Abstract

The invention relates to a foam powder insulation wall hollow brick and method for the production thereof. The hollow brick comprises the following components by a weight ratio of cement: urea-formaldehyde foam powder: aggregate: PVA powder: water is 8-25:35-55:40-70:1- 8:0.1-2. The foam powder insulation wall hollow brick has advantages of simple preparation, low production cost, environmental friendliness, non-environment pollution, good compressive strength and good seismic performance. The inventive hollow brick requires no external wall heat insulating engineering in the south owing to the low thermal conductivity and saved energy. The hollow brick is easy-to-get in raw material and suitable for large production.

Description

technical field [0001] The invention relates to a hollow brick and a preparation method thereof, in particular to a hollow brick for a foam powder insulation wall made of urea-formaldehyde foam plastic powder and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, people's demand for new thermal insulation and environmental protection wall materials is becoming more and more urgent. For this reason, the publication number is CN1474010, the publication date is 2004.02.11, and the patent number is 03133634.5. Light aggregate concrete small hollow block and its preparation method” discloses a hollow block, the structure of which is a lightweight hollow middle layer sandwiched between two panels, wherein the raw material used for the panels is cement , mineral powder, water and early strength agent, the raw materials used in the middle layer are cement, mineral powder, foam plastic, special glue for mortar, water a...
