Problems solved by technology

[0006] Aiming at the problems of unstable hydrophobic performance and insufficient mechanical strength of the existing rock wool boards, one of the purposes of the present invention is to provide a high waterproof thermal insulation rock wool board, which is made of iron ore, perlite, slag and glass, etc. Minerals are manufactured according to a certain ratio, and a certain amount of water-repellent and adhesives are added in the process, so that the rock wool board has a reasonable density gradient. The surface layer of the rock wool board has a high density, a dense fiber structure, and a large water absorption performance. Reduced, thereby improving the hydrophobic performance of the entire system structure

Abstract

The invention discloses a high-waterproofness heat preservation rock wool board and a manufacturing method thereof and belongs to the field of building materials. The rock wool board is made from the raw materials of, by weight, 55-65 parts of iron ore, 10-15 parts of perlite, 12-16 parts of slag, 10-13 parts of glass, 6-8 parts of a water repellent, 5-6 parts of urea, 8-10 parts of phenol-formaldehyde resin, 1-2 parts of 3-aminopropyltriethoxysilane and 3-5 parts of vinyltri tert-butyl peroxide silane. By adoption of a formula of the rock wool board, the proportion of manganese, calcium and iron can reach triangular balance, high-quality rock wool fibers are obtained and used in cooperation with the water repellent and a bonding agent to enable the rock wool board to have a reasonable density gradient, the rock wool board is high in surface layer density and compact in fiber structure, the water absorption capacity is greatly lowered, and therefore the hydrophobic property of the whole system structure is improved.

Description

technical field [0001] The invention belongs to the field of building materials, and more particularly relates to a high waterproof thermal insulation rock wool board and a manufacturing method thereof. Background technique [0002] In the building envelope, the main sources of moisture are external rainwater and surface condensation near the outside of the system. Whether it is a roof or an external wall structure, the retention and condensation of water vapor in the system should be avoided, because the long-term penetration of water vapor will have a great negative impact on the comprehensive performance of the entire building structure, so the thermal insulation material needs to have a certain drainage function. Whether the use of aluminum foil composite rock wool material or the use of the overall waterproof breathable membrane for the waterproof pretreatment of the material, there are disadvantages in practical engineering applications: for example, the excessive perm...
