Embodiment 1

[0019] Add 36 kg of ester solvent without stirring, and then add 23 kg of nitrocellulose. After the nitrocellulose is completely submerged, disperse at a speed of 600-1000 rpm for 15-20 minutes until the nitrocellulose is completely dissolved. Then add 10 kg of maleic acid modified rosin resin, and disperse for 15 to 20 minutes at a rotating speed of 800 to 1000 rpm until the rosin resin is completely dissolved. Add 21 kg of modified saturated polyester resin and 2 kg of dioctyl phthalate at a rotating speed of 300-500 rpm and stir evenly at a rotating speed of 800-1000 rpm. Then add 6 kg of zinc stearate and 2 kg of talcum powder at a speed of 300-500 rpm, gradually increase the speed to 800-1200 rpm, and disperse at a high speed for about 20-30 minutes until the fineness is 40-50 microns , adjust the paint viscosity to 100 ~ 135KU / 30 ℃ (STM viscometer) to get the finished product. The physical and chemical test results are shown in Table 1.

Embodiment 2

[0021] Add 38.3 kg of ester solvent without stirring, and then add 22.5 kg of nitrocellulose. After the nitrocellulose is completely submerged, disperse at a speed of 600-1000 rpm for 15-20 minutes until the nitrocellulose is completely dissolved. Then add 9.5 kg of maleic acid modified rosin resin, and disperse for 15 to 20 minutes at a rotating speed of 800 to 1000 rpm until the rosin resin is completely dissolved. Add 20.5 kg of modified saturated polyester resin and 1.8 kg of dioctyl phthalate at a rotating speed of 300-500 rpm and stir evenly at a rotating speed of 800-1000 rpm. Then add 5.5 kg of zinc stearate and 1.9 kg of talcum powder at a speed of 300-500 rpm, gradually increase the speed to 800-1200 rpm, and disperse at a high speed for about 20-30 minutes until the fineness is 40-50 microns , adjust the paint viscosity to 100 ~ 135KU / 30 ℃ (STM viscometer) to get the finished product. The physical and chemical test results are shown in Table 1.

Embodiment 3

[0023] Add 40.5 kg of ester solvent without stirring, and then add 22 kg of nitrocellulose. After the nitrocellulose is completely submerged, disperse at a speed of 600-1000 rpm for 15-20 minutes until the nitrocellulose is completely dissolved. Then add 9 kg of maleic acid modified rosin resin, and disperse for 15 to 20 minutes at a rotating speed of 800 to 1000 rpm until the rosin resin is completely dissolved. Add 20 kg of modified saturated polyester resin and 1.7 kg of dioctyl phthalate at a rotating speed of 300-500 rpm and stir evenly at a rotating speed of 800-1000 rpm. Then add 5 kg of zinc stearate and 1.8 kg of talcum powder at a speed of 300-500 rpm, gradually increase the speed to 800-1200 rpm, and disperse at a high speed for about 20-30 minutes until the fineness is 40-50 microns , adjust the paint viscosity to 100 ~ 135KU / 30 ℃ (STM viscometer) to get the finished product. The physical and chemical test results are shown in Table 1.

Abstract

The invention discloses multi-layer recoating, high transparent, quick drying and superior buffing nitryl transparent primer. The nitryl transparent primer comprises components with the parts by weight being as follows: 36 to 45 parts of ester solvent, 20 to 25 parts of nitro cotton, 18 to 22 parts of maleic modified abietic resin, 1.5 to 2.0 parts of dicapryl phthalate, 4 to 7 parts of zinc stearate, and 1.5 to 2.3 parts of talcum powder. The multi-layer recoating, high transparent, quick drying and superior buffing nitryl transparent primer has the characteristic of keeping the high transparency after being recoated, and has the characteristics of quick drying and superior buffing at the same time. Moreover, the product has the advantages that the product formula is simple, the cost is inexpensive, and the performance-price ratio is high.

Description

technical field [0001] The invention relates to the field of organic macromolecular materials, in particular to a multi-layer recoated high-transparency, fast-drying and easy-polishing nitro transparent primer. Background technique [0002] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. [0003] In modern home decoration, more and more people like to be close to nature, so that their homes can keep as much natural atmosphere as possible. People wish to make their furniture, floors and other decorations keep their original texture structure and color to the greatest extent while protecting their furniture, floors and other decorations. And with the accelerated pace of modern people's life, more...
