Abstract

The invention discloses a method for producing an energy-saving external wall building material from desert sand as a raw material. The method comprises the specific steps as follows: sand is screened, the screened sand is subjected to acid pickling with hydrochloric acid for removal of impurities and sludge on the sand surface, and the obtained sand is aired in a baking manner; an inorganic curing agent is added and fully mixed through stirring, so that the sand surface is cured and the single sand hardness is improved; inorganic toner is heated to be completely liquefied; the sand, grapheneand the liquefied inorganic toner are injected into a calcinator and fully mixed in the calcinator through stirring, the toner and the graphene are completely attached to the sand surface, ceramic crystal sand particles are obtained after cooling, and a finished product is obtained. The utilization problem of a large amount of desert sand at present is solved, a new way is developed for productionof the external wall building material, self-cleaning, high heat insulating property, high hardness, good flexibility and other performance of the graphene are fully played, and the finished producthas the same performance in construction effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for making energy-saving exterior wall building materials by using desert sand as a raw material. Background technique [0002] With the development of the construction industry, the amount of materials used for exterior wall construction has increased dramatically. The manufacture of exterior wall building materials is usually made of river sand, lake sand, sea sand or ore rocks combined with other components, but the country has restricted the excessive mining of river sand, lake sand and sea sand, and uses crushed ore rocks Sand not only consumes high energy, but also pollutes the mine environment. At the same time, only limited river sand or rock-breaking machine-made sand can no longer meet the needs of the huge construction market, thus forming a shortage of construction sand resources. [0003] On June 17, 2006, the State Forestry Administration announ...
