Description
Technical field
The invention belongs to building material field, more particularly, it relates to a kind of high water proofing property heat preservation rock plate and its manufacture
Method.
Background technology
In building external envelope structure, main moisture source mainly has the rainwater of outside and the surface on the outside of system
Condensed water.Either roofing or external wall structure, should all avoid steam stop in systems from condensing, because the long-time of steam
Permeating the combination property to whole building structure can all have very big negative effect, therefore insulation material need to have certain draining
Function.Regardless of whether being located in advance come the waterproof for carrying out material using aluminium foil composite rock wool material or using integral waterproofing ventilated membrane
, all there is drawback in actual engineer applied in reason：The excessive permeation barrier that such as aluminium foil is formed, can cause water to steam in warm season
The condensation of gas.Therefore, late 1990s, rock cotton board is introduced into the country, through the fast development of more than 10 years, has obtained wide
General accreditation, becomes the preferred option of numerous engineering projects.
Have many with regard to the research report of rock wool material at present, e.g., Chinese Patent Application No. is 201410769754.3, Shen
Please date of publication be that in April, 2015 application documents of No. 22 disclose a kind of production method of three-dimensional structure rock wool, including molten slurry, into
The steps such as fine, paving cotton, pressure cotton, solidification, finishing, wherein in pressure cotton step, the pressure cotton machine of employing is three-dimensional rock wool pressure cotton machine, with
Conveying rock wool layer is pressed into there is mutual bridging arrangement between rock wool layer so as to form three-dimensional integrally-built rock wool product.
But the water proofing property and drain function of the rock cotton board disclosed in the patent are general, it is impossible to meet the demand of building external envelope structure.
And for example, Chinese Patent Application No. is 201620114869.3, and authorized announcement date is that in August, 2016 patent application document of 17 days is public
A kind of compound vertical hair rock cotton board of ceramic wool orientation has been opened, it is described perpendicular including the vertical hair rock wool flaggy and ceramic wool layer that are mutually bonded
Silk rock wool flaggy includes vertical hair rock wool substrate, and the vertical hair rock wool substrate is formed by mineral wool block cutting, if the mineral wool block includes
Dry is bond layer between the adjacent rock cotton board along silk along silk rock cotton board, and the vertical hair rock wool substrate surface is filled with bonding
Agent, the ceramic wool layer surface is coated with ceramic wool curing agent, and the orientation rock cotton board in the patent is by several different types
Rock cotton board bonding formed, be not be directly produced and obtain by improving the raw material composition of rock cotton board, therefore the rock in the patent
Occlusion is not crosslinked between cotton flaggy, there are problems that fastness is poor, bonding agent consumption, and in the rock cotton board of the patent
The hydrophobicity of vertical hair rock wool is general, affects its using effect.
Rock cotton board weak point present in practical engineering application promotes the generation of orientation rock cotton board.Orientation rock cotton board
It is that Luo Kewei groups propose first.Wherein " orient " and refer to that rock cotton board has directionality, that is, positive and negative when installing, due to fixed
Structure to rock cotton board is special, while density is reduced, original mechanical strength can be ensured or even improve, so as to save into
This simultaneously substantially reduces difficulty of construction.With regard to orient rock cotton board research China report it is few, although orient rock cotton board have
Numerous advantages, but its space that still has greatly improved in terms of water proofing property.
