The urethane resin main material containing an organic blowing agent and the urethane resin curing agent are sent out separately from the supply pipe of the system quantitatively according to their composition, and after passing through the kneading section, are discharged from a single supply pipe. Some were very simple, such as ALC manufacturing, where the mixture was mixed in one kneading section, poured into a mold, and then cured in water over and over again, a simple batch process. In this way, in the production of conventional foams, a simple method was sufficient, but in the production of the inorganic/organic composite foam shown in the present invention, the reactions are stepwise and intricately intertwined, so Conventional manufacturing techniques such as these were not suitable for the actual situation. As a result of intensive research, the inventors of Zero have completed the present invention.

してしまう。The present inventors have energetically carried out various experiments and research, and have obtained multi-stage results such as measuring the stability time after kneading of the inorganic/organic composite foamable composition referred to in the present invention, measuring the foamable time, and considering the reaction mode. We considered dividing kneading and found that the division described below is most suitable for continuous production. That is, (a) inorganic filler, (d) reaction rate regulator, (e) additive, (r)
Water is kneaded in mixer 1 to obtain paste (A). The pot life of paste (A) varied depending on the type of inorganic filler (a), but it was at least 4 hours. 5 This was stirred and stocked. The paste (A) is supplied in a constant quantity by pump P+2. In a system independent of this (
b) The inorganic blowing agent is directly supplied in a fixed amount to the kneading section 6 in powder form, or the inorganic blowing agent and (f) water are kneaded and dispersed in the mixer 3 and then supplied in a fixed amount to the kneading section 6. This dispersion ('B)
The pot life in the case of (b) varied depending on the type of inorganic blowing agent, but was at least 4 hours or more. Dispersion liquid (B)
In this case, pumps P and 4 are used to supply a fixed amount. The pot life after kneading the paste (A) and the inorganic blowing agent or dispersion (B) varies depending on the pot life of the paste (A), the inorganic blowing agent or the dispersion (B), but it is at least 5.
It was more than a minute. Therefore, from the confluence point (a) 5 to the confluence point (b) 9 of the paste (A) and the inorganic foaming agent or dispersion liquid (B)
A screw mixer, static mixer 6, etc. was used, and the passage time therein could be set within 5 minutes. Next, (c) urethane prepolymer is supplied in a fixed amount from an independent tank 7 using pumps P and 8.
Within 2 seconds after the paste (A) and the kneaded inorganic blowing agent or dispersion (B) are combined at the confluence point (B) 9 and then kneaded at high speed with a grooved screw mixer or static mixer 10. It is pushed out from the confluence point (b) 9 to the outflow point 11.

はポットライフを短くするのでこちらでは入られない。The extruded inorganic/organic composite foamed kneaded material is caught on a steel plate coil 12 (aluminum coil, paper, glass paper, asbestos paper, etc. may also be used) passing under the extrusion port, and is coated with a facing material 13 (kraft paper, polyethylene, etc.). The inorganic/organic composite foam is formed into a shape with a constant thickness using a presser roll 14 using kraft paper, asbestos paper, glass paper, etc., and then continuously cut into predetermined dimensions to form the inorganic/organic composite foam. A foam molded plate 15 is obtained. (c) Urethane prepolymer easily reacts with water, so use cleaning thinner (D) when stopping foam production.
Clean the thinner tank! 6 to pump P417,
A water tank so that it can be supplied to the confluence point (b) 9 and washed, and also to wash the inside of the static mixer 6! The paste (A) and the inorganic foaming agent or dispersion liquid (B
) is discharged. In the manner described above, it was possible to continuously produce an inorganic/organic composite foam. (Means/Features for Solving the Problems) The present invention solves the problem by dividing the kneading procedure into various ways for the inorganic/organic composite foamable composition referred to in the present invention, which has a complicated foaming reaction and is thought to be impossible to produce in a factory. While experimenting with pot life, foaming properties, etc., we found a practical dividing method and kneading procedure, and solved the problems by incorporating the most appropriate kneading means and safety measures into the manufacturing process. did. That is, in the formulation, (a) the inorganic filler and (

。The kneaded paste (A) thus obtained had the lowest pot life of 4 hours. Next, (b) the inorganic blowing agent was kneaded in a fixed amount with the paste (A) as it was, or it was dispersed in water to make it easier to knead (D) so that it could be supplied in a fixed amount.The pot life of this inorganic blowing agent was In addition, the pot life of the dispersion (B) was the lowest, 4 hours.Furthermore, the pot life of the dispersion (B) was 4 hours. When life was measured, the minimum time for subsequent formation of a stable foam was 5 minutes.Additionally, the paste (A
), an inorganic blowing agent or its aqueous dispersion (B), and a urethane prepolymer (c) were kneaded, and the shortest foaming initiation time was 2 seconds. After finding the stabilization time for each group as described above, we assembled a flow sheet and adopted the appropriate format for each process, making continuous production of foam possible.

。(1) [1] Composition and composition ratio of the composition: (a) Inorganic filler: 100 parts by weight (b) Inorganic blowing agent: 1 to 40 parts by weight based on (a) (c) Urethane prepolymer (a) Against 2-4
0 parts by weight (d) Reaction rate modifier (a) 0.1 to 20
Part by weight (e) Additive 0 to 20 parts by weight based on (a) (f) Water 10 to 200 parts by weight based on (a) of inorganic and organic In producing the composite foam, [2] As a kneading procedure during production, (i) (a) inorganic filler, (d) reaction rate modifier, (
e) Additives and (f) water are kneaded to form a paste to form independent channels. (ii) (b) Either create a path to supply a fixed amount of the inorganic blowing agent in its powder state, or (f) knead water and (b) the inorganic blowing agent to form a dispersed state and form an independent flow path. Make it. (iii) Depending on the composition ratio, (i) and (ii) are supplied independently and then integrated into one, kneaded with a screw mixer or static mixer and sent out, or
After continuously sending out only the capacity that can be consumed within minutes by batch-type kneading using two kneaders alternately, (iv) depending on the composition ratio from another independent flow path, (c) urethane prepolymer All the material that has been kneaded in a short time (about 2 seconds) by screw kneading, equilibrium kneading, or spray kneading is allowed to flow out of the kneading section, and the foam is then pressed through a face material such as kraft paper with a roll. A method for producing an inorganic/organic composite foam characterized by continuous formation. (v) A method for producing an inorganic/organic composite foam, characterized in that the kneading part of the urethane prepolymer and paste in the kneading part (iv) can be cleaned with a solvent if necessary.
