Description
Technical field
The invention belongs to new function material technical fields, and in particular to a kind of to reduce free formaldehyde content in impregnated paper
Absorption cleaning agent.
Background technique
Impregnated paper is a kind of plain color paper or printed decoration paper by impregnating resin, and dry to obtaining afterwards to a certain degree
, the bond paper with certain resin content and volatile content is glued with artificial board substrate after hot pressing.Impregnated paper and its
Its surface decoration material compares, and has operating procedure simple, and surface property is excellent, and surface detail is beautiful, cheap, resistance to height
The advantages that warm.Phenol glue water retting paper is a kind of decorative paper impregnated through phenolic resin, for improving the surface property of wood-based plate,
It has been widely used in building plain form industry.PSF can generate self-curing under high temperature, condition of high voltage, be used in hardwood,
Plate and cork clad can with bottom paper.Advantage has: widely used-PSF serves many purposes, and is such as used for cement formwork, vehicle
Compartment bottom plate, container, cabinet, storage shelf and bin etc.；Acidproof, alkaline-resisting, the resistance to organic chemicals of persistence-PSF, resistance to neutrality
And ackd salt, therefore substantially increase the number of turnover of cement formwork；Outdoor application-PSF overlaid wood based panel weatherability is good,
It is handled without finishing；Visual effect-can cover the random defect of substrate, and form uniform solid object surface；Processing
Property-sawing, fluting, drilling property it is good, the breakage and chipping of veneer can be reduced.
As the step of urban construction is accelerated, ornament materials has obtained faster development, and impregnated paper industry is due to starting point
Lower, currently, professional is few in industry, so that industry development level is uneven, product quality cannot be ensured.Impregnated paper is in life
The release that the greatest problem faced in use process is exactly pernicious gas is produced, particularly pertinent is that content of formaldehyde is exceeded.This is to ring
Border and human body cause great harm.And solution is mostly by controlling synthetic ratio at present, optimized production process uses envelope
That closes material prevention formaldehyde is released to major way, and can not have the function that thorough absorption cleaning, still can be in the later period
Free formaldehyde is continually released, interior is entered, is done harm to huamn body.
Summary of the invention
