Problems solved by technology

The production temperature of this method is high, colloid mill high-shear treatment is required, resource consumption is large, equipment cost is high, and asphalt and heat transfer oil volatilize at high temperature, resulting in serious pollution. After heat transfer oil volatilizes, the effect of promoting melting and improving flexibility cannot be achieved. Easy to age and crack, easy to break, the mineral particles on the surface of the product are easy to fall off, poor aging resistance, and short service life
At the same time, the obtained asphalt bricks do not have flame-retardant and heat-insulating properties

Abstract

The invention relates to a heat-insulation flame-retardant lightweight wall tile and a preparation method thereof. The wall tile comprises a glass fiber body, a modified asphalt coating and a facing material layer; the modified asphalt coating adopts the following raw material formula in percentage by weight: 40 percent to 60 percent of 10# petroleum asphalt, 3 percent to 5 percent of 90# road asphalt, 1 percent to 3 percent of a polyolefin processing modifier, 15 percent to 25 percent of magnesium hydroxide, 6 percent to 12 percent of rubber powder and the balance of filling; and the facing material layer adopts the following raw material formula in percentage by weight: 30 percent to 40 percent of hollow ceramic microbeads, 2 percent to 5 percent of powder butadiene styrene rubber and the balance of color sand. The wall tile disclosed by the invention has excellent corrosion resistance, waterproofness and aging resistance, high tensile strength and excellent cutting processing performance, is simple to construct, is attractive and elegant, particularly has excellent heat insulation and flame retardance performance and implements environmental-friendliness, energy conservation, safety and reliability of an external wall decoration material.

Description

technical field [0001] The invention relates to a lightweight wall tile and a preparation method thereof. Background technique [0002] As an easy-to-construct building exterior wall decoration material, lightweight wall bricks not only have good decorative and aesthetic effects, but are also mainly used to protect the wall from external erosion and damage, and the comprehensive cost is low, and the later maintenance is convenient. Many are applied to modern architecture. [0003] In recent years, due to changes in architectural design and the use of new building components, higher and higher requirements have been placed on facade materials. On September 25, 2009, the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development jointly issued the "Interim Regulations on Fire Protection of Civil Building External Thermal Insulation Systems and Exterior Wall Decoration", which requires that the building facades must reach the fire protection level B1, ...
