Sprinkling material used for surface anchoring and preparation method thereof

Abstract

The invention relates to a spray material used for surface anchorage and a preparation method thereof, which solves the technical problems of being difficult in construction, bad safety, high cost and land wasting of the existing covering measure. The spray material of the invention comprises the following components of parts by weight: 30 to 60pbw of water, 10 to 30pbw of powder coal ash, 15 to 40pbw of cement, 0.5 to 1.2pbw of adhesive powder, 2.5 to 6pbw of talcum powder, 1 to 3pbw of gypsum, 0.1 to 0.5pbw of water reducing agent and 0.1 to 0.4pbw of organic fibers. The preparation method of the invention comprises procedures that: raw material of each component is weighted and taken; the gypsum, the talcum powder, the adhesive powder, the organic fiber and the water reducing agent are put into a blender and stirred at a low speed; the water is poured into the dry mixture; low speed stirring is carried out again; the powder coal ash and the cement are added into the wet mixture; the mixture is firstly stirred at low speed and then at high speed in succession, the spray material used for surface anchorage is finally formed. The covering layer formed in the invention has good tightness, good anti-pressure and anti-breaking intensity, strong anti-moisture and bonding capacities, superior environmental protection capacity and strong anti-combustion capacity after solidification, which can prevent toxic and defilement gase from escaping. The preparation method is simple and easy for operation.

Description

technical field [0001] The invention relates to a spraying material for covering and anchoring the surface of a large-area material pile and a preparation method thereof, in particular to a spraying material for covering and anchoring the surface of a garbage pile and a preparation method thereof. Background technique [0002] Large-scale material piles, such as garbage piles, coal piles, cement slag piles, fertilizer piles, etc., may be concentrated in a specific area or location during transportation, processing or storage, and it is usually necessary to cover their surfaces A layer of anchoring material, thereby reducing or preventing dust from being blown everywhere, or preventing water pollution, preventing the emission of unpleasant gases, fire prevention, preventing material piles from being washed by rainwater to corrode and pollute the land, and preventing vectors such as birds, flies and Other insects linger on the surface of these stockpiles. [0003] Traditional...
