Problems solved by technology

[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 build

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 plate containing a polyurethane thermal insulation layer. The preparation process comprises the following specific steps that a support isolation layer is soaked in an ethylenediamine solution, then the support isolation layer is fished out to wipe off redundant ethylenediamine on the surface, then the wiped support isolation layer is fixed below a mold, and a polyurethane material to be foamed is injected into the mold to obtain a thermal insulation support plate; and the thermal insulation support plate is soaked in 3-(2, 3-epoxypropoxy) propyltrimethoxysilane and then fished out to be dried, the bottom face of the decorative layer is coated with a layer of epoxy resin adhesive, then the decorative layer is bonded to the surface of the support isolation layer of the hydrophobic thermal insulation support plate through the epoxy resin adhesive, and the decorative plate is obtained. According to the preparation process, thehigh-strength support isolation layer is arranged between the thermal insulation layer and the soft porcelain decoration layer, the strength of the decorative plate can be improved, the decoration layer can be directly torn down after being used for a period of time, a new decoration layer is pasted again, no decoration layer remains on the surface of the torn-down supporting isolation layer, andsecondary pasting is not affected.

Description

technical field [0001] The invention belongs to the field of decorative materials, and relates to a preparation process of a decorative board containing a polyurethane thermal insulation layer. Background technique [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 ins...
