Abstract

The invention relates to an inflaming retarding reinforcing polyolefin material and a preparation method thereof. The inflaming retarding reinforcing polyolefin material comprises the following components by weight: 30 to 80 parts of polyolefin, 0 part to 10 parts of flexibilizer, 0 part to 45 parts of glass fiber, 0 part to 30 parts of filler, 2 to 30 parts of fire retardant, 0 part to 10 parts of graft, 0.1 to 0.4 part of antioxygen and 0.1 to 0.4 part of lubricant. The inflaming retarding reinforcing polyolefin material has good mechanical performance and processing performance, can achieve V-0 grade inflaming retarding, has a fireproof function and is suitable for extruding molding. The inflaming retarding reinforcing polyolefin material can be continuously extruded through an extruder to form boards for building external wall scaffolds and has the advantages of being low in cost, light in weight, good in rigidity balance, large in recycle times, variable in size, fireproof and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyolefin material and a preparation method thereof. Background technique [0002] In addition to the main role of building formwork in the construction process, exterior wall scaffolding is also essential, and the supporting systems of the two are also different. Exterior wall scaffolding is mainly used to build templates for construction workers, tie bolts, build reinforced slab walls and column steel structures, and walk on them or temporarily place construction tools when removing formwork. The exterior wall scaffolding is mainly divided into a steel pipe support system and a platform for workers to stand and store tools. At present, bamboo fences, wooden templates, or temporarily unused square logs on the construction site can be used as platforms for workers to stand and store tools; among them, bamboo fences are used the most, and their main disadvantage is tha...
