Embodiment 1

[0031] The first step: spread a layer of polytetrafluoroethylene release paper on the operating platform, and use the LGPQ12CB high-pressure airless sprayer of Shanghai Liangshi Spraying Equipment Co., Ltd. to evenly spray 2127 dissolved in ethanol with a concentration of 70%. Type phenolic resin, the spraying amount of each layer of phenolic resin is 141g / m 2 , and then lay a layer of glass fiber needle felt at an angle of 0 degrees, and then spray 2127 type phenolic resin evenly, lay a layer of glass fiber needle felt at a 0 degree angle, and so on until all the glass fiber needle felts are laid , and then spray 2127 type phenolic resin evenly, and cover with a layer of release paper. The number of layers of glass fiber needle felt is 7 layers, the thickness is 3mm, and the bulk density is 100kg / m 3 . The mass ratio of 2127 type phenolic resin to glass fiber needle felt is 100:185.

Abstract

The invention belongs to the technical field of composite fireproof heat insulation materials, and relates to a composite lightweight sheet material and a preparation method thereof. The composite lightweight material comprises a plurality of layers of structure acupuncture fiber felt layers and thermosetting phenolic resin layers which are alternatively paved, wherein the uppermost layer and the lowermost layer of the lightweight composite sheet material respectively are the thermosetting phenolic resin layer. Compared with existing heat insulation materials, the fireproof heat insulation composite lightweight sheet material provided by the invention has the advantages of light weight, high strength, good waterproof property, good fireproof property, and good heat and sound insulation property, overcomes the disadvantages of inflammability, easy effloresce and large brittleness of the existing heat insulation materials, improves the compression strength of products, and is convenient to construct.

Description

technical field [0001] The invention belongs to the technical field of composite fireproof and thermal insulation materials, and relates to a composite lightweight board and a preparation method thereof. Background technique [0002] In recent years, fires caused by insulation materials have been heard from time to time in our country, and the frequency and huge loss of personnel and property are shocking. Throughout the thermal insulation market, the commonly used thermal insulation materials mainly include expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), and polyurethane foam (PU). EPS, XPS, and PU are all organic thermal insulation materials, which are light in weight, good in heat preservation and heat insulation, but have poor fire prevention and safety, and are easy to age and burn. Even sparks from electric welding can set these insulations on fire. When burning, the smoke is large and the toxicity is high. Especially EPS foam and XPS foam have ext...
