9. a kind of preparation method of heat-isolating flame retardant material according to any one of claim 1-8, it is characterised in that including
Following steps：
S1：The phenolic resin of corresponding parts by weight, terpene resin and esterified rosin resin are added sequentially in pulverizer carry out powder
It is broken, mixed with resin powder is produced, the temperature with temperature regulating device and the reactor of agitating device is risen into 80~100 DEG C, question response
After reaching, mixed with resin powder is put into above-mentioned reactor, and mixed with 1000~1300r/min rotating speed, waits to set
Fat mixed powder produces resin mixture liquor after all melting；
S2：The temperature of reactor is kept, and it is sub- that the polyamides of corresponding parts by weight is added in the resin mixture liquor prepared into S1 steps
Amine, alkoxy to methylthiophenoxy phosphoramidate, ultra-violet absorber, antioxidant, light stabilizer and ORGANIC SOLVENT MIXTURES, after
10~30min of continuous stirring, it is raw material mixed liquor A that question response temperature, which is down to room temperature,；
S3：Rock wool, asbestos, resurrection glass fibre, composite nanometer particle are added in the raw material mixed liquor A prepared into S2 steps
And polyurethane powder, and reactor is transferred to 30~60min of ultrasound in Ultrasound Instrument, produce heat-isolating flame retardant material finished product.
10. the preparation method of a kind of heat-isolating flame retardant material according to claim 9, it is characterised in that in the S1 steps
The granularity of mixed with resin powder is below 20 mesh, to be obtained by the way of mesh screen, do not meet the mixed with resin powder needs of granularity requirements
Put into pulverizer and be ground again, until the granularity of all raw materials meets the requirements.
