A building formwork material

Abstract

The invention discloses a novel building template material, which comprises the following components in parts by weight: 50-90 parts of polyolefin, 1-10 parts of toughening agent, 5-45 parts of glass fiber, 1-10 parts of graft, 0.1-0.4 part of antioxidant and 0.1-0.4 part of lubricating agent. The glass fiber reinforced polyolefin material has favorable mechanical property and processability, can be manufactured into a plastic template through carrying out continuous extrusion molding by using an extruder and has multiple advantages of high strength and high tenacity under extremely thin wall thickness, low cost, light weight, good rigidity and tenacity balance, easy demolding, capability of recycling multiple times, changeable size, recyclability and the like. Compared with the template made of other materials, the novel building template material which has the same area as that of the template made of the other materials is thinner, lighter and convenient to transport and construct and has favorable application prospect.

Description

technical field [0001] The invention relates to the field of building construction templates, in particular to a novel building template material. Background technique [0002] The templates used in building construction are generally steel molds, wood molds, bamboo molds, and plastic molds. Although the steel formwork is strong and has many repetitions, it has high cost, heavy weight, narrow format, and many joints. It is inconvenient for construction and transportation, easy to rust, requires anti-corrosion treatment, and high maintenance costs; bamboo and wood formwork are light in weight and wide in format. , There are few seams, but its strength is relatively low, it is not waterproof, it is easy to mildew and rot, the number of repeated uses is small, and it consumes a lot of green resources. In order to solve these problems, there are also plastic formworks, which are light in weight, non-stick to concrete, and can be reused many times, but their disadvantages are po...

Problems solved by technology

Although the steel formwork is strong and has many repetitions, it has high cost, heavy weight, narrow format, and many joints. It is inconvenient for construction and transportation, easy to rust, requires anti-corrosion treatment, and high maintenance costs; bamboo and wood formwork are light in weight and wide in format. , There are few seams, but its strength is relatively low, it is not waterproof, it is easy to mildew and rot, the number of repeated uses is small, and it consumes a lot of green resources

In order to solve these problems, there are also plastic formworks, which are light in weight, non-stick to concrete, and can be reused many times, but their disadvantages are poor rigidity and easy deformation; at the same time, the formwork assembled after direct injection molding also has insufficient toughness , the disadvantage of easy damage when working at heights

Patent CN1242462A discloses a reinforced foamed plastic formwork, which is a step forward in the previous plastic formwork technology, but the use of foaming agent has brought adverse effects on the production environment, and on the formwork obtained by extrusion and shaping, The lower wall is thicker and the specific gravity is larger
