Abstract

The invention discloses a preparation method and application of a porous capsule noise reduction and sound insulation material. The porous capsule noise reduction and sound insulation material is prepared from, by weight, 5-55 parts of red mud, 0-50 parts of other solid waste, 10-60 parts of alkali activator, 3-10 parts of foaming agent, 0.5-2 parts of foam stabilizer, 1-5 parts of fiber and 0-2 parts of retarder, and the water-binder ratio is 0.5-0.8. The foaming agent is selected from an animal protein foaming agent, a vegetable protein foaming agent, an FP type foaming agent or an AB composite foaming agent. The porous capsule noise reduction and sound insulation material is a light material formed by preparing a foaming agent solution into foams by a physical method, mixing and stirring the foams with a cementing material, water, an admixture, an additive and the like according to a certain proportion, and hardening through physical and chemical actions. The light-weight, high-strength, adjustable in strength and density, good in flowability, capable of absorbing and insulating sound, insulating heat, absorbing energy, resisting shock and the like, and the application prospect is wide.

Description

technical field [0001] The invention relates to a preparation method of a noise reduction and sound insulation material, in particular to a preparation method and application of a porous capsule noise reduction and sound insulation material. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, with the rapid development of the economy and society and the implementation of the strategy of "transportation power", the road mileage is increasing, and the traffic noise environment will bring anxiety and restlessness to the driver, affecting the driver's attention and Response speed increases driving safety hazards. In addition, the number of cars, trains, high-speed rails, and subways is gradually increasing, and their operating speeds are gradually accelerating, causing more and more serious noise pollution, seriously affecting the lives a...
