Figure BDA0002290431410000111
As can be seen from the data in Table 1, compared with the daylighting panels of comparative examples 1 to 10, the daylighting panels of examples 1 to 7 have significantly improved temperature resistance, good heat resistance, good thermal stability and good light transmittance, the temperature resistance is-80 ℃ to 180 ℃, the thermal deformation temperature is as high as 229 ℃, and the thermal expansion coefficient is as low as 2.0 x 10-5m/m/DEG C, the light transmittance is up to 89.5 percent, meanwhile, the mechanical property of the daylighting panel is greatly improved, the bending strength is up to 279MPa, the tensile strength is up to 215MPa, and the Rockwell hardness is up to 68 HBa. Therefore, the daylighting panels prepared in embodiments 1 to 7 of the invention have good weather resistance and heat stability, high strength, good toughness and good service performance, and effectively solve the technical problems of low temperature resistance limit and poor weather resistance of the daylighting panels in the prior art. The formula and the preparation method of the embodiment 5 are relatively better embodiments of the invention, and the prepared daylighting panel has better comprehensive performance.

The ceramic fiber is formed by high-temperature sintering after mixing and spinning aluminum oxide, silicon oxide, titanium oxide, zirconium oxide, magnesium oxide and cerium oxide, has high strength and thermal stability, and simultaneously has low thermal conductivity and high specific heat, so that the ceramic fiber is added into the daylighting panel and is mutually compatible with the glass fiber, the tensile strength, hardness and thermal stability of the daylighting panel are obviously improved, the strength and hardness of the daylighting panel are high, the thermal deformation temperature is high, the thermal expansion coefficient is small, the mutual compatibility of the zirconium oxide, the magnesium oxide and the cerium oxide improves the weather resistance of the daylighting panel further, the temperature resistance limit of the daylighting panel is improved, and the service life of the daylighting panel is prolonged.
Compared with the daylighting panel of the embodiment 5, the daylighting panels of the comparative examples 3 and 4 have relatively poor performances because the raw materials of the daylighting panel of the comparative example 3 are not added with epoxy resin, acrylic emulsion, N-methyl pyrrolidone, sodium cocoyl methyl taurate and ethylhexyl methoxycinnamate, and the components in the raw materials are directly mixed in the production process of the daylighting panel of the comparative example 4, which means that the N-methyl pyrrolidone, the sodium cocoyl methyl taurate and the ethylhexyl methoxycinnamate are firstly added into the acrylic emulsion, heated to 80-85 ℃, added with the epoxy resin, uniformly mixed to obtain a mixed emulsion, coated on the surface of a mixed fiber obtained by mixing ceramic fibers and glass fibers, dried to obtain a second mixed material, then added into the first mixed material to be cured and molded, so that the compatibility between the mixed fiber and a resin matrix is remarkably improved, the dispersion of the mixed fibers in the resin matrix is more uniform, so that the reinforcing effect of the mixed fibers is improved, the weather resistance of the daylighting panel is obviously improved, and the mechanical properties such as tensile strength and hardness are further improved.
Compared with the daylighting panel of example 5, the daylighting panels of comparative examples 5-10 all have reduced tensile strength, babbitt hardness and heat distortion temperature, because the mass ratio of the promoter triisopropanolamine to cobalt isooctanoate in the daylighting panel raw material of comparative example 5 is 2: 7, aluminum sulfate is not added, and the mass ratio of aluminum sulfate as an accelerator to cobalt isooctanoate in the raw material of the daylighting panel of the comparative example 6 is 1: 7, triisopropanolamine is not added, and the mass ratio of the accelerator to the aluminum sulfate in the raw material of the daylighting panel in the comparative example 7 is 2: 1, the cobalt isooctanoate is not added, and the accelerator in the daylighting panel raw material of the comparative example 8 is triisopropanolamine, aluminum sulfate and the cobalt isooctanoate with the mass ratio of 1: 1: 7, the accelerator in the raw material of the daylighting panel of comparative example 9 is triisopropanolamine, aluminum sulfate and cobalt isooctanoate with the mass ratio of 2: 3: 7, the accelerator in the raw material of the daylighting panel of the comparative example 10 is triisopropanolamine, aluminum sulfate and cobalt isooctanoate with the mass ratio of 2: 1: 5, the addition of the accelerator is illustrated, the curing and forming process of the daylighting panel is accelerated, and the mass ratio of triisopropanolamine, aluminum sulfate and cobalt isooctanoate is 2: 1: the mixture of 7 is used as an accelerant and is matched with a curing agent, so that the curing effect is obviously improved, the tensile strength, the Babbitt hardness and the thermal deformation temperature of the daylighting panel are improved, the addition of triisopropanolamine and aluminum sulfate has a synergistic effect on cobalt iso-octoate, the promotion effect of cobalt in the cobalt iso-octoate is increased, and the triisopropanolamine, the aluminum sulfate and the cobalt iso-octoate in a specific ratio are mutually compatible, so that the effect of the accelerant is better exerted, a more efficient curing system is formed, and the performance of the daylighting panel is improved.
