Novel inorganic environment-friendly flame retardant for flame-retardant paper

Abstract

The invention discloses a novel inorganic environment-friendly flame retardant for flame-retardant paper, and particularly relates to the field of inorganic flame retardants, which is prepared from the following raw materials in parts by weight: 19 to 25 parts of ammonium polyphosphate, 0.8 to 1.5 parts of magnesium hydroxide, 0.6 to 0.9 part of magnesium oxide, 3.75 to 5.75 parts of B-type flame retardant and 0.8 to 1.3 parts of guanidine phosphate. The B-type flame retardant is any one of a polypropylene flame retardant, an inorganic flame retardant and a brominated flame retardant. According to the invention, magnesium hydroxide, magnesium oxide and a phosphorus-containing compound are used as main flame retardants, and bound water released when magnesium hydroxide is heated and decomposed is mixed into air, so that the concentration of combustible gas in the air is changed, and related supplementation is provided for the inorganic flame retardant market; the flame-retardant paper has the characteristics of high flame-retardant efficiency, no halogen, environment friendliness, low smoke, low toxicity and the like, has the capability of greatly improving the insulating strength of the flame-retardant paper by adding the components of ammonium polyphosphate, magnesium oxide and guanidine phosphate, has higher production value, use value and application prospect, and reduces the cost of the flame retardant.

Description

technical field [0001] The present invention relates to the technical field of inorganic flame retardants, and more particularly, the present invention relates to a novel environment-friendly inorganic flame retardant used for flame retardant paper. Background technique [0002] For more than 60 years since the early 1950s, especially for about 30 years since the early 1980s, flame retardants (FR) and flame retardant polymer materials have played an important role in reducing the loss of life and property caused by fire . At present, the total amount of FR in the world ranks second only to plasticizers among various plastic additives. The development and development of flame retardants in my country will have better prospects. The fuel industry is developing in the direction of environmental protection, low toxicity, high efficiency and multi-functionality. [0003] The variety and consumption of domestic flame retardants are still dominated by organic flame retardants, and...

Problems solved by technology

Although the most commonly used halogenated flame retardants in flame retardants have unparalleled efficiency in other flame retardant series, their harm to the environment and people cannot be ignored.
