Embodiment 1

[0039] Get each component by the weight shown in embodiment 1 in table 1, prepare according to the following steps:

[0040] Step 1: Weigh 16kg of GK570 fluororesin and add it to the dispersion tank, then add 0.5kg BYK-163 dispersant, disperse at medium speed (600-800RMP) for 3 minutes, then add 0.2kg BYK-066N defoamer, disperse at medium speed for 5 minutes, then Add 0.6kg SD-1 anti-sedimentation agent, disperse at high speed (1200-1500RMP) for 5 minutes, then slowly add 20kgRCL-595 titanium dioxide under stirring at low speed (about 400RMP), and disperse at high speed for 15-20 minutes until the fineness is less than or equal to 25μm .

[0041] Step 2: Add the remaining 34kg GK570 fluororesin, 5kg butyl acetate, 7kg propylene glycol methyl ether acetate, and 3kg dimethyl valerate to the titanium dioxide slurry in step 1, and stir at a low speed (about 400 RMP) for 10-15 minutes. Then add 2kg of SY7000 matting powder and disperse at high speed (1200-1500RMP) for 15 minutes t...

Embodiment 2

[0047] According to the weight shown in Example 2 in Table 1, each component was taken, and the method described in Example 1 was repeated to prepare the main agent, curing agent and thinner of the orange-grain effect fluorocarbon paint. According to the weight ratio of main agent: curing agent: diluent = 106.7:8.7:25, mix evenly, the viscosity is 34s, and then apply and dry according to the method of Example 1. The performance testing results are shown in the corresponding data of Example 2 in Table 2.

Embodiment 3

[0049] According to the weight shown in Example 3 in Table 1, each component was taken, and the method described in Example 1 was repeated to prepare the main agent, curing agent and diluent of the orange-grain effect fluorocarbon paint. According to the weight ratio of main agent: curing agent: diluent = 124.7:12.4:35, mix evenly, viscosity is 32s, then apply and dry according to the method of Example 1. The performance testing results are shown in the corresponding data of Example 3 in Table 2.

[0050]The orange-grain effect fluorocarbon paint obtained above can also be toned, and a proper amount of special color paste for fluorocarbon paint can be added to obtain orange-grain effect fluorocarbon paints of various required colors. Matting agent can be added according to needs, if no matting agent is added, bright white fluorocarbon paint will be obtained.

[0051] The orange grain effect fluorocarbon paint of the invention only needs to be cross-linked and cured at room te...

Abstract

The invention relates to an orange-peel-effect fluorocarbon paint, and a preparation method and application method thereof. The main agent is composed of the following components in parts by weight: 50.0-60.0 parts of fluororesin, 0.5-1.5 parts of dispersing agent, 0.6-1.0 part of anti-settling agent, 20.0-30.0 parts of rutile titanium white, 0.2-0.4 part of defoaming agent, 15.0-25.0 parts of mixed solvent, 0-6 parts of matting powder and 0.4-0.8 part of orange peel agent. The curing agent is composed of the following components in parts by weight: 80.0 parts of HDI (hexamethylene diisocyanate) curing agent and 20.0 parts of butyl acetate. The weight ratio of the hydroxyl value of the fluororesin to the NCO content of the curing agent (OH:NCO) is 1:(1.05-1.15). The fluorocarbon paint can directly display the realistic orange peel effect, and can select the thickness, brightness and matting degree of the orange peel according to needs, thereby omitting the galling paint in the prior art and saving the material cost and procedure.

Description

technical field [0001] The invention relates to a fluorocarbon paint, in particular to a normal temperature cross-linking type orange effect fluorocarbon paint and a preparation method and application method thereof. Background technique [0002] The coating of room temperature cross-linked fluorocarbon paint on the exterior wall of buildings has experienced the extreme coating process of imitating aluminum plate effect. Due to the current situation of construction management of coating sites in my country, it is difficult to strictly implement the construction ratio and construction technology. Coating cracking is common, causing great troubles to the fluorocarbon paint industry. Starting from changing the construction process, people apply fluorocarbon topcoats on various textured coatings to obtain various personalized texture effects, solve the problem of coating cracking, and maintain the advantages of excellent weather resistance of fluorocarbon coatings. . However, i...
