Description

A kind of frie retardant coating and preparation method thereof

Technical field

The invention belongs to building material field, particularly a kind of frie retardant coating and preparation method thereof.

Background technology

Frie retardant coating can reduce by the rapid spread of the combustibility of painting material surface, retardance fire, in order to improve a kind of speciality coating that is coated with material fire endurance.

The fire prevention principle of frie retardant coating can roughly be divided into following: (1) frie retardant coating itself has flame retardancy or uninflammability, and protected base material is not directly contacted with air, postpones the speed that object catches fire and reduces burning; (2) frie retardant coating is except itself having flame retardancy or uninflammability, and it also has lower thermal conductivity, can postpone the transmission of flame temperature to protected base material; (3) frie retardant coating decomposes goes out not fire rare gas element, waters down the inflammable gas that protected object decomposes goes out, and makes it nonflammable or combustionvelocity and slows down; (4) nitrogenous frie retardant coating decomposes goes out the group such as NO, NH3, with organic radical chemical combination, interrupts chain reaction, reduces temperature; (5) expanding fire-proof paint expanded by heating foaming, forms carbonaceous insulated foam coating and seals protected object, postpones the transmission of heat and base material, stops object ignition or Yin Wendu rising and the strength degradation that causes.

Summary of the invention

For above-mentioned demand, the object of this invention is to provide a kind of frie retardant coating and preparation method thereof, the frie retardant coating making has good fire resistance, and provides a kind of with low cost, excellent performance, the frie retardant coating of complete function.

Object of the present invention can be achieved through the following technical solutions:

Speed lapping, to fineness 15-20 μ m, obtains mill base;

A kind of frie retardant coating, made by the component that comprises following weight part:

The weight ratio of described kaolin and Muscovitum is 1:1.

Described whisker is aluminium nitride whisker.

A preparation method for frie retardant coating, the method comprises the following steps:

(1) by ammonium polyphosphate 40-55 part, kaolin 12-20 part, Muscovitum 12-20 part, uncle's 16 carbon mercaptan 8-12 parts, urea 5-10 part, phenyl-phosphate 2-glycidyl ester 5-10 part, whisker 5-8 part and benzoyl peroxide N-BUTYL ACETATE 3-6 part, at 60-65 DEG C, stir 2-5 hour;

(2) product of step (1) is placed in to nitrogen atmosphere, under airtight pressurized conditions, stirs 30-50 minute at 40-50 DEG C, obtain frie retardant coating.

The pressure of described airtight pressurization is 2-5MPa.

Beneficial effect: frie retardant coating of the present invention itself has flame retardancy or uninflammability; protected base material is not directly contacted with air; postpone the speed that object catches fire and reduces burning; by each component adding by a certain percentage; make the frie retardant coating making have good performance, can evenly apply, and product decomposes of the present invention goes out not fire rare gas element; can dilute the content of inflammable gas, make it nonflammable or combustionvelocity and slow down.As nitrogenous component decomposes goes out the group such as NO, NH3, with organic radical chemical combination, interrupt chain reaction, reduce temperature.
