Vacuum insulation plate and preparation method thereof

Abstract

The invention discloses a vacuum insulation plate which comprises a lower box body, a high temperature resistant O-type seal ring and an upper seal cover, wherein the lower box body is made of rigid PVC and the upper surface of the lower box body is provided with an opening; the upper seal cover is made of stainless steel; a vacuum seal cavity wrapped by the upper seal cover, the high temperature resistant O-type seal ring and the lower box body is formed. The structure and insulation theory of the vacuum insulation plate provided by the application are based on the vacuum structure and vacuum insulation theory of a stainless steel vacuum insulation cup. The vacuum insulation plate provided by the application also has a support framework function, a vacuum seal function, a fire-fighting function and a vacuum insulation function; the vacuum seal function and vacuum insulation function are realized by virtue of the lower box body and the upper seal cover together; Since the lower box body and the upper seal cover are rigid, and have less possibility of being pierced by sharp objects and hard objects during conveying, storage and construction processes, breakage and air admission of the vacuum seal cavity are avoided, and the problem that an existing vacuum insulation plate becomes invalid easily can be solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a vacuum insulation panel and a preparation method thereof. Background technique [0002] my country's building energy consumption accounts for about 30% of the country's total energy consumption. Building energy conservation is a very important task to alleviate my country's energy shortage, improve people's living and working conditions, reduce environmental pollution, and promote sustainable economic development. Building energy conservation mainly includes three parts: thermal insulation of building roofs, thermal insulation of building exterior maintenance walls and exterior doors and windows, and energy conservation of building equipment. In October 2007, the state issued a document requiring that new buildings across the country must be insulated, and existing buildings are also required to undergo energy-saving renovations within a time limit. [0003] The ext...
