Problems solved by technology

However, with the increasing demand for use, in order to ensure that no bacteria or dirt will grow between the rock wool insulation board and the installation site, the requirements for its waterproof and air permeability are also getting higher and higher. Cotton insulation board is slightly inferior in air permeability

Abstract

The invention provides a waterproof breathable rock wool insulation board. The insulation board comprises an upper waterproof layer, an intermediate layer and a lower waterproof layer from top to bottom; the surface of the upper waterproof layer is uniformly provided with hydrophobic protrusions; the intermediate layer is prepared from the following components in parts by mass: 17 to 23 parts of cement, 11 to 15 parts of quartz sand, 5 to 9 parts of glue and 3 to 6 parts of auxiliary material; the auxiliary material is prepared from the following components in parts by mass: 5 to 8 parts of polyvinyl alcohol, 3 to 7 parts of silicon dioxide aerogel, 3 to 5 parts of hydrogen peroxide, 1 to 3 parts of aluminum phosphate solution and 1 to 3 parts of water reducing agent. The insulation board of the invention has the advantages of good heat insulation effect, good waterproof and breathable effect, high weather ability, environmental protection and non-toxicity, has excellent use effect both indoors and outdoors, and is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a waterproof and breathable rock wool thermal insulation board. Background technique [0002] Rock wool insulation board is made of basalt and other natural ore as the main raw material to make discontinuous fibers, adding a certain amount of binder and other auxiliary agents, and then making plate-shaped products with different densities through sedimentation, curing, cutting and other processes. It is used for heat insulation and sound insulation of industrial equipment and buildings, etc. However, with the increasing demand for use, in order to ensure that no bacteria or dirt will grow between the rock wool insulation board and the installation site, the requirements for its waterproof and air permeability are also getting higher and higher. Cotton insulation boards are slightly less breathable. [0003] Therefore, in order to solve the above problems,...
