Abstract

The invention discloses a building template material. The building template material is prepared from the following components in parts by weight: 100 parts of fiberglass reinforced diamantine polyamide grafted polyolefin resin, 1 to 3 parts of a toughening agent and 1 to 3 parts of an antioxidant. A preparation method of the material collection tank comprises the following steps: adding all components in a high-speed mixer for uniformly mixing after weighing the components in proportions, feeding the mixed materials into a double-screw extruder through a feeder in accurate metering, carryingout high-speed shearing and mixing by double screws, and carrying out extruding, bracing, air-cooling, sized dicing, drying and packaging by a machine head, thus obtaining the building template material. The building template material disclosed by the invention is higher in strength, higher in toughness, excellent in ultraviolet aging resistance and flame resistance and easy in machining shaping.

Description

technical field [0001] The invention relates to a building material, in particular to a building formwork material and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, all kinds of high-rise buildings have sprung up on the streets of the city, becoming a beautiful landscape of the modern city. In the construction process of these high-rise buildings, various building materials are needed, and the performance of building materials directly affects the quality of building materials engineering. Building formwork is one of these many building materials. It is a temporary support structure. It is made according to the design requirements, so that the concrete structure and components can be formed according to the specified position and geometric size, maintain their correct position, and bear the weight and function of the building formwork. external loads on it. The purpose of fo...
