Fly ash foamed plastic particle insulating and waterproof material, and manufacturing method thereof

Abstract

The invention relates to a fly ash foamed plastic particle insulating and waterproof material, and a manufacturing method thereof. The material is composed of raw materials of: cement, test-proved 32.5 ordinary Portland cement, quick lime containing 80 to 85% of CaO, polystyrene foamed plastic particles with a granularity of 4 to 8mm, and fly ash. Fly ash, quick lime and cement are placed in a mixer according a certain ratio, and are mixed for 0.5 to 5 minutes, such that a cementing material is manufactured. A proper amount of a cementing material, polystyrene foamed plastic particles and water are added to the obtained cementing material. A foaming agent and a water-proofing agent are added to the obtained mixture, and the mixture is stirred for 0.5 to 5 minutes, such that foamed slurry is manufactured. The foamed slurry is used for casting within 30 to 60 minutes. A cast surface is compacted and smoothed, and is maintained moisturized for 12 to 72 hours, such that an insulating and waterproof plate is manufactured. The surface of the plate is then processed through a surface spraying treatment 3 to 5 times by using a hydrophobic agent with intervals of 1 to 3 hours. The material provided by the invention has advantages of low density, high strength, good heat insulation, good waterproof performance, and low manufacturing cost. With the invention, wastes such as fly ash and foamed plastic particles can be reused, and a large amount of clay is saved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal waterproof material of fly ash foamed plastic particles and a production method. Background technique [0002] With the rapid development of our country's economy, various construction projects are under construction, and the required building materials are increasing rapidly. On the other hand, in order to protect the cultivated land, the country imposes strict restrictions on the use of clay bricks, which promotes various new types of clay bricks. There are four types of building materials: aerated concrete, ceramsite concrete, foam concrete, and macroporous concrete. Their common disadvantages are poor thermal insulation and heat insulation, which do not meet the requirements of energy saving and emission reduction. And the manufacturing cost is high. It is particularly necessary to invent a new type of building material with good thermal insulation and...
