Problems solved by technology

Chinese patent document CN 2350456Y discloses "a kind of sound insulation board", which can achieve sound insulation effect, but its fireproof performance is poor, which limits its application range
However, due to the existence of pores, the mechanical strength of the plate will be greatly reduced, and it is difficult to use it as some high-strength support structures.
Publication number CN201877680U discloses "isolating switch insulating board", which can be used for insulating switch parts such as electrical equipment, but it does not have sound insulation, corrosion resistance and other properties, and its application field is limited

Abstract

The invention relates to a method for manufacturing an unsaturated polyester resin reinforced glass bead plate. The method comprises the following steps of: 1, pouring an unsaturated polyester resin and a low shrinkage additive into a glue blending tank, stirring uniformly, adding a polymerization inhibitor, a release agent, a curing agent and a viscosity reducer, stirring uniformly, adding hollow glass microspheres and aluminum hydroxide, stirring uniformly, adding a thickening agent, and stirring uniformly to obtain unsaturated polyester resin paste; 2, coating the unsaturated polyester resin paste on the surfaces of a glass fiber mat or a glass fiber three-dimensional fabric, and coating by using polyester (PET) carrier films to obtain a prepreg; 3, drying the prepreg obtained in the step 2 in a drying room at the temperature of between 30 and 50DEG C for 12 to 24 hours; 4, removing the PET carrier films after the prepreg is dried, and cutting the prepreg; and 5, pressing a piece of prepreg in a hot-pressing mold, or overlapping a plurality of pieces of prepregs, and pressing the overlapped prepregs in the hot-pressing mold to obtain the unsaturated polyester resin reinforced glass bead plate.

Description

technical field [0001] The invention belongs to the technical field of manufacturing flame-retardant sound-insulating insulating boards, and in particular relates to a manufacturing method of unsaturated polyester fiber-reinforced glass bead boards. Background technique [0002] At present, sound insulation panels are required in many occasions, such as cinemas, hotels, highway sound-reducing noise-reducing walls and many other public places. After retrieval, the Chinese patent literature discloses some technical proposals related to the sound insulation board. For example: Chinese patent document CN 1070024A discloses a "sandwich heat preservation and sound insulation structural part of double-layer reinforced concrete slab and light concrete web". Although the sound insulation board of this technical solution has a certain sound insulation effect, the overall structure is heavy and The scope of application is narrow. Chinese patent document CN 2350456Y discloses "a sound...
