Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, specifically to a heat-insulating molded polystyrene foam board. Background Technology

[0002] Molded polystyrene foam (EPS), commonly known as polystyrene board, is a type of polystyrene plastic sheet with a closed-cell structure, made by pre-expanding expandable polystyrene beads and then molding them in a mold. Its service temperature does not exceed 75℃. It is classified into six categories according to density (kg / m³): Category I ≥15~<20, Category II ≥20~<30, Category III ≥30~<40, Category IV ≥40~<50, Category V ≥50~<60, and Category VI ≥60. It is also classified into two types according to combustion performance: ordinary and flame-retardant. Polystyrene accounts for only about 2% of the material, with the remainder being air. The still air within the honeycomb structure is a poor conductor of heat, thus giving this material excellent thermal insulation properties. Combined with its unique resistance to vapor permeation, high compressive strength, convenient construction and installation, and long service life, it is an important energy-saving thermal insulation material for buildings and is widely used in construction and packaging engineering.

[0003] The invention patent with publication number CN104744843B discloses a graphite polystyrene foam extruded board for thermal insulation. The raw materials, by mass fraction, include: PS polystyrene: 70-80 parts; expanded graphite: 5-13 parts; talc: 1-5 parts; flame retardant: 6-10 parts; carbon black: 0.2-1.5 parts; and CO2 foaming agent: 3-4 parts. The preparation method of this extruded board is as follows: raw materials are stored independently according to their components; automatic control system feeds and mixes the materials; high-temperature first-stage plasticization is performed through a 15m long screw with an average temperature above 180℃; second-stage mixing is performed through a 10m high-temperature screw at 210℃; high-pressure injection of CO2 foaming agent into a mold for foaming; extrusion molding on a platform; initial cooling and forming of the graphite extruded board; edge and corner cutting; secondary processing (roughening, grooving, embossing); transverse cutting; secondary cooling; packaging and warehousing. The extruded polystyrene board of this invention is a black board material, which has the characteristics of good fire resistance, strong heat insulation, lower cost for the same effect, convenient construction, and good system integrity.

[0004] Existing graphite polystyrene foam extruded boards for thermal insulation have low structural strength during use. When subjected to external pressure, the extruded boards are prone to bending and deformation, and large bending can lead to breakage. To solve the above problems, this application proposes a thermal insulation molded polystyrene foam board. Utility Model Content

[0028] The outer wall surface of the plate 1 is provided with a protective frame 5 for protection, and the protective frame 5 is made of metal.

[0029] A transverse insertion hole 7 is provided through the side wall of the plate 1, and a vertical insertion hole 8 is provided through the top of the plate 1. A transverse support rod 9 for transverse support of the plate 1 is inserted into the inner cavity of the transverse insertion hole 7, and a vertical support rod 10 for vertical support of the plate 1 is inserted into the inner cavity of the vertical insertion hole 8.

[0030] It should be noted that flame-retardant boards 4 are glued to both sides of the board 1 with adhesive layer 3. The flame-retardant boards 4 can improve the flame retardancy of the board 1 during use and enhance its safety. The flame-retardant boards 4 are fixed in the mounting groove 2, so that the surface of the flame-retardant boards 4 is flush with the surface of the board 1 to ensure the aesthetics of the board 1 surface. Vertical insertion holes 8 and horizontal insertion holes 7 are respectively opened on the top and sides of the side wall of the board 1, and the vertical insertion holes 8 and horizontal insertion holes 7 are staggered. Vertical support rods 10 and horizontal support rods 9 are respectively inserted into the inner cavity of the vertical insertion holes 8 and horizontal insertion holes 7. The horizontal support rods 9 and vertical support rods 10 provide support in the inner cavity of the board 1, which can improve the structural strength of the board 1 and enhance its flexural resistance during use.

[0031] In this embodiment, as Figure 2 As shown, the inner wall of the protective frame 5 is provided with a fixing slot 12, and the inner wall of the protective frame 5 is engaged with the edge of the outer wall of the plate 1 through the fixing slot 12.
