Description
Technical field
The invention belongs to the technical fields of decorative wall cloth, and in particular to a kind of waterproof wall cloth and preparation for interior decoration
Method.
Background technology
Someone says jokingly that wallpaper, wall paper are metope " fashionable dresses ", and this point also draws it mild, because of its often generation as fashionable dress
The trend in table epoch reflects the individual character of people, and expression people are to beautiful and comfortable pursuit.In the common of designer and technologists
Under innovation, using new technology and equipment, existing wallpaper, wall paper product have had that style is abundant, riotous with colour, skin texture is fresh
It is bright, texture is soft, sound-absorbing is breathed freely, be not easy to burst, mount is simple, replaces the advantages that being easy and can wash by water etc., and be made
The environmental protection such as fire-retardant, heat-insulated, heat preservation, sound-absorbing, sound insulation, antibacterial, mould proof, Water-proof and oil-proof, antifouling, dust-proof, antistatic it is multi-functional
Polymerization product.The decorative major embodiment of wall paper is culture, and what functional aspect embodied is then that multi-functional polymerization is showed
Safety and environmental protection, energy-saving low-carbon.The color of wall paper, pattern, texture can more adapt to various environment by well-designed
Need and meet each level Modern human populations aesthetic conceptions, to build luxurious, warm, comfortable, healthy environment for people,
This is that other decorative material for wall surface are incomparable.
Wall paper is material very common in existing interior decoration, is all suitable in many places, mainly by gluing and
The mode of splicing is set on wall, although the quality of existing wall paper is more excellent, there are still have shortcoming：It is easier to
Discoloration scrubbing resistance, the easy moisture absorption and is not gone mouldy, and especially effect is poor in terms of its waterproof.Due to above-mentioned defect, greatly limit
Popularization of the decoration in decoration, in order to wallpaper industry brings great industry obstacle.
The wall paper of wide cut often uses in the medium-to-high grade place such as hotel lobby, meeting room, large-scale restaurant, for waterproof, prevents
It is oily, mould proof to have very high requirement, thus wide cut wall paper often over three proofings processing, and the wall paper Jing Guo water-proofing treatment how
Ink is fully absorbed and fixed during digit printing and forms a new problem again, such as number of patent application is
It is multiple respectively to set one layer of waterproof in the tow sides of wall paper for a kind of waterproof wall cloth that 201210567415.8 patent document is announced
Layer is closed, is measured by the multiple processing experiment of applicant, structure so can play certain waterproof oil-proof result really, but exist
Two drawbacks：One, two layers of waterproof composite layer can hinder absorption of the wall paper to printing ink, color development effect in the link of dyeing and printing process
Fruit is bad, two, such waterproofing design simultaneously can also so that gas permeability is bad, holds if cannot breathing freely for wall paper
Easy mould growth, it is mouldy.
Chinese invention patent application number 201610418194.6 discloses a kind of ornamental direct paste composition wall paper
Production method, which provides a kind of production method of ornamental direct paste composition wall paper, the method, including prepares quiet
Electric flocked fabric, functional topical finishing.Combination wall paper prepared by the present invention, 2~4mm of thickness, 1.5~2m of breadth, system of the present invention
Standby combination wall paper, firmness are high, convenient and efficient, and decoration is with being not easy to be worn；Abrasion resistance taber1000~5000 time are not
It is damaged；Martindale's abrasion resistance 6~80,000 time；Wall paper prepared by the present invention, dry fastness, fastness to wet rubbing, solvent rub
Fastness, color fastness to water, color fastness to light are 3~5 grades；Combination wall paper prepared by the present invention, not easily to fall off, separation strength 10N
More than；Combination wall paper prepared by the invention, environmental protection, content of formaldehyde is low, and content of formaldehyde is less than 20ppm, after being used for interior decoration, first
Aldehyde ＜ 0.07mg/m3, free from extraneous odour.
Chinese invention patent application number 201710722113.6 discloses seamless composite water-proof wall paper and preparation method thereof, should
A kind of seamless composite water-proof wall paper of disclosure of the invention and preparation method thereof, this is seamless composite water-proof wall paper includes from top to bottom successively
Compound nonwoven layer, adhesive layer, the surface of adhesive layer is implanted with staple fiber；Wherein, adhesive layer is dried by adhesive, is glued
Mixture by styrene-acrylic emulsion, sodium metasilicate, chlorination ethylene propylene diene rubber, polysiloxanes, polyacrylamide, nanometer calcium, nano diatomite,
Sodium phosphate, mica powder, water, thickener and antifoaming agent composition；The length of staple fiber is 35-50mm.It is made by preparation method
The seamless composite water-proof wall paper have excellent mechanical property and waterproof effect.
When current preparation waterproof wall cloth, it is the porous, expanded films of PTFE that the overwhelming majority, which uses, although its hydrophobic performance is excellent
It is different, but it is expensive, and there are contradictions between cost, with consumer；In addition, foaming preparation section is cumbersome, PTFE fusing points
Height, foaming are not easy, and increase technology difficulty.
Invention content
In view of the deficiencies of the prior art, the present invention proposes that a kind of air permeability effect is good, at low cost, is not easy mouldy one kind and is used for
The waterproof wall cloth and preparation method of interior decoration.
To solve the above problems, the present invention uses following technical scheme：
A kind of waterproof wall cloth for interior decoration, the waterproof wall cloth are by modification of nylon nonwoven layer, the netted hot melt of high tenacity
