Sound-proof insulating board

Abstract

The invention provides a sound-proof insulating board. The sound-proof insulating plate is characterized in that each of the upper and lower surfaces of a foam board is provided with, from interior to exterior, a wood board layer, a glass fiber layer, a carbon fiber layer and a reinforced plastic layer, wherein the foam board is made of flame-retardant foam, and a layer of vinyl resin is coated on the outer surface of each reinforced plastic layer. The sound-proof insulating plate provided by the invention overcomes disadvantages in separate usage of foam and inorganic materials like fiber glass, gives full play to the characteristics of light weight and cheap price of a foamed material, has good sound-proof effect, and inherits the advantage of high strength of an inorganic material composed of glass fiber and the like; and the insulating board prepared from a combination of the materials is light in weight, low in cost, good in insulating properties and excellent in sound-proof effect. The insulating board prepared in the invention is simple, compact and reasonable in structure, convenient and fast to assemble, reliable in connection, good in insulation effect and high in strength, has good high temperature resistance, fire resistance and anti-shock and buffering effect, can prevent generation of static electricity, has prolonged service life and greatly improved reliability in usage and can be easily used and promoted.

Description

technical field [0001] The invention relates to an insulating board, and in particular provides a sound-insulating insulating board. Background technique [0002] Foam materials are used alone as insulating boards. Due to their low impact load resistance and poor bending resistance, their main functions are as packaging and cushioning fillers, which have not been used in people's lives. Separate glass fibers, etc. The cost of the finished inorganic material board is relatively high, and the sound insulation effect between the city and the city is poor, and the ideal effect cannot be achieved. Contents of the invention [0003] The object of the present invention is to provide an insulating board with sound insulation, low cost and light texture. [0004] The present invention specifically provides a sound-insulating insulating board, which is characterized in that a wood board layer 2, a glass fiber layer 3, a carbon fiber layer 4, and a reinforced plastic layer 5 are seq...
