Abstract

The invention discloses a novel foamed wood-plastic template for building and its production process, which belongs to the technical field of building template manufacturing. The invention solves the problem of poor foaming effect of building formwork. The new foamed wood-plastic formwork for construction of the present invention is composed of main material, stabilization system, lubrication system, and foaming system. The production process is to add the raw materials into a hot mixing pot, mix and heat them, and then send them to the main machine for plasticization and foaming after cooling. Open-type water-cooled skinning is carried out on the product through the water channel of the die lip, and then the extruded material is shaped and cooled by adjusting the temperature of the shaping table and the chiller, and the shaped product is cut vertically and horizontally under the traction of the tractor to obtain a standard plate A new type of foamed wood-plastic formwork for construction. The invention is mainly used in the production and manufacture of building templates.

Description

technical field [0001] The invention belongs to the technical field of building formwork manufacturing, and in particular relates to a novel foamed wood-plastic formwork for construction and a production process thereof. Background technique [0002] Plastic, steel, wood, and cement are collectively referred to as the four major building materials. The production and application energy consumption of architectural plastic products is far lower than other materials. Plastic formwork is an energy-saving and environmentally friendly product. An important measure to replace steel. The promotion and application of plastic formwork has broad development prospects, and the use of plastic formwork should be the inevitable development direction of the industry. [0003] In recent years, as the country vigorously advocates the development of energy-saving and low-consumption products, as well as the development of my country's plastics industry and the performance improvement of pla...
