Composite phenolic aldehyde building energy-saving heat-insulating board and its manufacturing method and application

Abstract

A composite phenolic aldehyde construction energy saving insulation plate and manufacturing method and application thereof relate to an insulation plate. The invention aims to provide the composite phenolic aldehyde construction energy saving insulation plate and the manufacturing method and application thereof with excellent insulation effect, convenient use and high construction efficiency. The invention comprises a phenolic aldehyde insulation layer, a bonding layer and an inorganic material composite board, wherein, the bonding layer is arranged between the phenolic aldehyde insulation layer and the inorganic material composite board; the thickness of the phenolic aldehyde insulation layer is 20-100mm, the thickness of the bonding layer is 0.1-1mm, and the thickness of the inorganic material composite board is 3-10mm. The inorganic material composite board is continuously produced for reserving; the inorganic material composite board is applied with bonding treatment agent; phenolic aldehyde resin which is prepared pro rata is frothed and solidified into shaping with the continuous production line of the composite board, and a target product can be received.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a composite phenolic building energy-saving thermal insulation board and its manufacturing method and application. Background technique [0002] Due to the high energy consumption of buildings, serious energy waste is a very common problem. Therefore, building energy conservation is a direct and inexpensive systematic project to alleviate energy shortages, improve environmental conditions, reduce environmental pollution, and promote sustainable economic development. Currently used building insulation materials, such as extruded boards, polystyrene boards, polystyrene particles, polyethylene high-foaming and other foam materials, although light in weight and acceptable in thermal insulation effects, generally have the following disadvantages: 1) flammable , toxic smoke, poor temperature resistance; 2) poor water absorption, easy to mildew in a humid environment and cause the wall to t...

Problems solved by technology

Currently used building insulation materials, such as extruded boards, polystyrene boards, polystyrene particles, polyethylene high-foaming and other foam materials, although light in weight and acceptable in thermal insulation effects, generally have the following disadvantages: 1) flammable , toxic smoke, poor temperature resistance; 2) poor water absorption, easy to mildew in a humid environment and cause the wall to turn black; 3) when the wall is insulated, the bonding ability with the bonding material is poor, For example, it has poor adhesion to gypsum materials, cement mortar, etc., and a large number of nails and anchors are needed to fix it; 4) The construction period is long and the construction procedures are complicated; 5) It cannot be combined with inorganic materials, metals, and non-metals. and textile fibers for continuous one-time molding to produce composite panels (reference: ①Lin Yancheng, Preliminary Study on Rockwool External Wall Thermal Insulation Technology, China Building Thermal Insulation Information, 2007, 7:35; ②Yang Zongkun, Current building energy conservation in China should not be ignored Big Problems, China Building Thermal Insulation Information, 2007, 8:36; ③Tian Junxian, Yang Tongxing, Board-mounted Rigid Polyurethane Foam Insulation and Decoration Integrated Board and Exterior Wall External Thermal Insulation System Research, China Building Thermal Insulation Information, 2007, 10 : 32; ④Common quality problems and solutions of EPS polystyrene board external wall external insulation engineering, China Building Thermal Insulation Information, 2007, 11: 34; ⑤Xu Shiyuan, Weak links and countermeasures of commonly used external thermal insulation systems, Anhui Architecture)

However, the application of phenolic foam currently on the market in the insulation of walls and roofs also has problems such as long construction period and complicated construction procedures.
