Problems solved by technology

[0006] Phenolic foam insulation material has the advantages of light weight, high specific strength, low thermal conductivity, and good flame retardancy. However, phenolic foam material has poor toughness, brittle quality, and easy to drop slag. These shortcomings restrict its application in building energy-saving projects. application in
And other inorganic thermal insulation materials, such as rock wool, glass wool, cement foam board, silicate plate, glass bead fireproof insulation board, because of their own weight, high thermal conductivity, poor hydrophobicity, poor thermal insulation effect and other shortcomings, not suitable for thermal insulation. Applicable to thin plastering system for exterior wall insulation in building energy-saving projects

Embodiment 1

[0039] Example 1 : Take 95 parts by weight of expandable phenolic resin and pour it into the mixer, then add 10 parts by weight of malt paste, 13 parts by weight of perlite, 5 parts by weight of urea-formaldehyde resin, 5 parts by weight of silicone oil, and 5.5 parts by weight of stage A phenolic resin. Add 10 parts by weight of the agent into the mixing tank and stir for 10 to 20 minutes. After stirring evenly, put it into the mold in a drying room at 50°C, dry for 3 hours, cool and demould, and then the thermal insulation and fireproof material of the present invention can be obtained. .

[0040] The resole phenolic resins in this example and subsequent examples are all obtained through the following process: phenol and paraformaldehyde are passed through the first stage at a weight ratio of 4:1 to 4:3, and the temperature is controlled at 75°C to 80°C. ℃ between batch feeding, time control within 2 hours. The temperature of the second stage is controlled at 82°C to 83°C...

Embodiment 2

[0044] Example 2 : Take 100 parts by weight of expandable phenolic resin and pour it into a blender, then add 12 parts by weight of malt paste, 15 parts by weight of perlite, 4 parts by weight of urea-formaldehyde resin, 6 parts by weight of silicone oil, and 7 parts by weight of phenolic resin in the first stage, and solidify Add 10 parts by weight of the agent respectively and stir for 10 minutes. After stirring evenly, put it into a mold in a drying room at 30° C., dry for 3 hours, cool and demould, and then obtain the thermal insulation and fireproof material of the present invention.

Embodiment 3

[0045] Example 3 : Take 105 parts by weight of expandable phenolic resin and pour it into a blender, then add 12 parts by weight of malt paste, 13 parts by weight of perlite, 4 parts by weight of urea-formaldehyde resin, 4 parts by weight of emulsifier, and 6 parts by weight of foaming agent. 8 parts by weight of the agent were added and stirred for 15 minutes, and after being evenly stirred, it was put into a mold in a drying room at 60°C, dried for 3 hours, cooled, and demolded to obtain the thermal insulation and fireproof material of the present invention.

Abstract

The invention discloses a phenolic foam thermal-insulating fire-proof material and a production method thereof. In the invention, the phenolic hard foam thermal-insulating fire-proof material is prepared with a foamable phenolic resin being employed as a main material and with malt paste, perlite, urea resin, an emulsifier, a foaming agent and a curing agent being employed as auxiliary materials. Compared with a thermal-insulating material in the same type, not only are the advantages of light self-weight, high strength, less thermal-conductive coefficient, low smoke density and less calorific value of a conventional phenolic hard foam thermal-insulating fire-proof retained, but also defects of being crisp, poor flexibility and being liable to crumb are overcome. When being fired with fire, only a carbonized layer is formed on the surface of the material and combustion and deformation phenomenon are free. Compared with a common external wall thermal-insulating material EPS / XP / PU in the prior art, the phenolic foam thermal-insulating fire-proof material is low in the smoke density, is fire-retardant and is low in thermal-conductive coefficient. A flame-retardant performance is greatly improved and can achieve an A grade according to GB8624-1997.

Description

technical field [0001] The invention relates to a thermal insulation fireproof material and a production method thereof, in particular to a phenolic foam thermal insulation fireproof material and a production method thereof. Background technique [0002] Since the implementation of building energy-saving measures in our country, the thin plaster insulation system for external wall insulation has been widely used. [0003] However, the combustion performance of the insulation materials EPS board (polystyrene board) and XPS (extruded polystyrene board) in this system can only meet the B1 standard required by GB8624-1997, and a large amount of toxic smoke is produced during flame retardancy, which is seriously restricted The application of thin plastering system for exterior wall insulation in building energy-saving projects. [0004] The expanded perlite flame-retardant and thermal insulation composite material of Wang Wanjin, the inventor of Beijing Chaoran New Building Mate...
