[0002] Decorative board is a material that is laid or painted on the surface of a building to decorate and beautify the environment. It is a material that combines materials, craftsmanship, shape design, and aesthetics. It is an important material basis for architectural decoration projects. With the rapid development of society, People's demand for decorative panels on building surfaces is constantly increasing, not only requiring them to be beautiful but also to have the performance of thermal insulation and sound insulation. Therefore, thermal insulation panels are widely used in building materials. The external bonding decorative layer is widely used in architectural decoration because of its beautiful, light, thin and flexible material, which is easy to install. However, due to the low strength of the insulation board itself, the soft porcelain decorative layer has low flexibility and strength. Therefore, the overall compression resistance of the prepared decorative board is low, and the surface of the soft porcelain decorative layer is soft, and it is easy to form scratches under the action of sharp foreign objects during long-term use, which affects the appearance

Embodiment 1

[0040] The specific preparation process of the isolation support layer is as follows:

[0041] Step 1: Add 1kg melamine, 5L water and 1.81kg mass concentration of 16% hydrochloric acid solution into the reactor, heat to 85°C and stir to dissolve it, then cool to 8°C and add 624g mass concentration of 30% hydrochloric acid solution therein Sodium nitrate solution, control the temperature at 12°C and stir vigorously for 5 minutes, then keep the obtained solution at the same temperature and store it for later use, then add 945g of sodium carbonate, 130L of water and 6.09kg of 5-sulfosalicylic acid aqueous solution into the coupling bucket, and stir at the same time Add the above standby solution to it, keep it warm at 15°C for 2h, then add 1.23kg of sodium chloride therein, raise the temperature to 65°C and keep it warm for 5h, then filter and dry to obtain the conjugated sulfosalicylic acid triazine, The reaction structural formula is as follows; The product is carried out infra...

Embodiment 2

[0050] The specific preparation process of the isolation support layer is the same as that of Example 1, and the 5-sulfosalicylic acid used in the preparation process of Step 1 in Example 1 is replaced by p-hydroxysulfonic acid.

[0051] The limiting oxygen index of the isolation support layer is 32.8%, and the tensile strength is 41.36MPa. Add heavy calcium carbonate directly to the polymer. Due to the poor compatibility between the heavy calcium carbonate and the polymer, directly through physical stirring When mixed, the dispersion performance thereof is reduced, thereby affecting the overall tensile strength of the prepared isolation support.

Embodiment 3

[0053] The specific preparation process of the isolation support layer is the same as in Example 1, but the diene-based end-capping flexible agent is not prepared, and the monomer olefin-based sulfosalicylic acid triazine is directly used in the polymerization process in step 4 to carry out free radicals. Polymerization produces polymers.

[0054] The limiting oxygen index of the isolation support layer is 33.6%, and the tensile strength is 40.13MPa. The polymer is prepared by directly using olefinic sulfosalicylic acid triazine as a monomer. The obtained polymer has high rigidity, low flexibility, and good texture. brittle, resulting in a decrease in its tensile strength.

Abstract

The invention discloses a preparation process of a decorative board containing a polyurethane thermal insulation layer. The specific preparation process is as follows: soak the support isolation layer in ethylenediamine solution, remove and wipe the excess ethylenediamine on the surface, and then isolate the support after wiping The layer is fixed under the mold, and then the polyurethane material to be sent is injected into the mold to obtain a thermal insulation support board; the thermal insulation support board is soaked in 3‑(2,3‑glycidyloxy)propyltrimethoxysilane and then taken out and dried , coating a layer of epoxy resin adhesive on the bottom surface of the decorative layer, and then bonding the decorative layer to the surface of the supporting isolation layer of the hydrophobic thermal insulation support board through the epoxy resin adhesive to obtain a decorative board. In the present invention, a high-strength support and isolation layer is arranged between the thermal insulation layer and the soft porcelain decorative layer, so that the strength of the decorative board can be improved, and after a period of use, a new decorative layer can be directly torn off and re-pasted, and the There will be no decorative layer residue on the surface of the rear support isolation layer, which will not affect the secondary paste.
