Embodiment Construction

[0030] Process flow of the present invention such as figure 1 Shown, the present invention is specifically described below according to accompanying drawing;

[0031] (1) Definition of glass wool:

[0032] Glass wool is a category of glass fiber and is a man-made inorganic fiber. Natural ores such as quartz sand, limestone, dolomite are used as main raw materials, and some chemical raw materials such as soda ash and borax are used to melt into glass. In the melted state, it is blown into floc fine fibers with the help of external force. In addition to maintaining the unique characteristics of heat preservation and heat insulation, it also has excellent fire prevention, shock absorption and sound absorption characteristics, which is conducive to reducing noise pollution and improving the working environment.

Abstract

The invention discloses a manufacturing method of a middle density fiberboard for enhancing the board soundproof effect. The middle density fiberboard comprises, by weight, 85 parts to 88 parts of wood fibers, 5 parts to 7 parts of glass wool, 7 parts to 9 parts of urea resin, 0.8 part to 1.2 parts of paraffin, 0.2 part to 0.3 part of caustic soda flakes, 0.2 part to 0.3 part of formic acid, 0.25 part to 0.3 part of ammonia chloride and 0.15 part to 0.2 part of melamine. The method has the beneficial effect that the soundproof effect of the middle density fiberboard can be improved, and the product added value is improved. The middle density fiberboard is mainly applied to high-grade decoration use of hotels, meeting rooms, labs and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method for enhancing the sound insulation effect of medium density boards. Background technique [0002] As a wood-based panel variety with excellent performance, wide application and high comprehensive utilization rate, MDF has good market expectations and development prospects. It is a board made of wood fiber as raw material, mechanically separated, applied with urea-formaldehyde resin or other synthetic resins, and then pressed by paving, molding, high temperature, heat conduction and other processes. The density and mechanical properties of medium density board are close to that of wood, and it is a kind of man-made board that is more popular in the world. The products can be widely used in medium / high-end furniture, audio musical instruments, vehicles, ships, construction and other industries. [0003] However, as the market's requirements for panels are ge...
