But because in the process of manufacturing paper with pulp, functional fibre has significant proportion at the fire retardant nonwoven fabric substrate surface, and the wallpaper profile is not attractive in appearance, easily bubbling, alice, take off seam, the problem such as be difficult for peeling off.
Summary of the invention
The objective of the invention is in order to solve traditional wallpaper profile not attractive in appearance, easily bubbling, alice, take off seam, the problem such as be difficult for peeling off, and a kind of fire-retardant non-woven paper and preparation method thereof is provided, this kind non-woven paper can anti-water, good looking appearance after the mildew-resistant, anti-wiping, good processability, coating.
The technical solution used in the present invention is:
A kind of fire-retardant non-woven paper, it is made by the raw material of following weight part ratio: fibre stuff 70-99 part, adhesive 1-30 part; Wherein fibre stuff comprises wood pulp fibre and functional fibre, and the wood pulp fibre quality accounts for 0%-95%, and the functional fibre quality accounts for 5%-100%.
Described functional fibre is hydrophilic fibre, non-hydrophilic fibre or both mixing.When described functional fibre was hydrophilic fibre, the functional fibre mass content preferred 10～50% in the fibre stuff.When described functional fibre was non-hydrophilic fibre, the functional fibre mass content preferred 10～70% in the fibre stuff.
The preferred wood pulp fibre quality of fibre stuff accounts for 70～90%, and the functional fibre quality accounts for 10～30%.
Described hydrophilic fibre is selected from one or more among collagenous fibres, keratin fiber, fibroin fiber, regenerated celulose fibre and the Azlon; Described non-hydrophilic fibre is selected from one or more in synthetic fiber and the inorfil.
Described keratin fiber is wool, and described regenerated celulose fibre is viscose, copper ammonia fibre or acetic ester fiber, and described azlon is casein fibre, Zein fibers, ground nut fiber or soybean fiber.
Described synthetic fiber are the wrong fiber of cyclization, polypropylene fibre, polyethylene fiber, polyvinyl acetal fiber, polyvinyl chloride fibre, politef fiber, polyester fiber, polyamide fiber, polyurethane elastomeric fiber, aramid fiber 1313, polyamide fiber, polyphenyl and miaow or polyhenylene three nitrine fibers.
Described inorfil is carbon fiber, glass fibre.
It is 0.67-25D that described functional fibre has a kind of its fineness at least, and length is 2mm-35mm.
Described functional fibre preferably contains one or more in the carbon fiber, glass fibre, aramid fiber 1313 of mass content 1%-90%.
Described adhesive can comprise one or more of natural glue and synthetic adhesive.Natural glue is shellac, gelatinized corn starch, specimens of one's blood or natural rubber adhesive; Synthetic adhesive is the agent of thermosetting resin gluing, thermoplastic resin adhesives, rubber adhesive or inorganic adhesive.The agent of thermosetting resin gluing comprises one or more in ethene and so on, esters of acrylic acid, phenylethylene, cellulose family, the alkyd resins class; The rubber adhesive comprises one or more in reclaimed rubber, butadiene-styrene rubber, neoprene, cyano group rubber, butyl rubber, silicon rubber, the polyurethane rubber.
Described adhesive preferably adopts polyvinyl alcohol, starch and Cypres, and by solution oven dry weight polyvinyl alcohol: starch: Cypres is 2～8:0.04～0.15:0.8.
The used adhesive consumption of the present invention is decided on the requirement of strength of paper, generally between 1-10%, the intensity that is lower than 1% paper can be not, be higher than 10%, the intensity of paper is high, but the microcellular structure of paper is blocked, and affects the permeability of paper, and the deflection of paper is too high, is unfavorable for processing and the use of follow-up workshop section.
In order further to increase the water repelling property of wallpaper, when on-line coater, also can add Cypres, the consumption of Cypres is lower than 0.5% generally at the 0.5-10% of adhesive consumption, and sizing efficiency is not obvious.Be higher than 5%, the surface of paper has soapy feeling, is unfavorable for the processing of follow-up workshop section.
The preparation method of above-mentioned fire-retardant non-woven paper, step is as follows: after functional fibre, wood pulp fibre, water are added the pulper mix and blend, pull an oar by mill, add and fill out the pond and add and fill out auxiliary agent and filler (routine), through copying forebay, stock proportioner, enter the head box online, dehydration, squeezing, oven dry, on-line coater, enter oven drying, cylinder dried, coil paper, rewinding, machine is coated with outward, and rewinding is finished paper.The outer coating process of machine: coating fluid prepares → selects bodystock paper → coating machine coating → drying → press polish or surface dressing → rewinding.The coating fluid weight part ratio forms preferred: coarse whiting 50-100 part, china clay 20-30 part, water 40-60 part, CMC 1-2 part, dispersant 1-2 part, lubricant 1-3 part, water repellent agent 1-2 part, latex 35-45 part.
Fire resistance will reach the B level technical requirement among the GB8624-2006 " construction material and goods classification system for fire performance ".

The invention has the beneficial effects as follows:
Functional fibre is owing to its smooth surface, and the tightness of non-woven fabrics base material is all lower, and behind the adding functional fibre, the tightness of paper reduces in raw material, and elasticity increases, and makes nonwoven fire retardant base material in process, and its shrinkage phenomenon disappears.The water absorbent surface performance of chemical fibre is far below wood pulp fibre, and wood pulp fibre generally can absorb and be equivalent to 9 times water, and the regain of chemical fibre is all below 5%, and such as polyvinyl chloride fibre, the regain of the fibers such as polypropylene fibre is zero especially.Under the equal tightness like this, the fire retardant nonwoven fabric base material that adds functional fibre has just had the raising of matter than the WATER RESISTANCE that entirely is the paper of pure wood pulp.
The adding fineness is 0.67-25D, and length is the functional fibre of 2-35mm, owing to have functional fibre at the nonwoven fire retardant substrate surface that makes of manufacturing paper with pulp, then nonwoven fire retardant base material is after coating, the surface of fire retardant can show naturally striped, and good looking appearance does not need to process in addition.
Generally between 5～100%, when the functional fibre addition was less than 5%, the characteristics of functional fibre were not reflected the addition of functional fibre, the amount that different fibers adds is differentiated, some fiber is fully not hydrophilic, after addition is many, and the difficult of manufacturing paper with pulp and will become; And the picture viscose is owing to itself get by wood pulps spray silk, and its regain is than textile also height, even 100% use, it is also out of question to manufacture paper with pulp.
The surface of the fire-retardant non-woven paper of the present invention can show naturally striped, and good looking appearance does not need other processing.Simultaneously, the fire retardant nonwoven fabric product does not shrink when process, the free from dampness sense, and it is complete to take off paper, and the pliability of paper is very good.Do not burn under flame, do not have flame, surpassing more than 400 degree only is carbonization, and therefore, this product has good fire resistance.
