Description
Technical field
The invention belongs to insulation material technical field, and in particular to a kind of phenolic resin warming plate and preparation method thereof.
Background technology
Phenolic-aldehyde heat-insulation board and hard polyurethane foam belong to organic thermosetting thermal insulation material together, especially building energy saving rate in recent years
Gradually step up, it is increasing using insulation material technical performance more and more higher, market demand.In Application in Building insulation material
In, physical technique performance height is not only required and it is necessary to reach fire protecting performance.The foam and gather that phenol-formaldehyde resin modified produces
Though urethane hard bubble belongs to relatively good insulation material, excellent, the shortcoming that two class insulation materials are had nothing in common with each other, without fine comprehensive
Technical performance.The hard polyurethane foam of polyurethane resin synthesis, there is lightweight, high-strength, thermal conductivity factor is low, good toughness and easy for construction
The features such as, but fire protecting performance only up to reach B1 levels fire protecting performance, oxygen index (OI) only up to reach 30%.
The phenolic-aldehyde heat-insulation board of phenolic resin production, possesses the main principal advantages of Polyurethane Thermal Insulation Building Materials, but fire line
It can be protruded than hard polyurethane foam, fire resisting combustion penetrates, high temperature resistant, low cigarette, and oxygen index (OI) is up to 50%, but phenolic-aldehyde heat-insulation board and polyurethane
Hard bubble compares, and is that fragility is big, acid big the shortcomings that phenolic-aldehyde heat-insulation board maximum.Because the fragility of phenolic-aldehyde heat-insulation board is big, phenolic aldehyde heat preserving
There is the problems such as dry linting, elasticity is low, compressive strength is low, and thermal conductivity factor is not up to standard in plate, intrinsic excellent fire protecting performance does not have when in use
It can very well be utilized, therefore, influence the extension of the products application technology, while many inconvenience are brought to transport, construction.Especially
Pull strength is low, is not easy to meet relevant criterion requirement.Due to acid big so that phenolic-aldehyde heat-insulation board connects with metal, cement-based material
Touch and have certain corrosivity.
On July 4th, 2012, Chinese invention patent application publication No. CN102533015A, disclosed a kind of external wall outer insulation phenol
The preparation method of aldehyde cystosepiment fire protection flame retarding interfacial agents, it is the poly- phosphorus using vinyl acetate-ethylene copolymerization emulsions as base-material
Sour ammonium is dehydration catalyst, pentaerythrite is carbon forming agent and melamine is the flame-retardant system of foaming agent, and adds other auxiliary agents
It is formulated.The technical scheme is due to being base-material using vinyl acetate-ethylene copolymerization emulsions of aqua type, although in normal temperature
The toughness of insulation phenol formaldehyde foam plate surface can be increased；But the heat decomposition temperature of vinyl acetate-ethylene copolymerization emulsions is relatively low,
About 230 DEG C or so；Run into that high temp fire bakes its viscosity and toughness rapidly disappears, directly contribute coming off for coating material.Therefore, should
Fire protection flame retarding interfacial agents using effect is bad.
The content of the invention
The present invention proposes a kind of phenolic resin warming plate, and the warming plate can avoid scaling-off problem, and with intensity it is high,
