Problems solved by technology

At present, the domestic construction industry generally uses glued formwork and bamboo formwork as building formwork, but these two kinds of glued building formwork have a short service life, and the products cannot be recycled and reused after use. Deformation caused by moisture, the use of building formwork in climates such as large temperature changes, drought or rainy seasons will easily cause poor initial viscosity of the slab and affect the quality of the building

Abstract

The invention relates to a method for manufacturing a building template. The method comprises the following steps of: uniformly mixing paraffin, soybean oil, calcium stearate and dibasic lead phosphite in parts by weight, then adding to a mixing machine with calcium hydrogen powder, PVC5 type resin and a 801 building adhesion agent together, stirring, then adding calcium hypochlorite, and continuously stirring to obtain a mixture; placing the mixture into a heating furnace, heating at 40-60 DEG C for 1-1.5 hours, and placing into a granulator for granulation to manufacture building template granules; placing the building template granules into an extruder, carrying out high-temperature extrusion forming at the temperature of 200-280 DEG C and the speed of 1300-1400 turns / minute to obtain the building template. The method disclosed by the invention has the advantages of simple production process, low cost, waterproof property, fireproof property, acid resistant property, alkali resistant property, recycling and reusing.

Description

technical field [0001] The invention relates to a production method of building formwork. Background technique [0002] At present, in the process of building construction and use, the building structure is mainly composed of concrete structure, and the building formwork is an indispensable part of the building structure. Building formwork can shape concrete structures and components according to the specified position and geometric dimensions, maintain their correct positions, and have the ability to enhance the load of the wall. At present, the domestic construction industry generally uses glued formwork and bamboo formwork as building formwork, but these two kinds of glued building formwork have a short service life, and the products cannot be recycled and reused after use. Due to the deformation caused by moisture, the use of building formwork in climates such as large temperature changes, drought or rainy seasons will easily cause poor initial viscosity of the slab and...
