Problems solved by technology

[0003] However, the current daylighting panels are exposed to sunlight for a long time, so that the ultraviolet rays in the sunlight will cause the surface of the daylighting panels to turn yellow. Therefore, we propose a high oxygen index daylighting panel that can improve the yellowing phenomenon. solve the above problems

preparation example Construction

[0031] The preparation method of resin coating comprises the following steps:

[0032] S1, take the raw material according to the amount, set aside;

[0033] S2. Put composite epoxy resin, calcium carbonate, gemini surfactant, cyclohexanone and xylene into the reaction kettle, and start to stir it evenly with a magnetic rod at a speed of 800r / min after heating up to 35°C for 2.5 hours ;

[0034] S3. During the stirring process of S2, add polymeric light stabilizer, flame retardant, modified anti-yellowing agent and modified antioxidant at the 16th minute after starting stirring, and then continue to stir evenly at a speed of 1300r / min , after the stirring is completed, wait for it to cool to room temperature to obtain a resin coating.

[0035] Finally, apply the resin paint evenly on the surface of the lighting board and let it dry.

Embodiment

[0037] In embodiment one~embodiment three, all used identical formulation raw material to prepare this resin coating, and the consumption of formulation raw material in each embodiment is as shown in the table below:

[0038]

[0039]

[0040] The step of preparing resin coating by above-mentioned formula is as follows:

[0041] S1, take the raw material according to the amount, set aside;

[0042] S2. Put composite epoxy resin, calcium carbonate, gemini surfactant, cyclohexanone and xylene into the reaction kettle, and start to stir it evenly with a magnetic rod at a speed of 800r / min after heating up to 35°C for 2.5 hours ;

[0043] S3. During the stirring process of S2, add polymeric light stabilizer, flame retardant, modified anti-yellowing agent and modified antioxidant at the 16th minute after starting stirring, and then continue to stir evenly at a speed of 1300r / min , after the stirring is completed, wait for it to cool to room temperature to obtain a resin coa...

Abstract

The invention relates to the technical field of daylighting panels, in particular to a high-oxygen-index daylighting panel which comprises a base plate and a resin coating, and the surface of the base plate is coated with the resin coating. The resin coating is prepared from the following raw materials in parts by weight: 20-45 parts of composite epoxy resin, 12-20 parts of calcium carbonate, 9-12 parts of a gemini surfactant, 3-7 parts of talc, 3-7 parts of cyclohexanone, 3-7 parts of a polymeric light stabilizer, 5-9 parts of a flame retardant, 12-16 parts of xylene, 3-7 parts of a modified anti-yellowing agent and 3-7 parts of a modified antioxidant. The preparation method of the resin coating comprises the following steps: S1, weighing the raw materials by weight for later use; and S2, putting the composite epoxy resin, calcium carbonate, a gemini surfactant, cyclohexanone and xylene into a reaction kettle. The anti-yellowing agent and the antioxidant are added into the formula at the same time, and the anti-yellowing effect of the daylighting panel in daily use can be remarkably improved through cooperative use of the anti-yellowing agent and the antioxidant.

Description

technical field [0001] The invention relates to the technical field of daylighting panels, in particular to high oxygen index daylighting panels. Background technique [0002] The daylighting board is a daylighting skylight with a hole reserved on the roof panel, a well wall around the hole, and a flat light-transmitting material installed on it. Under normal conditions, the intensity of direct radiation is 4 to 7 times that of diffuse radiation, and the lighting panel mainly uses direct light. The outdoor direct radiation is reflected by the lighting panel to the indoor ceiling through the small upper window opening, and is scattered and reflected by the ceiling to uniformly illuminate the farther away from the window. In the case of the same window area, the place far away from the window is fully illuminated, which improves the uniformity of indoor lighting and improves visual comfort; the upper opening area is small, although reflected radiation enters, it will not Ser...
