Embodiment 1

[0088] First, with respect to 100 parts by mass of the above-mentioned liquid resole type phenolic resin, add 3 parts by mass of a silicone-based foam stabilizer (trade name "L-5420", manufactured by Japan Unica Co., Ltd.) as a foam stabilizer and 8 parts by mass of n-pentane (manufactured by Eskei Sangyo Co., Ltd.) as a foaming agent were mixed, and the temperature of the mixture was adjusted to 5°C. The total amount of the resulting mixture, and 2 parts by mass of hexamethylenetetramine (average particle diameter 11 μm) as an additive and 13 parts by mass of xylenesulfonic acid as an acid curing agent (trade name "TEIKATOX 110", Teika Co., Ltd. Production) Stirring and mixing with a paddle mixer to prepare a foamable resol-type phenolic resin molding material. Next, pour the molding material into a metal mold frame (length 300mm x width 300mm x height 50mm) covered with glass non-woven fabric, and then immediately place the same glass non-woven fabric to make a sandwich stru...

Embodiment 2

[0090] In embodiment 1, with respect to 100 mass parts of liquid resole type phenolic resins, further add 2 mass parts of calcium carbonate as inorganic filler, and change acid curing agent to 14 mass parts, except that it is the same as embodiment 1 A phenolic resin foam was prepared in the same manner. Table 1 shows the physical properties of this foam.

Embodiment 3

[0092] In Example 1, except having changed the average particle diameter of hexamethylenetetramine into 36 micrometers, it carried out similarly to Example 1, and prepared the phenolic resin foam. Table 1 shows the physical properties of this foam.

Abstract

A foamable resol type phenolic resin molding or forming material comprising a liquid resol type phenolic resin, foaming agent, a foam stabilizer, an acid curing agent and an additive, the additive being a nitrogen-containing bridged cyclic compound having an average particle diameter of 80 µm or less, and a phenolic resin foamed product formed by foaming and curing the above molding or forming material.

Description

technical field [0001] The present invention relates to a foamable resole phenolic resin type phenolic resin molding material, a preparation method thereof and a phenolic resin foam. More specifically, the present invention relates to a phenolic resin foam that can be produced on the basis of favorable foaming and curing properties, especially has improved appearance, has practical strength and brittleness, has high pH, ​​and has good corrosion resistance. Foamable resol type phenolic resin molding material for foam body and preparation method thereof. Background technique [0002] Conventionally, phenolic resin foams have been used in industrial fields such as construction as heat insulating materials because they are excellent in heat insulation properties, flame retardancy, and fire resistance. [0003] However, the phenolic resin foam is usually produced by foaming and curing a foamable phenolic resin molding material containing at least a liquid resol-type phenolic res...
