Embodiment 1
[0033] Example 1, a high-density fiberboard and oriented strand board composite structure wallboard, including a composite structure body with a thickness of 2mm, the composite structure body is composed of fiber material, shaving material and adhesive, the composite structure body includes fiber part 1, shavings part 2 and the transition part 3 arranged between the fiber part 1 and the shaving part 2. Fiber part 1 is composed of fiber material and adhesive, with an average density of 1.2g / cm 3 , the thickness is 0.5mm; the shaving part 2 is composed of shaving material and adhesive, with an average density of 0.8g / cm 3 ; The thickness of the shavings is 0.5mm. The transition part 3 is composed of fiber material, shaving material and adhesive, and the mass ratio of the shaving material to the fiber material gradually increases from bottom to top in the thickness direction of the transition part 3 . The transition part 3 includes a first transition part 31 whose mass proporti...
Embodiment 2
[0034] Embodiment 2, the difference between embodiment 2 and embodiment 1 is that the thickness of the main body of the composite structure is 8mm. Of course, the thickness of the main body of the composite structure is only to meet the needs of wallboard applications, so within the range of 2mm-8mm, it can be used according to Need to be sorted; the average density of the fiber part 1 is 0.9g / cm 3 , the thickness is 3mm; the average density of the shaving part 2 is 0.6g / cm 3 , The thickness of the shavings part 2 is 3mm. The average mass ratio of the shaving material to the average mass ratio of the fiber material in the first transition portion 31 is 3.5:5.5; the average mass ratio of the shaving material to the average mass ratio of the fiber material in the second transition portion 32 is 5.5:3.5.
Embodiment 3
[0035] Example 3, a high-density fiberboard and oriented strand board composite structure wallboard, including a composite structure body with a thickness of 6mm, the composite structure body is composed of fiber materials, shaving materials and adhesives, the composite structure body includes fiber part 1, shaving part 2 and the transition part 3 arranged between the fiber part 1 and the shaving part 2. Fiber part 1 is composed of fiber material and adhesive, with an average density of 1.0g / cm 3 , with a thickness of 1mm; the shaving part 2 is composed of shaving material and adhesive, with an average density of 0.7g / cm 3; The thickness of the shavings part 2 is 2mm. The transition part 3 is composed of fiber material, shaving material and adhesive, and the mass ratio of the shaving material to the fiber material gradually increases from bottom to top in the thickness direction of the transition part. The transition part 3 includes a first transition part 31 whose mass prop...
