Problems solved by technology

[0002] As we all know, ceilings are widely used in the architectural decoration industry to decorate the top surface of buildings; the ceilings currently on the market are made of gypsum or metal materials. For gypsum materials, their sound absorption effect is not good and they are fragile; while metal The material also has the problem of sound absorption effect, and it is also very heavy; therefore, the traditional ceiling will have the defect of inconvenient use in the actual use process

Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific examples.

[0009] In terms of weight percentage, different proportions of hot-melt fiber and short-fiber flame-retardant polyester fiber are selected for mixing. Generally, the melting point of the hot-melt fiber is about 130°C, and the melting point of short-fiber flame-retardant polyester fiber is about 260°C. The fibers are mixed and then loosened by a carding machine, and then spread to a cotton net with a certain height, about 200g / m2, by a needle punching machine, and then sent to a set temperature of 150 ° C ~ 200 ° C Heating in the oven for about 3 minutes, making full use of the characteristics of the different melting points of the two fibers, making the hot-melt fiber fully melt and stick to the polyester fiber, effectively increasing its strength and hardness, and finally ironing by ironing equipment to form a ceiling. Therefore, there is no need to use the method of coating ...

Abstract

The present invention relates to process of making ceiling board. The process includes the steps of mixing meldable fiber and fireproof short Dacron fiber, opening in a carding machine, spreading with one mesh placing unit to form web of certain thickness, needling with a needling machine, stoving in a stove at 150-200 deg.c for about 3 min for melting the meldable fiber and adhering to the Dacron fiber, and final ironing to obtain flat ceiling board. The produced ceiling board has high sound absorbing effect, high strength and high hardness, no formaldehyde release and environment friendship.

Description

technical field [0001] The invention relates to a ceiling manufacturing method, in particular to a ceiling manufacturing method with high strength, hardness, sound absorption and environmental protection effects. Background technique [0002] As we all know, ceilings are widely used in the architectural decoration industry to decorate the top surface of buildings; the ceilings currently on the market are made of gypsum or metal materials. For gypsum materials, their sound absorption effect is not good and they are fragile; while metal The material also has the problem of sound absorption and is particularly heavy; therefore, the traditional ceiling has the disadvantage of being inconvenient to use in actual use. Contents of the invention [0003] The main purpose of the present invention is to provide a method for manufacturing a ceiling, which can effectively manufacture a ceiling with high strength and hardness, sound absorption and environmental protection. [0004] To...
