Problems solved by technology

External wall insulation is the most direct and effective method in building insulation. However, due to various uncertainties in on-site construction, the bonding strength between the insulation board and the outer hardened insulation layer cannot be guaranteed, so it is necessary to glue each layer in the factory. The knot is tight, and the finished product only needs to be fixed by bonding and buckling during construction, which greatly reduces the construction strength and the probability of failure to meet the strength standard

Abstract

The invention discloses an EPS lightweight aggregate thermal-insulation decorative all-in-one board, and a preparation method thereof. The EPS lightweight aggregate thermal-insulation decorative all-in-one board comprises a thermal insulation inner core, a fiber grid cloth, a hardened layer, and a stone-like coating decorative layer successively from inner to outer; by weight, the thermal insulation inner core comprises 30 to 50 parts of EPS foam particle, 40 to 80 parts of iron tailing sand, 200 to 300 parts of Portland cement, 10 to 20 parts of rubber powder, and 10 to 20 parts of hydroxymethyl cellulose. According to the preparation method, the flame-retardant EPS foam particle is taken as a lightweight aggregate to prepare the thermal insulation inner core, EPS foam is ultra low in heat conductive coefficient, so that the whole board is provided with excellent thermal insulation performance. The EPS lightweight aggregate thermal-insulation decorative all-in-one board is excellent in thermal insulation effect, and low in density, is simple in preparation technology, and is convenient for large scale production.

Description

technical field [0001] The invention belongs to the field of building heat preservation materials, and in particular relates to an EPS light aggregate heat preservation and decoration integrated board and a preparation method thereof. Background technique [0002] At present, energy consumption is becoming more and more serious, and the energy dissipated by buildings accounts for a large proportion. Therefore, building insulation is of great significance to the current energy environment. External wall insulation is the most direct and effective method in building insulation. However, due to various uncertainties in on-site construction, the bonding strength between the insulation board and the outer hardened insulation layer cannot be guaranteed, so it is necessary to glue each layer in the factory. The knot is tight, and the finished product only needs to be fixed by bonding and buckling during construction, which greatly reduces the construction strength and the probabili...
