Silicon-phosphorus hybrid flame retardant, preparation method thereof and silicon-phosphorus hybrid emulsion

The invention provides a silicon-phosphorus hybrid flame retardant which has a structure shown as the formula I. The silicon-phosphorus hybrid flame retardant provided by the invention is a reactive flame retardant; the lateral group of the flame retardant contains a phenyl group, so that the free volume between molecules is reduced, the space baffle is increased, and a flame retardance system has higher glass-transition temperature, therefore, the thermal stability of a base material is improved favorably. Silicon-phosphorus hybrid emulsion with the silicon-phosphorus hybrid flame retardant with the structure shown as the formula I as the main ingredient is suitable for flame-retardant finishing of wool fabric, the finished wool fabric is good in the thermal stability and the flame-retardant effect and is flame-retardant and washable, and the mechanical property and the ultraviolet protection property of the wool fabric are also improved to a certain degree.

PHOSPHORUS-ATOM-CONTAINING OLIGOMERS, PROCESS FOR PRODUCING SAME, CURABLE RESIN COMPOSITION, CURED PRODUCT THEREOF, AND PRINTED WIRING BOARD

[Object] A phosphorus-containing oligomer that has high solubility in an organic solvent and exhibits high flame retardancy and heat resistance in the form of a cured product thereof is provided. The phosphorus-containing oligomer is represented by structural formula (1) below (in the formula, R1 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a phenyl group; n is the number of repeating units and an integer of 1 or more; X is a structural unit represented by structural formula (x1) or (x2) below; is a hydrogen atom, a hydroxyl group, or a structural unit represented by the structural formula (x1) or (x2); and, in the structural formula (x1) or (x2), R2, R3, R4, and R5 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a phenyl groups or an aralkyl group), wherein the content of components whose n is 2 or more in the structural formula (1) is in the range of 5% to 90% in terms of peak area in GPC measurement.
