Embodiment 1

[0036] Such as Figure 1-Figure 5 As shown, the present invention provides a straw foamed decorative board, which includes two surface boards 1 arranged on the upper and lower sides and a foamed sandwich layer 2 located between the surface boards 1. The foamed sandwich layer 2 Straw segments with a length of 2-6mm are uniformly mixed. A reinforcing frame is also provided between the surface plates 1, and the foamed sandwich layer 2 fills the gap portion of the reinforcing frame. The reinforcing frame includes two layers of grid plates 3 respectively laid on the inner sides of the two layers of the surface panels 1 and a supporting plate connected to the grid plates 3. The inner side of the grid plate 3 is provided with a number of mounting grooves 16 with a trapezoidal cross section. The supporting plate is a corrugated plate 4 with triangular grooves. The top of the corrugated plate 4 is ground and flat with the mounting groove 16 With the matching trapezoidal structure, the...

Embodiment 2

[0056] The basic structure and manufacturing process of the decorative board in this embodiment are the same as those in the first embodiment. The difference lies in that: before the surface board 1 is manufactured, a model including the surface board 1, the side sealing board 14 and the side connecting board 5 is scaled down and manufactured. The surface plate 1 is a flat plate, and the side part of the corrugated plate 4 adjacent to the side connecting plate 5 is fixed in the model, and the side connecting plate 5 is slidably installed in the model. Mark the initial position of the side connecting plate 5, and inject the mixed foaming material into the cavity between the side part of the corrugated board 4 and the side connecting plate 5 according to the ratio, and conduct a foaming test. After the foaming is completed, measure the foamed side The moving distance l of the connecting plate 5 is calculated in proportion to the moving distance L of the side connecting plate 5 in ...

Embodiment 3

[0058] The basic structure and manufacturing process of the decorative board in this embodiment are the same as those in Embodiment 1, and the difference lies in the structure of the grid board 3. The grid on the grid plate 3 is in a rhombus shape, the grid ribs 17 forming the grid intersect with the ribs 6 of the corrugated plate 4 obliquely, and the installation groove 16 is provided at the intersection between the grids or the grid plate 3 on the side. The structural grid plate 3 can decompose the longitudinal force under the action of the longitudinal force of the corrugated plate 4, and the structural strength is higher than that in the first embodiment.

Abstract

The invention discloses a decorative sheet foamed by straw and a manufacturing technology of the decorative sheet. The decorative sheet comprises two layers of surface sheets arranged at the upper andlower sides and a foaming sandwich layer, straw sections of which the length is 2-6 mm are uniformly mixed in the foaming sandwich layer, a reinforcing framework is further arranged between the surface sheets, and the foaming sandwich layer fills a gap part of the reinforcing framework; the reinforcing framework comprises two layers of grid sheets laid on the inner sides of the two surface sheetsrespectively and a supporting sheet connected with the grid sheets, several mounting grooves of which the cross sections are trapezoidal are formed in the inner sides of the grid sheets, the supporting sheet is a corrugated sheet of which a groove channel is triangular, the top of the convex ridge of the corrugated sheet is ground into a trapezoidal structure matched with the mounting grooves, and the sides of the grid sheets are fixedly connected with a side sealing sheet of the side face of the decorative sheet. According to the decorative sheet, the strength of the decorative sheet can beeffectively improved, particularly, the strength of impact to the surface sheets is greatly improved, and only less weight is added to the decorative sheet at the same time.

Description

Technical field [0001] The invention relates to the field of building decoration, in particular to a decorative board foamed with straws and a manufacturing process thereof. Background technique [0002] The rapid economic growth in China has promoted the rise and development of high-rise buildings and large-scale industrial buildings. At the same time, the requirements for various decorative panels in home decoration are also increasing. As decorative materials, decorative panels need to be lightweight, reliable, and resistant to damage and installation. Requirements for firmness, heat insulation, and fire prevention. At present, considering cost, transportation, and reducing load-bearing requirements, many decorative panels use foamed materials with a sandwich core inside. The material of the surface board outside the decorative board is generally high in strength, wear-resistant and not easy to damage, but because the thickness of the surface board is thin, and the foamed san...
