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, and in particular relates to an energy saving panel for building walls. The energy saving panel comprises panels which are arrangedoppositely up and down, and each panel is compounded of a light sound insulation panel and a light heat insulation panel. The two panels are connected with each other through a sliding piece, and a first clamping piece and a second clamping piece are respectively arranged at the two ends of each panel. When two energy saving panels are connected, the second clamping piece can be inserted into thefirst clamping piece to prevent falling off. Compared with the prior art, the adjacent panels are transversely locked through the first clamping piece and the second clamping piece, and the construction is simple and efficient. By the relative sliding between an upper sliding block and a lower sliding block, pressure is relieved so that the panel has a buffering effect. The vertical staggered peaks are formed between each layer of energy saving panel, so the integrity and stability of the wall are enhanced. The light sound insulation panel is compounded of a borosilicate-modified phenolic laminate and borosilicate-modified phenolic foam, so that the light sound insulation panel has a good sound absorption performance in medium and low frequency, and the sound absorption coefficient reach up to 0.69. The energy saving panel has good heat resistance, heat insulation and flame retardant properties.

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...
