preparation example Construction

[0028] The foaming aid is potassium hydroxide, in which the content of KOH is 95-98%. Before foaming, KOH and Na 2 B 4 o 5 (OH) 4 ·8H 2 O and SiO in soda lime glass 2 , CaO reaction to produce KNaCaSi 2 o 6 ·6H 2 O crystal, KNaCaSi 2 o 6 ·6H 2 During the heating and foaming process, the O crystal releases steam to make the raw materials foam. This method increases the foaming porosity, and the foaming process is stable. The generated pores are small and evenly distributed, which can effectively absorb sound waves and greatly enhance To ensure the sound insulation effect of foam glass, the foam stabilizer is a mixture of foam stabilizer silicone amide and sodium lauryl sulfate, its mass ratio is 1.5-2:1-1.2, the auxiliary additive is borax, and its main component is 95.4- 98.2% Na 2 B 4 o 5 (OH) 4 ·8H 2 O, the mixed co-solvent is a mixture of ethylene glycol and glycerin, its mass ratio is 3-5:1-1.6, the silane coupling agent is anilinomethyltrimethoxysilane, and...

Abstract

The invention relates to the technical field of preparation of heat-insulating and sound-insulating composite materials, and discloses a heat-insulating poly-p-phenylene terephthalamide-foam glass sound-insulating composite material. The composite material is prepared from the following raw materials: waste glass slag, waste mineral wool board, poly-p-phenylene terephthalamide, a foaming aid, a foam stabilizer, a co-additive, a mixed co-solvent and a silane coupling agent, wherein the waste glass slag and the waste mineral wool board are recovered construction wastes such as soda lime glass wastes. The poly-p-phenylene terephthalamide-foam glass sound-insulating composite material adopts KOH as the foaming aid, and Na2B4O5(OH)4.8H2O is added as the co-additive; the KOH and the Na2B4O5(OH)4.8H2O react with SiO2 and CaO in soda lime glass to produce KNaCaSi2O6.6H2O crystals before foaming; in the heating and foaming process, the KNaCaSi2O6.6H2O crystals release steam to foam the raw materials. By adopting the method, the foaming porosity is improved, and the foaming process is stable; produced pores are very small and are uniformly distributed, so that sound waves are effectively absorbed, and the sound-insulating effect of foam glass is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of preparation of heat-insulating and sound-insulating composite materials, in particular to a heat-insulating poly-p-phenylene terephthalamide-foam glass sound-insulating composite material. Background technique [0002] Foam glass is an inorganic non-metallic glass material made of cullet, foaming agent, modifying additive and foaming accelerator, etc., after finely pulverizing and uniformly mixing, then melting at high temperature, foaming and annealing. The new material has the functions of moisture-proof, fire-proof and anti-corrosion. In addition, the glass material has the advantage of not deteriorating in long-term use. It is widely used in wall insulation, petroleum, chemical industry, noise reduction in computer rooms, electric power, military products, etc., and is called by users. Green environment-friendly insulation material. [0003] At present, most of the foam glass is inorganic non-metalli...
