Abstract

The invention relates to composites and methods for producing a plastic-steel square timber and a straw foamed plastic square timber. The composite for producing the plastic-steel square timber comprises the components of PVC (polyvinyl chloride), light calcium carbon powder, a PVC stabilizer, a PVC foaming regulator, an AC (azodicarbonamide) foaming agent, a stearic acid, PE (polyethylene) wax, ACR (acrylate), titanium dioxide, calcium stearate and DOP (dioctyl-phthalate). The composite for producing the straw foamed plastic square timber is prepared from straw power in addition to the components of the composite for producing the plastic-steel square timber. The methods for producing the plastic-steel square timber and the straw foamed plastic square timber from the composites comprise the following steps: proportioning materials, blending materials, adding materials, extruding, molding, cooling by water, quickly freezing, dragging and forming. The plastic-steel square timber and the straw foamed plastic square timber can replace the original wooden timber, are made of single materials, are convenient to product and recycle and can be smashed for secondary machining and shaping.

Description

technical field [0001] The invention relates to the technical field of square logs for building construction, in particular to a composition and a production method for producing plastic-steel square logs and straw-foamed plastic-steel square logs. Background technique [0002] Most of the building square logs in the prior art are made of wood. Because the building environment is in the wild, the wind blows and the sun exposes, the service life of the wooden square logs is not long. To solve this problem, some composite square wood substitutes have appeared in recent years. [0003] Such as Chinese utility model patent 200720021900.X, discloses a kind of connecting body that replaces building square wood, and it comprises strip-shaped metal groove, and groove has bottom plate and side wall, and solidifiable filler is arranged in groove. The filler can be a thermoplastic or settable material such as plastic, plaster, sawdust glue, etc. The groove can increase the support st...
