priming paint produced by the base-material formula is matched with a spraying diluent and an ultraviolet radiation solidification topcoat to spray on the polycarbonate plastics, the dried and solidified coating has excellent water-boiling resistance, the coating has no foaming, no cracking and no discoloration after being boiled for 30 minutes in boiling water at the temperature of 100 DEG C.

Description

technical field [0001] The invention relates to the field of paint making, in particular to an acrylic primer base material and a preparation method of the acrylic primer. Background technique [0002] At present, the plastic casing and buttons of mobile phones are painted with halogen-containing primers and UV radiation-curable topcoats, and some are coated with halogen-free primers and UV radiation-curable topcoats. With the environmental management of some foreign mobile phone manufacturers The limitation of substances has clearly stipulated the halogen content in the mobile phone coating formula, requiring the bromine content in the mobile phone coating formula to be less than 900ppm, the chlorine content to be less than 900 ppm, and the total content of bromine and chlorine to be less than 1500 ppm. Some mobile phone manufacturers are no longer in compliance; so far, no halogen-free primer and UV-curable topcoat have been found that can pass the test of boiling at 100°C...
