Abstract

The invention belongs to the technical field of high molecular materials, and relates to a composite polyolefin material, a preparation method and a use of the composite polyolefin material. The material comprises 9 parts of an outer layer flame-retardant polyolefin material and 1-4 parts of an inner layer reinforced polyolefin layer, wherein the outer layer flame-retardant polyolefin material is prepared from the following components in parts by weight: 50-80 parts of polyolefin 1, 0-30 parts of a filler 1, 16-35 parts of a fire retardant, 0-9 parts of a flame retardant synergist, 0.1-0.4 part of an antioxidant 1 and 0.1-0.4 part of a lubricating agent 1; and the inner layer reinforced polyolefin layer is prepared from the following components in parts by weight: 50-80 parts of polyolefin 2, 0-45 parts of a glass fiber, 0-30 parts of the filler 2, 0-5 parts of a graft, 0.1-0.4 part of an antioxidant 2 and 0.1-0.4 part of a lubricating agent 2. The material has the advantages of being low in cost, light in weight, good in toughness balance, changeable in size and fireproofing, and being capable of being used for a plurality of times.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a composite polyolefin material and its preparation method and application. Background technique [0002] With the development of the construction industry, construction formwork plays an increasingly important role in it. At present, steel formwork, wood formwork and plastic formwork are widely used. Although the steel formwork has a solid structure and can be used repeatedly, it has the disadvantages of heavy weight, poor corrosion resistance, and difficult demoulding; the wooden formwork can be cut arbitrarily in structure, but it is easy to deform after being exposed to moisture, and the number of repeated uses is small and easy. Burning disadvantages. The plastic formwork is favored by the construction industry due to its light weight, corrosion resistance, and water resistance, but it has not been widely used at present. The reason is that in addition to the insuf...
