Embodiment

[0019] Take the following raw materials

[0020] Thermoplastic phenolic resin 100 parts

[0021] Hexamethylenetetramine 10 parts

[0022] 15 parts of isocyanate

[0023] Polyalkylene oxide 0.5 parts

[0024] Foam glass 30 parts

[0025] Mix and fully stir to obtain a phenolic foam composition.

[0026] Put the plates or pipes to be composited into the mould, inject the well-mixed phenolic foam composition into the foaming mould, and foam at room temperature for 20 minutes.

[0027] After 20 minutes, open the mold to get the fireproof board or pipe.

[0028] Then carry out post-processing such as deflashing to obtain the finished product.

Abstract

The present invention relates to the production process of modified fireproof foamed phenol aldehyde plate and pipe, and features that the modified fireproof foamed phenol aldehyde plate or pipe consists of compounded foamed phenol aldehyde composition and base plate or pipe. The foamed phenol aldehyde composition consists of phenol aldehyde resin, hexamethine tetramine, isocyanate, polyalkylene oxide, foamed glass and other components. The modified fireproof foamed phenol aldehyde plate and pipe has low thermal conductivity, high strength, light weight, high fireproof effect and other advantages.

Description

technical field [0001] The invention relates to a method for making a fireproof plate pipe. Background technique [0002] At present, there are many types of air-conditioning ventilation and pipe insulation materials known, such as rock wool, glass wool, aluminum silicate, expanded perlite, polyurethane, polystyrene, etc. It plays a key role, but its application in some fields is limited due to complex manufacturing process, non-flame retardant, low strength, high production cost, and environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for making modified phenolic foam fireproof board pipes without pollution, low in manufacturing cost and good in heat preservation effect. [0004] The technical solution that realizes the object of the present invention is as follows: [0005] The manufacturing method of the modified phenolic foam fireproof board and pipe is characterized in that: the modified phenolic fo...
