Problems solved by technology

[0005] At present, most of the hollow boards made of raw materials on the market have a single shape and different performances, especially the flame retardancy is not very good, and it is flammable.
Since the electrostatic dust collection module needs to work under high voltage for a long time, it is easy to break down and spark when the work is abnormal, and then cause a fire. Therefore, it is necessary to develop a flame-retardant hollow board with fireproof effect and good insulation

Abstract

The invention specifically relates to a composition for a flame-retardant hollow board and a preparation method thereof, and the flame-retardant hollow board and application thereof, belonging to thetechnical field of high-molecular flame-retardant materials. The composition for the flame-retardant hollow board is characterized by comprising, by weight, 88-94 parts of polypropylene particles, 5-10 parts of a filling material, 0.8-1.5 parts of a flame retardant, 0.3-1.1 parts of a dispersant and 0.05-0.11 part of an antioxidant. The invention also provides a preparation method for the composition used for the flame-retardant hollow board, and the flame-retardant hollow board and application thereof. The flame-retardant hollow board has good flame retarding effect, good oxidation resistance, good insulation properties and no pollution to environment. At the same time, the flame-retardant hollow board prepared from the composition for the flame-retardant hollow board by using a preparation method for the flame-retardant hollow board can reach the UL94 V2 level without influence on the insulation performance of the hollow board, and can be applied to an electrostatic precipitator.

Description

technical field [0001] The invention relates to the technical field of polymer flame retardant materials, in particular to a composition for a flame retardant hollow board and a preparation method, a flame retardant hollow board and applications thereof. Background technique [0002] The plastic middle board (also called hollow partition board, Wantong board, double wall board, corrugated board) is made of modern chemical HDPE and HDPP materials, which is a light weight (hollow structure), non-toxic, non-polluting, waterproof, shockproof, A new material with anti-aging, corrosion resistance and rich colors. Compared with cardboard structural products, hollow board has the advantages of moisture resistance, corrosion resistance, and lighter weight to replace cardboard. Compared with injection molding products, hollow panels have the advantages of shock resistance, flexible structure design, and no need to open injection molds. Hollow board, as an environmentally friendly pla...
