Problems solved by technology

Due to the poor affinity between polar inorganic aluminum hydroxide and the polymer matrix, high filling content will lead to a significant decrease in the mechanical properties of the material, which has become the main obstacle restricting the wide application of polymer materials in this type of flame retardants.
Coupling agents widely used in the market to increase the affinity between polymers and inorganic fillers, such as silane coupling agents, titanate coupling agents, aluminate coupling agents, etc., are added to aluminum hydroxide filled high None of the molecular systems can play a significant role in modification and enhancement
After the addition of these coupling agents, the processing fluidity is still very poor, and the mechanical properties of the material have not been significantly improved.
At present, there are many studies on ultra-fine and nano-sized aluminum hydroxide, but there are few studies on how to improve the performance of the system by adding certain reagents

Abstract

The invention discloses the application of a polyoctodecyl acrylate in the preparation of aluminium hydroxide flame-retardant polypropylene material. Combined polyoctodecyl acrylate is first prepared by adopting the suspension polymerization technique, the combined polyoctodecyl acrylate is mixed with aluminium hydroxide in a high-speed mixer, the mixture is then mixed with polypropylene, the obtained mixture of the polyoctodecyl acrylate, the aluminium hydroxide and the polypropylene is plasticized, cut into granules and dried, and finally the obtained granules are put into an injection machine and shaped, so that the aluminium hydroxide modified flame-retardant polypropylene material is obtained. The aluminium hydroxide-filled high-molecular material has high mechanical impact strength and processing fluidity, and thereby the flame-retardant property of the aluminium hydroxide flame-retardant polypropylene material is improved.

Description

technical field [0001] The invention relates to a new application of polyoctearyl acrylate, in particular to the application of polyoctearyl acrylate in the preparation of aluminum hydroxide flame-retardant polypropylene materials, and belongs to the technical field of modification of polymer composite materials. Background technique [0002] Aluminum hydroxide is recognized as the most environmentally friendly flame retardant. The flame retardant mechanism of aluminum hydroxide is that it decomposes into alumina when heated and releases a large amount of water vapor. It also has the function of eliminating smoke and does not produce secondary pollution. However, as a flame retardant for polymer materials, aluminum hydroxide has the effect of significantly improving the flame retardancy of polymer materials at a higher filling amount. Due to the poor affinity between polar inorganic aluminum hydroxide and the polymer matrix, high filling content will lead to a significant d...
