Method for preparing waterproof, antifouling, environment-friendly and flame retardant insulation board by using pitchstone beads

Abstract

The invention provides a preparation method for making waterproof, anti-fouling, environmental protection, A-level flame-retardant and heat-insulating boards with closed-cell turpentine rock puffed microspheres, including turpentine rock spheroidization treatment, high-temperature expansion sintering, proportioning, mixing, stirring, Briquetting and drying, characterized in that: 80-90wt% closed-cell turpentine hollow glass beads with a particle size of 200-250μm, 8-15wt% sodium silicate adhesive, 1-2.5wt% organosilicon water-repellent, Stir the paste in a mixer for 2 minutes with a water-cement ratio of 0.3-0.4 (W / C), pour it into a test mold, and compact it on an 80-ton press with a compression ratio of 1.8-2:1. After drying, a layer of anti-aging anti-fouling paint is directly sprayed on the outer surface of the insulation board, and the waterproof, anti-fouling, A-class flame retardant, thermal conductivity, and compressive performance tests are carried out.

Problems solved by technology

[0002] At present, there are many kinds of insulation boards for walls at home and abroad. Most of the insulation boards are processed by organic synthesis methods. Commonly there are phenolic boards, polystyrene boards, extruded boards, cement foam insulation boards, etc. The common feature is that chemical organic materials are Made of raw materials, it has the advantages of light weight, small bulk density, excellent thermal insulation, chemical corrosion resistance, closed-cell hydrophobic structure, no water absorption, toughness, water resistance, fiber toughening, etc. It has crack resistance It can be used for internal and external thermal insulation, and has been widely used in building energy-saving demonstration projects. On the other hand, since organic boards are processed from organic matter, in actual construction, bonding Low strength, short bonding time, easy to fall off, difficult to treat and degrade waste, and become white pollution that endangers the atmosphere and groundwater environment. At the same time, harmful substances are gradually released. As an indoor thermal insulation material, it will cause harm to the human body and is flammable during use. , and the ignition point is low, the fire performance is poor, the high temperature produces harmful gases, and with the prolongation of use time, cracks, shrinkage and other phenomena will occur; Very large, high breakage rate, poor thermal conductivity, poor crack resistance, its application has great limitations, the thermal conductivity is 0.07 ~ 0.08W / m.k; the energy saving effect is poor, and the thermal performance needs to be further improved

[0003] The ignition point of the organic board is low, generally at 70-80 degrees, and the current fire-fighting equipment in high-rise buildings cannot reach it, the burning speed is fast, and it is easy to produce toxic gases, causing suffocation and death of people in the room, and causing major property losses in a short time. It is imperative to use internal and external fireproof and thermal insulation materials
