Description
Technical field
The invention belongs to the latex product field of containing polymer substance, relate in particular to emulsified paraffin wax damp-proof agent for mineral wool sound absorption board.
Background technology
Mineral wool sound absorption board is the widely used a kind of high-grade functional ornamentation sound-absorbing material of present domestic construction decoration industry, and it is that main body is aided with multiple other material and auxiliary agent is made with the mineral wool.This material also must have good humidity resistance except the basic function that should have sound absorption and decorate, so that can keep its inherent form and small amount of deflection to change under changeable climate and different humidity.The auxiliary agent of giving the good moistureproofness of acoustic board is called non-blushing thinner, and this non-blushing thinner should have reliable stability, not breakdown of emulsion, never degenerate, so that the turnover of commodity and use; It should be an emulsion state also, is convenient to can mix uniformly in the making of acoustic board in the slurrying pond, forms uniform dispersion state with mineral wool and other ancillary component.Not having polar group in the molecular structure of paraffin, is a kind of apolar substance, has good moistureproofness, but paraffin is difficult to the emulsion that high stability is made in emulsification, has limited its use.Up to now, the method for making that does not have the ideal emulsified paraffin wax damp-proof agent for mineral wool sound absorption board.Present employed non-blushing thinner is with the material heat fused of paraffin and stearic acid, adds nonionic surface active agent then, as alkaline matters such as fatty alcohol-polyoxyethylene ether and aqueous sodium hydroxide solution, ammoniacal liquor, makes after stirring." oil and gas chemical industry ", the second phase the 27th in 1998 volume has been published article " preparation research of the small emulsion of paraffin ", adopt energy-saving phase emulsion process, the selection by emulsifying agent and assistant for emulsifying agent and composite has made the small emulsion of paraffin, be used for glue used in paper-making, respond well.But, the present following shortcoming of paraffin wax damp-proof agent ubiquity:
1, is difficult to make stable emulsion, demulsifying phenomenon takes place easily, separate out paraffin and go bad.
2, the mineral wool of polar group that shortage is necessary in the non-blushing thinner and acoustic board and other composition is intermolecular with the Van der Waals force combination, and non-blushing thinner is difficult to effectively and uniform absorption, and moisture effect is poor.
3, mineral wool sound absorption board complete processing difficulty, because the separating out of paraffin, when slurries online making sheet, mesh is easily blocked by paraffin, needs often to shut down cleaning or more renew net.
4, the acoustic board poor performance of Zhi Zuoing, at the baking stage of making sheet, because paraffin is failed effective combination, high volatility under the high temperature, paraffin is overflowed easily, causes disaster hidden-trouble.
Summary of the invention
The purpose of this invention is to provide a kind of emulsified paraffin wax damp-proof agent for mineral wool sound absorption board, high stability that it has and good humidity resistance have effectively solved the defective that paraffin is easily separated out in the prior art.
Another object of the present invention provides a kind of preparation method of emulsified paraffin wax damp-proof agent for mineral wool sound absorption board of the present invention.
