Description
Technical field
The invention belongs to fiber and twine motor body heat insulating construction making field, be specifically related to the manual pasting preparation method that a kind of fiber twines the motor body heat insulation layer.
Technical background
Fiber twines the motor body heat insulation layer mainly to be made up of forward and backward head insulation and manual pasting heat insulation layer three parts, and the manual pasting heat insulation layer is the important component part of heat insulating construction.Heat insulation layer in the past adopts nitrile rubber more, and acrylonitrile-butadiene rubber has Shao Er hardness low (being about 60), yielding characteristics, so the manual pasting processing performance of material is good.Acrylonitrile-butadiene rubber self-adhesion, mutual viscosity can be good, and the adhesive kind of in the paster process, using is easy to select.But because the about 1.3g/cm of density of acrylonitrile-butadiene rubber
3, the oxy-acetylene linear ablative rate is about 0.2mm/s, and scour resistance is poor, and thermal conductivity factor is high, in addition, because the agent of the resistance that acrylonitrile-butadiene rubber uses burning is asbestos, not only be prone to cancer, and because the asbestos deposit deposit reduces, buying is also difficult day by day.Therefore, along with the development of solid propellant rocket technology, its limitation manifests day by day.
Ethylene propylene diene rubber density is minimum in all rubber, does not have two keys in the main chain, and degree of unsaturation is low, low polarity, and thermal conductivity is low, and is high temperature resistant, ageing-resistant, so the EPDM heat insulation layer has low-density, ageing-resistant, anti-advantage of moving.Cooperate suitable enhancing system and efficient antiscour system; Can make the EPDM heat insulation layer have low ablating rate, scour resistance is good, corrosion resistance is strong advantage again, satisfy the requirement of NEPE high-energy propellant, azide propellant, punching engine afterburning chamber, other high-energy solid rocket engine comprehensively.
But compare the acrylonitrile-butadiene rubber heat-insulating material, the Shao Er hardness of EPDM higher (being about 70), owing to be non-polar material, self-adhesion, mutual viscosity can be relatively poor.This also directly causes the manual pasting processing performance of EPDM heat-insulating material far short of what is expected than acrylonitrile-butadiene rubber.Therefore, the manual pasting technology of EPDM heat-insulating material awaits further research, also will directly influence the key point of motor body heat insulating construction fabricating quality.
