Description
Technical field
The present invention relates to construction formwork, particularly relate to the processing method of renewable waste plastics glass construction formwork.
Background technology
In the constructions such as house building, bridge, tunnel construction and fragment of brick production, often use pouring concrete technique, concrete placement needs template.Conventional template comprises plank and steel plate, because plank resource scarcity, steel plate is too heavy again, now use gradually synthetic construction formwork instead, described synthetic construction formwork is wherein commonly used a wood plastic building mould, wood plastic building mould is comprised of regenerated particle such as waste plastics PP, ABS, PVC, PE, and the inside is mixed with wood powder or plant bar powder is that inserts produces (black), and its shortcoming is: be heated under the sun and can be out of shape; Subzero nail one nail meeting cracking; When dropping, the high-altitude easily breaks; Can not construct winter; Another kind is the stone flour plastic building template.The stone flour plastic building template is comprised of regenerated particle such as waste plastics PP, ABS, PVC, PE, and the inside filler is stone flour, and the shortcoming of this plate exists temperature distortion under the sun equally; Subzero nail one nail can ftracture; The high-altitude is dropped easily and is broken; Can not construct winter, and also having maximum drawback is that heat stability is bad, and wave-like appears in excess Temperature, and the number of turnover is few.And it is few that above-mentioned two kinds of synthetic construction formworks also exist specification, and it is inconvenient to piece together mould, and loss is large, and the easily sticking concrete in surface needs the brush release agent, demoulding trouble; Meet the water template and stratification can occur.Can only use the fritter assembly unit, time-consuming taking a lot of work; Useless template is without value, and is not recyclable.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art existence, provide a kind of with recycled plastic, be primary raw material in conjunction with glass fiber, the template of moulding reaches minus 20 degrees also can construct, and the high-altitude is dropped and do not broken, and nail and do not ftracture winter, temperature distortion is little under the sun, the number of turnover is up to more than 50 times, and stripping result is good, and useless plate 100% reclaims the processing method of the renewable waste plastics glass construction formwork of environmental protection and energy saving.
The technical scheme of the processing method of renewable waste plastics glass construction formwork of the present invention is: it is characterized in that:
