JPS63278803A - Process simultaneously aligning foamed concrete on surface of grc cement mortar mixed with self emulsifiable epoxyresin - Google Patents

Abstract

PURPOSE:To contrive to provide composite faculty with perfect water proof, preventing, property of neutralization, high strength, chemicals resistance and abrasion resistance, while the water proof treatment of a foamed heat insulating plate is unnecessary by a method in which emulsion resin made with self emulsifiable epoxyresin and pure water is mixed with cement and aggregate, and the mortar thus made is poured in a mold, and then vibration is applied thereto, and further cement and Al powder compounded mortar is caused to flow on the surface of GRC reinforced cement mortar with reinforcing lining and is foamed and cured with vapor. CONSTITUTION:Nonsolvent epoxyresin (Eponikke EP #910 main agent made by Nippon Chemi cal Construction Company) and self-emulsifiable curing agent (Eponikke EP #910 curing agent made by Nippon Chemical Construction Company) are mixed with pure water, thereby making emulsion resin. Cement is mixed with cristobalite component compounded aggregate, and the resin mortar made with emulsion resin is poured in the mold frame made of silicon compounded resin. Then, when vibration is applied thereto by an electric vibrator, the resin mortar aggregate is settled, and the resin cement floats up to upper surface. Then a reinforcing fiber mat is placed, and by using air vent roll the mat is rolled so as to be pushed into the resin mortar. On the fiber reinforced plate thus made, the foaming mortar in which cement is mixed with Al powder is poured and foamed and cured with vapour into a form.

Description

[Detailed description of the invention] An emulsion resin is made by mixing a solvent-free epoxy resin and a self-emulsifying hardening agent with fresh water, and a resin mortar is made from the emulsion resin by mixing cement and cristobalite-based component-containing aggregate, and a silicone-containing resin mold is made. When it is poured into a frame and vibrated with an electric vibrator, the resin mortar aggregate will rise to the bottom and the resin cement will rise to the top. At that time, a reinforcing fiber mat is placed and an air removal roll is used.
The mat was pushed into the mortar using an air removal roll to create a fiber-reinforced cement board, on which foamed mortar mixed with cement and aluminum powder was poured and foamed steam cured.
RC reinforced cement foam insulation board simultaneous shaping method, solvent-free epoxy resin compounded GRC cement board is completely waterproof, neutralization prevention, high strength chemical resistance, wear resistance, and can be left molded simultaneously with foam concrete board, foam insulation board It does not require waterproofing of the board and has multiple functions.

) Fresh water H2O (Example) When mortar mixed with A + B is poured into a plywood formwork lined with silicone-containing polysheet and an electric vibrator is applied, the aggregate part will float to the bottom and the resin mortar part to the top. After stopping the electric vibrator, place a reinforcing fiber mat on its surface and run an air removal roll to sink the mat into the mortar, allowing the air in the mortar to be removed at the same time.
GRC reinforced reinforced mortar board complete mold, next, mix 0.5 kg of clean water with C foam cement, pour it on the reinforced mortar board surface and perform foaming steam curing. After complete hardening, remove the mold and dry curing. I will do it.
