A kind of forming method of high-precision great surface quality thermal protective coating, it is characterized in that, include the following steps, step 1, makes mold corresponding with required thermal protective coating surface, and the shape and any surface finish in mold face corresponding with thermal protective coating surface meet design requirement, step 2, die surface processing: die surface is cleaned out, and uniformly smears release agent or release wax, room temperature hang 2~3h；Step 3 sprays heat-resistant paint: in mould surface spraying resin base heat-resistant paint, until heat-resistant paint final thickness, forms thermal protective coating；The thermal protective coating that the present invention makes, surface are the stripping surfaces being bonded with mold height, therefore not only dimensional accuracy is high, and it is smooth, with very low coefficient of friction.
Description
Technical field
The present invention is a kind of forming method of high-precision great surface quality thermal protective coating, is related to a kind of molding of thermal protective coating
Method, it is especially a kind of to construct in high-precision, great surface quality and the tree having compared with low-friction coefficient on composite products
Aliphatic radical thermal protective coating forming method.
Background technique
Heat-resistant paint is generally made of base-material, heat-resisting face (filling out) material, auxiliary agent and solvent.Compared to common coating, solar heat protection apply
Material has the characteristics that solid content is high, granularity is big, viscosity is high；Simultaneously to reach enough anti-ablations and thermal protective performance, solar heat protection is applied
Layer thickness requirements are larger, are 3~8 times of general utility functions coating layer thickness.Therefore the control difficulty of thermal protective coating coating quality is larger,
And coating surface is generally rendered as coarse, granular sensation coating complexion.Or needs higher for surface requirements precision and other structures
Combined product is assembled in part contact friction, conventionally sprays out the coating result come and is not able to satisfy practical need generally
It asks.Such as in missile weapon system emission process, launching tube inner wall thermal protective coating bear high pressure, the pneumatic thermal shock of high temperature it is same
When, body is launched by components such as rudders along barrel coating surface friction.Using it is traditional on launching tube inner wall directly
The coating that the process of spraying forms out, surface accuracy and smoothness are not able to satisfy requirement, can not ensure body
Smoothly emitted with precise speed and straightness.
Summary of the invention
The purpose of the present invention is to provide a kind of forming methods of high-precision great surface quality thermal protective coating, solve resin base
Thermal protective coating thickness precision is low, coating complexion is coarse etc. is not able to satisfy the coating spraying surface quality problems of requirement.
A kind of forming method of high-precision great surface quality thermal protective coating, which is characterized in that include the following steps,
Step 1, makes mold corresponding with required thermal protective coating surface, and mold is corresponding with thermal protective coating surface
The shape and any surface finish in face meet design requirement,
Step 2, die surface processing: die surface is cleaned out, and uniformly smears release agent or release wax, room temperature are dried in the air
Set 2~3h；
Step 3 sprays heat-resistant paint: in mould surface spraying resin base heat-resistant paint, until heat-resistant paint final thickness,
Form thermal protective coating；
Step 4, heat-resistant paint curing of coatings: coating is completed to solidify according to curing cycle；
Step 5, formed product: uncured substrate product is fixed on the thermal protective coating of mold, and molding, pressurization make
Uncured substrate product is bonded completely with thermal protective coating；
Step 6 completes the solidification of all material；
Demoulding: step 7 mould machine is deviate from, thermal protective coating is with product and mold separation.
Wherein, uncured substrate product is fixed in step 5 on the thermal protective coating of mold, described fixation refers to paving
Patch or winding.
The present invention and the production method of existing thermal protective coating are all different, and existing thermal protective coating is sprayed on molding product
Heat-resistant paint is applied or adheres to, to form thermal protective coating, the present invention is that thermal protective coating is first made on mold, then will be uncured
Substrate product fits together with thermal protective coating.
The present invention proposes the thermal protective coating forming method of a kind of high dimensional accuracy, great surface quality, especially a kind of high ruler
The resin base thermal protective coating forming method of very little precision, great surface quality, the coating suitable for most of composite products surfaces
Coating.
The thermal protective coating that the present invention makes, surface are the stripping surfaces being bonded with mold height, therefore not only dimensional accuracy
Height, and it is smooth, with very low coefficient of friction.
