Problems solved by technology

In its formula, the introduction of cellulose acetate butyrate will greatly increase the viscosity of the system. In this case, it is necessary to add more solvent to dilute to reduce the viscosity, which will lead to waste of solvent and increase VOC emission is not conducive to environmental protection
If no solvent is added to dilute, the paint film will be thicker. The thickening of the paint film will increase the haze, but the light transmittance will decrease sharply, which will reduce the luminous efficiency of the lamp and waste energy.

Embodiment approach

[0037] According to the present invention, the coating composition of the present invention can be obtained by various existing methods, and the present invention has no special requirements. According to a preferred embodiment of the present invention, the method, for example, may include the following steps:

[0038] (1) Weigh the aforementioned solvents as required (such as esters, aromatic hydrocarbons and ketones, specifically butyl acetate, isopropanol, n-butanol, cyclohexanone, xylene, ethylene glycol butyl ether, methyl one or more of the base isobutyl ketone).

[0039] (2) Weigh the required resins (thermoplastic acrylic resins) according to the requirements, and add them to the above-mentioned solvents respectively (the order of addition is arbitrary), and continue to stir for 10-100 minutes before proceeding to the next step.

[0040] (3), according to the requirements, weigh the various fillers required, and add them to the above solution (the order of addition is ...

Embodiment 1

[0054] Use raw material as shown in table 1, prepare lampshade coating according to the following method:

[0055] (1) Weigh the above-mentioned mixed solvent as required (see Table 1 for the type and dosage), stir (500r / min) under the high-speed disperser, and proceed to the next step after 10 minutes.

[0056] (2) Weigh the required resins according to the requirements (see Table 1 for product grades and dosages), and add them to the above-mentioned mixed solvents (in any order), and continue to stir for 13 minutes before proceeding to the next step.

[0057] (3) Weigh the required matting powder, polyamide wax micropowder (PA wax powder), titanium dioxide and fluorescent whitening agent (see Table 1 for product grade and dosage) according to the requirements, and add them to the solution of step (2) In (arbitrary order of adding), continue to stir for 5 minutes and proceed to the next step.

[0058](4) Take the required additives according to the requirements (see Table 1 ...

Embodiment 2-5

[0065] The preparation method is the same as that of Example 1, except that the types and amounts of substances are different, see Table 1 for details. The obtained coating composition was sprayed, and the spraying method was consistent with that of Example 1, and various performance tests were carried out, and the results are shown in Table 2.

Abstract

The invention provides a coating composition. The coating composition contains a thermoplastic acrylic acid resin, a filling material and one or more solvent, wherein the filling material contains titanium dioxide and polyamide wax micro-powder (PA wax powder). The invention also provides application of the coating composition in lampshade coatings. The coating composition can be utilized for preparation of lampshade coatings, has high transmittance and scattering effects, can effectively reduce radiation intensity of a unit area, is suitable for lampshades prepared from various glass and plastic materials such as PC, ABS, PMMA and the like, and realizes high lampshade haze. The coating composition has uniform coating effects and very high transmittance and haze, wherein the transmittance and the haze can both reach 90%, has small coating thickness, saves raw materials, can produce a strong adhesive force on glass and plastic, has good weatherability, can be cured at an environmental temperature, and does not yellow and fall off.

Description

technical field [0001] The invention relates to a paint composition and its application in lampshade paint. Background technique [0002] LED lighting facilities are generally composed of multiple small strong point light sources, and the light emitted by these strong point light sources will strongly stimulate people's eyes. In order to reduce this stimulation, it is usually necessary to make the lampshade have a strong scattering effect, which can scatter the parallel emitted light to all directions, thereby making the light soft. The effect reflected in human vision is: the original strong emitting point light source has completely disappeared, replaced by a uniformly luminous lampshade spherical surface. [0003] The current lampshade coatings are mostly made for ordinary lamps, and the scattering effect is poor. It has no obvious effect on LED lamps with strong emitting point light sources. Generally, the dazzling point light sources inside the lampshade can still be s...
