Embodiment 1~6
[0026] The invention is a high-strength and high-toughness plastic building template, which is composed of a plastic plate and at least one layer of glass fiber grid cloth embedded in the plastic plate. Among them, the composition of the plastic sheet includes plastic, rubber and additives, and the additives include adhesives, compatibilizers, plasticizers, lubricants and coupling agents. See Table 1 for the compositions and specific weight ratios of the plastic plates of Examples 1 to 6.
Embodiment 1
[0028] In Example 1, the number of layers of glass fiber grid cloth embedded in the plastic plate is one layer, and the glass fiber grid is parallel to the surface of the plastic plate. Each square meter of glass fiber mesh cloth contains 280g of glass fiber, and the glass fiber mesh cloth is located at a depth of 0.2~8mm from one side of the plastic building formwork.
Embodiment 2
[0029] In Example 2, the number of layers of glass fiber grid cloth embedded in the plastic plate is two, and the glass fiber grid is parallel to the surface of the plastic plate. And each square meter of upper and lower glass fiber mesh cloth contains 90g of glass fiber, the upper glass fiber mesh cloth is located at a depth of 0.2~8mm from the plastic building formwork, and the lower glass fiber mesh cloth is located at a distance of 0.2~8mm from the plastic building formwork. At the depth of 0.2~8mm on the lower surface.
