Abstract

Organic matter accord with fire-retardant pharmaceutical involve first kind have fire-retardant performance of cigarette restraining machine already, it is good with ogranic material compatibility, have fire-retardant pharmaceutical of complex which mends strong function to the organic material its chemistry makes up :[M2+(1-x)M3+x(OH)2]X+An-x / n.y H2O among them for M2+for Mg2+,Ca2+,Mn2+,Fe2+,Co2+,Ni2+,Cu2+Zn2, + when two price metal cation one of; M3+Al3+Fe3+,Cr3+,Co3+when one of three price metal cation; An-the having fire-retardant performance or the inorganic of helping fire-retardant performance or mixing the anion organically for n of attitude that the flat fare, the fetching velue range of n is 0.1<=n<=6; The fetching value range of x is 0.1 C09K 21 / 06 0 5 1 2004 / 5 / 31 1583954 2005 / 2 / 23 1283751 2006 / 11 / 8 2006 / 11 / 8 2006 / 11 / 8 Dongnan Univ. 210096 Lei Lixu shen lian 32200 The Patent Agency of the South-East University No.2 Sipailou, the City of Nanjing, Jiangsu Province 210018

Description

technical field [0001] The invention relates to a kind of flame retardant compounded with organic flame retardants and inorganic flame retardants by chemical methods, especially having smoke suppression and flame retardant properties, good compatibility with organic materials, and reinforcing effect on organic materials composite flame retardants. Background technique [0002] In recent years, the widespread use of synthetic polymer materials has brought us various conveniences and comforts. But because most of them are combustible substances, if the problem of flame retardancy is not considered, the hidden danger of fire will inevitably plague us all the time. For example, many residential fires are said to originate from packaging materials for heat-generating appliances, such as television casings, that have not been flame-retardant treated. For this reason, it is necessary to develop flame retardant technology to make polymer materials into flam...
