Abstract
The invention discloses a phenolic-resin-base metal hot working protective paint which comprises the following components in parts by weight: 100 parts of thermosetting phenolic resin, 20-150 parts of solvent, 5-12 parts of curing agent and 10-40 parts of intumescent flame retardant. The phenolic resin is a room-curing thermosetting phenolic resin. The phenolic resin matrix has excellent bonding property with the metal material surface, thereby satisfying the billet storage requirements under different technological conditions. The phenolic-resin-base protective paint has the characteristic of fast drying, and the billet can be used immediately after being sprayed. The phenolic resin can not be carbonized or generate molten drops at high temperature, thereby reducing the consumption of the intumescent flame retardant in the formula and lowering the product cost. Meanwhile, the phenolic resin can form a continuous coating to protect the metal surface at lower temperature. The intumescent flame retardant is decomposed to form a compact carbon layer so as to protect the metal surface at high temperature.
Description
Technical field
The invention belongs to paint field, relate to a kind of metal coating, specifically relate to a kind of phenolic resin base
Metal fever processing protective coating and preparation method thereof.
Background technology
Metal material heat processing typically requires and heats in air dielectric and insulation.Along with the rising of temperature, gold
Belong to and oxidation and decarbonization will occur.During burning, it is usually formed oxide skin.Analyze the structure of oxide skin
It is found that its short texture has crackle, and thickness is the thickest, causes metal material to be lost, and mechanical property reduces；
Also want labor intensive, material resources, financial resources for removal oxidation and decarbonization layer simultaneously.
The measure reducing high-temperature oxydation decarburization has vacuum protection heating, salt bath heating, Controlled Atmosphere Protect, part
The heating of outer cladding stainless steel material, quickly heating, coating protection heating etc..Wherein coating protection heating has throwing
The features such as money is less, operational approach is simple, low cost, strong adaptability.
Metal hot-working needs the high temperature of more than 800 DEG C, the most current commonly used resistant to elevated temperatures inorganic non-
Metal material is as the matrix of metal material heat processing protective coating.The protection mechanism of inorganic non-metallic class coating
For: (1) molten film shield type protection mechanism.It is fine and close and firm that this mechanism utilizes coating to be formed in heating process
Glassy mass or glass ceramics shape thing, adhere on the surface of the workpiece, isolation atmosphere and the contact of matrix, reach
Protection purpose.(2) response type protection mechanism.It utilizes boride to add the micro-oxidation of heat fusing and steel surface
Thing generation chemical reaction, forms the molten film of thin plastic state, covers on the surface of iron and steel, isolation atmosphere and matrix
Contact, reaches to protect purpose.(3) oxidation-reduction type protection mechanism.It is mainly characterized by Cucumber in coating,
It is heated to uniform temperature, first reacts with furnace atmosphere, cause the active medium near metallic matrix poor,
Can not react with matrix, play a protective role.The most molten film shield type protection mechanism is considered as heat treatment
The main reason that coating can shield.
But in actual applications, the metal fever processing protective coating of inorganic non-metallic class shows all deficiencies,
Mainly have: the bonding force of (1) Inorganic Non-metallic Materials and metal is low, it is impossible to meet actual production process requirements.
In commercial production, also need to stack arrangement again after billet spraying hot-working protective coating and reach the standard grade.As pilling up time exceedes
24h, the metal fever processing protective coating of inorganic non-metallic class can self falling.In stacking process, between billet
Phase mutual friction and collision, the metal fever that will also result in inorganic non-metallic class processes coming off of protective coating.(2)
At relatively low temperature section, the metal fever processing protective coating protective capability of inorganic non-metallic class is limited.Inorganic
Non-metal kind metal fever processing protective coating protection mechanism be mainly Inorganic Non-metallic Materials 800 DEG C with
On high temperature under melted, form liquid mucosa.Add alkali metal oxide and can reduce the melted temperature of protective coating
Degree is to about 600 DEG C, but alkali metal oxide can cause the high temperature corrosion to metallic matrix.Therefore, at base
Before ingot surface temperature reaches the melt temperature of protective coating, the metal fever processing of particulate inorganic non-metal kind is protected
Protect coating and cannot effectively protect metal surface.
Summary of the invention
The invention aims to for the problem producing oxidation and decarburization in metal hot-working, Yi Jixian
There is the deficiency of inorganic non-metal kind metal fever processing protective coating, it is provided that a kind of phenolic resin Base Metal hot-working is protected
