Problems solved by technology

In the process of building construction, the board will be required to have a buffering effect according to the demand, but the existing board does not have the buffering effect. However, some building materials using gypsum boards as sound insulation materials have disadvantages such as low strength, strong water absorption, and impact resistance. Wrong sides and even gaps appear, which not only affects the appearance, but also reduces the effect of noise reduction and heat preservation

Abstract

The invention relates to the technical field of building materials, in particular to an energy-saving panel used for building walls, including panels facing up and down. The panels are composed of a lightweight sound insulation panel and a lightweight heat insulation panel. The two ends of the board are respectively provided with a first clamp and a second clamp. When two energy-saving boards are connected, the second clamp can be inserted into the adjacent first clamp to prevent falling off. Compared with the prior art, the adjacent boards of the present invention are horizontally locked through the first clamp and the second clamp, and the construction is simple and efficient; through the relative sliding between the upper and lower sliders, the pressure is resolved so that the The board has a buffering effect, and a vertical staggered peak is formed between the energy-saving boards of each layer, which increases the integrity and stability of the wall. The lightweight sound insulation board is made of borosilicate modified phenolic laminate and borosilicate modified phenolic foam. It has good sound absorption performance at medium and low frequencies, the sound absorption coefficient is as high as 0.69, and it has good heat resistance, heat insulation and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-saving board used for building walls. Background technique [0002] At present, the contradiction between my country's resource and energy supply and social and economic development is very prominent. The construction and real estate industries are typical industries that consume a lot of resources and energy, accounting for more than 30% of the country's energy consumption, and are key areas for energy conservation and emission reduction. ; It is imperative to carry out building energy conservation. Building materials is a collective term for materials used in civil engineering and construction. It can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramics, glass, engineering plastics, composite materials, etc. Decorative materials inc...
