Problems solved by technology

[0007] Another glass material that can be recycled and reused in its original purpose also has the water-blocking effect of natural stone and cannot be decomposed by organisms.
In particular, once glass products are discarded without recycling, it will not only cause a heavy load on the landfill, but will not be decomposed by organisms. If they are disposed of in an incinerator, they may cause damage to the furnace body.

Embodiment 1～5 and comparative example 1

[0043] The water-stop and heat-insulation composite powder samples of each embodiment and comparative example were mixed and prepared according to the composition ratio in Table 1, and the water permeability of each sample was tested; the test results are shown in Table 1. Among them, the water-stop and heat-insulating composite powder samples of Examples 1-5 have the water-stop and leak-proof effect without water seepage, while the water-stop and heat-insulation composite powder sample of Comparative Example 1 cannot achieve the water-stop and leak-proof effect.

Abstract

The invention discloses water-stopping and thermal-insulation compound powder. The water-stopping and thermal-insulation compound powder is formed by mixing 40-80% of modified calcium carbonate waterproof powder and 20-60% of glass powder, wherein the modified calcium carbonate waterproof powder is of a core-shell structure, calcium carbonate stone powder is of a core structure, and the surface ofthe core structure is coated with a stearic acid surface layer to form a shell structure; the coating weight of the stearic acid surface layer accounts for 0.1-7.0% of the total weight of the modified calcium carbonate waterproof powder. The compound powder has waterproof and thermal-insulation properties, regeneration and reuse of recycled waste glass products are promoted, the consumption of natural ore resources can be reduced, and the environmental pollution can be prevented.

Description

technical field [0001] The invention relates to a water-stop and heat-insulating composite powder, in particular to an environment-friendly water-stop and heat-insulating composite powder mixed with glass powder. Background technique [0002] In order to achieve the heat insulation effect, most of the current buildings are laid with heat insulation materials such as heat insulation bricks, foamed cement and Styrofoam on the top floor or floor of the building, but these heat insulation materials only have heat insulation effect The leak-proof and water-proof effect of water flow seeping into the building is then not good. [0003] In order to solve the problem of waterproofing and heat insulation at the same time, another kind of waterproof and heat insulation structure of buildings, such as figure 1 As shown, on the top floor or the floor slab 10 of the building, a water-stop and heat-insulating powder layer 20, a PE foam board layer 30 and a concrete layer 40 are laid sequ...
