Embodiment 1

[0043] Mix and dissolve 100 parts of polypropylene and 70 parts of paraffin to form a homogeneous solution, and directly coat it on the template to form a flat film with a thickness of 1 mm. The flat film is immersed in cold water to cool, and the system undergoes liquid-liquid phase separation to form a polymer Cured film (such as Figure 1-2 shown).

[0044] The paraffin wax is evaporated by evaporation, and the evaporation temperature is 35°C ± 1°C, so that micropores (such as Figure 3-4 shown), that is, to obtain a core plate material with a micropore size of 0.1 μm, a porosity of 70%, and a thickness of 1 mm.

[0045] The upper and lower sides of the above-mentioned core board are covered with color steel plates to make a hollow sandwich board. Two-liquid mixed hardening glue is used to make the sandwich panel, and the dosage is 200g / m 2 .

Embodiment 2

[0047] Mix and dissolve 100 parts of polyester and 60 parts of soybean oil to form a homogeneous solution, and directly coat the template to form a flat film with a thickness of 3mm. The flat film is immersed in propylene glycol to cool, and the system undergoes liquid-liquid phase separation, and the polymer will Cured into a film.

[0048] The soybean oil is evaporated by evaporation, and the evaporation temperature is 22°C±1°C, so that micropores are formed on the surface of the film, and a sandwich core with a micropore size of 0.1μm, a porosity of 60%, and a thickness of 3mm is obtained. The core material of the board.

[0049] The upper and lower sides of the above-mentioned core plate are covered with stainless steel plates to make a hollow sandwich plate. Two-liquid mixed hardening glue is used to make the sandwich panel, and the dosage is 220g / m 2 .

Embodiment 3

[0051] Mix and dissolve 100 parts of polymethyl methacrylate and 50 parts of diphenyl ether to form a homogeneous solution, and directly coat it on the template to form a flat film with a thickness of 5 mm. The flat film is immersed in ethane to cool, and the system generates liquid- The liquid phase separates to form a polymer cured film.

[0052] The diphenyl ether is extracted with toluene by the extraction method, so that micropores are formed on the surface of the prepared membrane, and a core plate material of a sandwich plate with a micropore size of 1 μm, a porosity of 50%, and a thickness of 5 mm is obtained.

[0053] The upper and lower sides of the above-mentioned core board are covered with polypropylene board to form a hollow sandwich board. Two-liquid mixed hardening glue is used to make the sandwich panel, and the dosage is 240g / m 2 .

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a core plate as well as a preparation method and uses thereof. The core plate comprises the following components in parts by weight: 100 parts of polymer and 20-80 parts of auxiliary agent. The core plate in a pore structure is manufactured, the core plate is uniform in aperture distribution and high in porosity, and the shape and thickness of the manufactured core plate also can be adjusted according to requirements. The core plate manufactured with the method is manufactured into a hollow board; besides the basic performances of an ordinary hollow board such as heat insulation, heat preservation, sound insulation and light weight, the hollow board also has more performances according to difference of used polymers such as hydrophilic performance, fire resistance, antibacterial performance and anti-electrostatic performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a core board and its manufacturing method and application. Background technique [0002] The hollow core boards in the prior art mainly include: one is the polymer foamed hollow core board, the main defect of which is poor mechanical performance; the other is the honeycomb hollow core board, the main defects of which are poor water resistance and poor mechanical performance , is not practical. And the two kinds of hollow core panels generally only have basic properties such as heat insulation, heat preservation, sound insulation, and light weight. Contents of the invention [0003] The object of the present invention is to provide a core board and its preparation method and application to address the defects of the prior art. The method is simple and reasonable. In addition to basic properties such as heat insulation, heat preservation, sound insulation, and light we...
