A permanently modified desulfurized gypsum composite thermal insulation formwork and its manufacturing method

Abstract

The invention discloses a permanent modified desulphurization gypsum compound heat-insulating template which is prepared by the following steps: smearing an adhesion agent outside a polyurethane plate; then smearing modified desulphurization gypsum slurry outside; and filling a reinforcing material in the modified desulphurization gypsum slurry, wherein the modified desulphurization gypsum slurry is prepared by mixing desulphurization gypsum, a mineral activator, a light heat-insulating aggregate and various additives which are uniformly stirred with water. The template disclosed by the invention has the advantages that production process and flow are simple, the cost is low, the efficiency is high, the yield is large, manpower, material and financial materials are saved, a lot of waste solids are used, and thus the template is energy-saving and environmental-friendly. The integral product is small in heat conductivity coefficient and meets a relatively high building energy-saving standard.

Description

technical field [0001] The invention belongs to the field of building energy saving and structural integration, and specifically relates to a permanently modified desulfurized gypsum composite thermal insulation template. Background technique [0002] According to the development trend, building energy saving and structural integration have become the mainstream, and the current permanent non-demolition formwork has played a great role. However, the cement slurry used in permanent demolition-free formwork today has a long cement hydration cycle. It needs to be placed for more than 8 hours to turn over the plate and apply the slurry on the other side. It requires a large number of molds, takes up a lot of space, small output, large investment, and manufacturing costs. high. The energy saving rate of the building has increased to 75%. The traditional permanent formwork without demolition is difficult to meet the requirements. Even if it can be achieved by thickening the mater...

However, the cement slurry used in permanent demolition-free formwork today has a long cement hydration cycle. It needs to be placed for more than 8 hours to turn over the plate and apply the slurry on the other side. It requires a large number of molds, takes up a lot of space, small output, large investment, and manufacturing costs. high

The energy saving rate of the building has increased to 75%. It is difficult for the traditional permanent non-demolition formwork to meet the requirements. Even if it can be achieved by thickening the material, there will be great safety hazards
