Abstract

The invention discloses a preparation technique of a waste residue composite light-weight thermal-insulation wallboard, which comprises the following steps: preparing a waste residue base material; preparing a composite admixture A; preparing waste residue light-weight aggregate; preparing a composite admixture B; preparing a wallboard blank material; preparing a wallboard blank; putting the wallboard blank in a curing chamber, and curing in a 75-80 DEG C saturated steam environment for 4-5 hours; and when the difference between inside temperature and outside temperature of the curing chamber is 25-40 DEG C, putting the wallboard blank outside the chamber, and demolding to obtain the waste residue composite light-weight thermal-insulation wallboard. According to the preparation method disclosed by the invention, the wallboard blank can be cured and demolded within 8.5-12 hours, and the demolded wallboard can be immediately put into engineering use, thereby shortening the processing cycle, and preparing the high-strength favorable-water-resistance light-weight wallboard under the conditions of changing wastes into valuable substances and using low production cost. The wallboard can be widely used in various types of construction engineering.

Description

Technical field [0001] The present invention involves a preparation method for building materials. Specifically, it is a preparation process for a composite light insulation wall board for waste residue. Background technique [0002] With the continuous development of urban buildings, in order to save space and reduce load, non -loading walls inside various types of construction projects generally use lightweight wall plates.At present, there are many types of lightweight wall boards on the market, their preparation methods are very different, and the performance of use is uneven.From the perspective of users, the lightweight wall boards prepared by the existing technology generally have problems with low intensity and poor waterproof performance, especially in the use of water body engineering projects.It is said that there are problems with high material prices, long maintenance time, slowering, long mold turnover time, and low -end product performance. [0003] In order to sol...
