Novel composite bio-based building template material and system

Abstract

The invention relates to a novel composite bio-based building template material.The novel composite bio-based building template material comprises chemical components including, by weight, 43.63-47.41% of PVC (polyvinyl chloride), 33.06-36.67% of light calcium carbonate, 10.57-11.54% of wood meal, 0.52-0.71% of stearic acid, 0.52-0.61% of PE (polyethylene) wax, 2.18-2.55% of stabilizers, 2.61-2.75% of CPE (chlorinated polyethylene), 0.86-1.09% of ACR and 1.3-1.43% of DOP (dioctyl phthalate).The novel composite bio-based building template material has the advantages of saving of a great quantity of wood, excellent physical and mechanical performances, light weight, high impact strength, high turnover rate, high flatness, convenience and quickness in mounting and demounting, excellent heat insulation performance, good sound absorption effects, avoidance of use of release agents, avoidance of onsite construction wastes, high standard and universality and evident price superiority.

Description

technical field [0001] The invention relates to a base building formwork material and system, in particular to a novel composite bio-based building formwork material and system, which belongs to the technical field of building materials. Background technique [0002] The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce engineering costs. The building formwork structure used in the construction of cast-in-place concrete structures is mainly composed of three parts: panels, support structures and connectors. The panel is the load-bea...

Problems solved by technology

[0003] (1) The traditional building formwork in the market wastes resources and is not environmentally friendly; the turnover rate of traditional building formwork is very low and the surface is not smooth; among them: bamboo and wood formwork are easy to absorb moisture, easy to mildew, easy to moth, not resistant to acid and alkali, easy to crack, Easy to warp, easy to retreat, easy to shrink, low hardness; metal formwork has poor insulation, is not resistant to acid and alkali, and is heavy

[0004] (2) The assembly and disassembly of traditional building formwork is troublesome, labor-intensive and time-consuming

[0005] (3) Metal formwork in traditional building formwork has poor thermal insulation performance (concrete construction in winter is difficult to demould due to freezing), and poor insulation performance

[0006] (4) The cost of traditional building formwork is relatively high, among which: the amortization times of bamboo and wood formwork are very limited and the assembly and disassembly are time-consuming and costly

The one-time investment cost of metal formwork is high, and the capital requirements of the construction unit are high

[0007] The above defects affect the quality of building templates and restrict the development of traditional building templates
