Problems solved by technology

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. One of them is widely used. Usually, the lower insulation board is a rigid foam plastic board made of resin as raw material plus other raw and auxiliary materials and polymers. It is heated and mixed while injecting a catalyst, and then extruded and formed. It has certain good moisture-proof, waterproof, and heat-insulating properties, so as to achieve the effect of energy saving and environmental protection. However, this kind of plastic insulation board mainly made of resin still has the following problems after continuous improvement and perfect performance: 1. Bending resistance Low compressive strength; 2. Poor fire resistance; 3. High dry density and heavy finished product

Abstract

The invention discloses a high-strength light insulation board and a production method thereof. The high-strength light insulation board comprises, by weight, 40-60 parts of desulfurized gypsum, 20-30 parts of artificial fibers, 10-20 parts of calcium oxide, 10-20 parts of attapulgite, 5-15 parts of polyurethane, 8-12 parts of polystyrene, 2-4 parts of auxiliaries and 20-30 parts of water. The auxiliaries include foaming agents, early strength agents and water repellents. The preparation method of the insulation board includes the steps: firstly, conveying the desulfurized gypsum, the calcium oxide and the attapulgite into a tubular ball mill for grinding; secondly, conveying grinded raw materials and residual raw materials into stirrer for mixing and stirring; thirdly, injecting the raw materials into a mold by air pressure and extruding the raw materials; finally, performing steam curing on the formed insulation board. The insulation board has the advantages of high fracture resistance and tensile strength, good fireproof performance, light weight and the like. The raw materials are wide in source, simple to prepare, low in cost and suitable for large-scale production, development of energy-saving and environment-friendly building materials is promoted, and living safety and comfort of people are improved.
