Problems solved by technology

②High production cost and serious environmental pollution
At present, people are increasingly using other synergists of halogenated flame retardants, including iron oxide and zinc compounds, such as zinc borate, zinc oxide, zinc molybdate and zinc phosphate; but the synergistic flame retardant effect of these products is not ideal , due to the limitation of processing stability and environmental protection conditions, it cannot be widely used

Abstract

The invention relates to an environment-friendly low-cost flame-retardant aid which is added into an organic synthetic material and a preparation method thereof. The synergistic flame retardant comprises the following components in percentage by weight: 10 to 15 percent of nanometer silicon dioxide, 70 to 80 percent of magnesium oxide, 3 to 5 percent of alumina, 1 to 2 percent of silane coupling agent, and 1 to 8 percent of pentaerythritol tetrastearate. The preparation method comprises the following steps of: 1, performing coating treatment on the silane coupling agent and the nanometer silicon dioxide by using organosilicon, wherein the treatment time is 2 to 3 hours; and 2, crushing the nanometer silicon dioxide which is subjected to coating treatment and other components, and mixing to form an uniform mixture. The flame-retardant aid can partially substitute antimony oxide in a halogen and antimony flame-retardant system, can ensure that materials have good flame-retardant properties, and reduces the total cost of material products at the same time; and the preparation method is simple.

Description

technical field [0001] The invention relates to a flame retardant additive added to organic synthetic materials and a preparation method thereof. Background technique [0002] The continuous development and innovation of plastic modification technology has driven the development and birth of various additives. The amount of flame retardant is an additive second only to plasticizer in plastic additives. [0003] The ideal flame retardant should be high flame retardant efficiency, small amount of addition, non-toxic, smokeless, friendly to the environment, good thermal stability, easy to process, have little effect on the properties of the flame retardant, no precipitation, use Convenient and cheap. However, there are almost no flame retardants that meet the above requirements at the same time. In reality, the best comprehensive balance benefits can only be achieved under the premise of meeting the basic requirements. [0004] The use of existing flame retardants in the mar...
