Description
Technical field
The present invention relates to non-woven fabrics field, a kind of preparation of the water-fast nonwoven cloth with epoxy coating is specifically referred to
Method.
Background technology
Due to cheap, the ceiling of waterproof, rain cover, but plastics are typically done in people's custom using Colored plastic film
Thin film strength is too low, easily scratches, and sunshade is bad, and impermeable cloth has just been invented later and has come waterproof, rain cover, jail
Gu it is durable.The cloth species with water-proof function is many in market, although the good water-proof effect of Partial Species, but pliability
Difference, gas permeability is bad, lacks oil rub resistance ability.
And it is more using coated fabric in existing technical scheme, described coated fabric is a kind of textile, and coating is sticked
Condensation material is formed in situ single or multiple lift coating in fabric one side or positive and negative two sides.It is made up of the material of two layers or more than two layers,
It is textile that wherein at least, which has one layer, and another layer is totally continuous polymer coating.And in past ten years, coating is knitted
Thing production there occurs great changes.Today, due to using production tech, as the base fabric of coated fabric, away from bafta
Old concept.Coating variety rolls up, including with grease proofing, ultra-violet radiation resisting, fire prevention and chemical resistance erosion performance etc.
A series of new polymer.The method that textile constructions, coating polymer and coating design etc. generally determine coating.In coating skill
Art is updated emerged in large numbers with a collection of new coating apparatus in the case of, the process velocity and product quality of coated fabric occur therewith.
But the coated fabric of prior art can not have preferable water resistance and anti-uv-ray, and long-term out of doors using easy
Aging, simply the problems such as fabric face coating shedding, and the intensity of general coated fabric is not high, can go out after long-time use
Now tear the phenomenon of broken hole.
The content of the invention
It is an object of the invention to provide one kind with epoxy resin, with preferable waterproof water resistance, by reasonable
Set and reach higher-strength and the also preparation method of the multiple field cloth with the anti-aging function of preferable antiultraviolet.
The present invention is achieved through the following technical solutions：A kind of preparation side of the water-fast nonwoven cloth with epoxy coating
Method, the step is：
（1）It is prepared by waterproof matrix：The Hydromethyl bisphenol Resin material needed for waterproof matrix is prepared, and in methylol bisphenol-A
It is stand-by added with toughener carboxyl LNBR formation waterproof matrix in epoxide resin material；
（2）It is prepared by fabric glue：Represented with parts by weight, take 100 parts of ethylene-vinyl acetate copolymer, 40 parts of butyl rubbers, 35
The butylphenol resin of part, 9 parts of dibutyl phthalate and 5 parts of calcium carbonate, and prepare fabric glue using raw material
It is stand-by；
（3）It is prepared by non-woven fabrics：It is 38 according to mass ratio：62 take polytetrafluoroethylene fibre polymer and poly- paraphenylene terephthalamide couple
Non-woven fabrics is made in fibers polymer, then blending, and will be stand-by;
（4）It is prepared by basic unit：Ready non-woven fabrics is first placed on orlop, ready fabric glue is then uniformly laid,
Fabric glue waterborne pavement at least one layer specification is the alkali-free glass fiber cloth of CNP50-5 × 5, and is re-layed in alkali-free glass fiber cloth upper surface
One layer of fabric glue, finally topmost fabric glue waterborne pavement layer of non-woven fabric and hot pressing into double-deck non-woven substrate；
（5）The basic unit prepared is put into the septichen phenyl ester solution that temperature is 62-66 DEG C and stands 12-16min, so
Basic unit and room temperature 30min is taken out afterwards to form UV-absorbing layer；
（6）Finally ready waterproof matrix is uniformly applied to outside basic unit and secondary hot pressing is carried out, it is final to cut under shaping
Line, forms final cloth product.
Further, the step（1）The preparation process of middle Hydromethyl bisphenol Resin material is：
（1.1）It is raw material to take sodium hydroxide, epoxychloropropane, methylol bisphenol-A and methyl iso-butyl ketone (MIBK), and by a certain percentage
Add in reactor, then 50-60 DEG C of water bath with thermostatic control and stir；Then condensing reflux reacts 24h；
（1.2）Then add after water is sufficiently mixed and staticly settle after question response terminates, by residue after then upper aqueous layer is filtered out
Solution is heated to 69 DEG C and adds sodium hydroxide solution, then constant temperature stirring reaction 1.5-3h；
（1.3）Distilled water washing point liquid is added after question response, until when the water layer pH value separated is neutral, filtrate is completely distilled off
Later, light yellow, transparent Hydromethyl bisphenol Resin is obtained.
Further, the step（2）It is middle to prepare concretely comprising the following steps for fabric glue：At a temperature of 64-72 DEG C to ethene-
Butyl rubber is added in vinyl acetate copolymer, and stirs 30min, then thereto sequentially add synthesis butylphenol resin and
Calcium carbonate, then stirs 1-2h, is eventually adding dibutyl phthalate and stirs 15-20min, so as to form fabric glue.
Further, the step（4）And step（7）Middle heat pressing process carries out hot pressing using Three roller pressing device.
Further, the step（3）Prepared by middle non-woven fabrics concretely comprises the following steps：
（3.1）First polytetrafluoroethylene fibre polymer and Fanglun 1414's polymer are extruded and drawn respectively
Stretch, untill each self-forming continuous filament yarn；
（3.2）Then polytetrafluoroethylfiber fiber filaments and PPTA polymer are laid into networking, and entered
Precompressed is carried out in pressure roller；
（3.3）Then web feeding milling train hot rolling, so as to form non-woven fabrics by way of its own bonding and heat bonding.
The two ends of the macromolecular of bisphenol A type epoxy resin are that have many on respond very strong epoxy radicals, molecular backbone
Ehter bond, is to occur many secondary hydroxyls regularly, apart from each otherly on a kind of larger molecular resin chain of linear polyether structure n values
Base, can regard a kind of long-chain polyhydric alcohol as, and also have a large amount of phenyl ring, methine and isopropyl on main chain, epoxy radicals and hydroxyl
Resin reaction is assigned, makes resin cured matter with very strong cohesive force and bonding force；Ehter bond and hydroxyl are polar groups, are helped
In raising wellability and adhesion；Ehter bond and C-C keys make macromolecular have compliance；Phenyl ring imparting polymer is with heat resistance and just
Property；Isopropyl support group reduces intermolecular force, assigns the certain toughness of resin；The bond energy of-C-O- keys is high, so as to improve alkaline-resisting
Property.
And elongation is low after epoxy resin cure, fragility is larger, is easy to crack when external force is born in bonding site,
And extend rapidly, cause glue-line to ftracture, not endurance, it is impossible to be used as structural bond.Therefore, it is necessary to try to reduce fragility,
Increase toughness, improve bearing strength.It is all to lower fragility, increase toughness, and do not influence the thing of other main performances of adhesive
Matter is toughener.Rubber-like toughener and thermoplastic elastomer (TPE) class toughener can be divided into.And described septichen benzene
Ester is a kind of ultra-violet absorber, and for plastic products, but absorbing wavelength scope is narrower.Food and Drug Administration's approval is used
In the acrylic resin articles for use of contact food.
The present invention compared with prior art, with advantages below and beneficial effect：
The method of the present invention by rationally controlling each reactant between proportioning, rationally control reaction condition and prepare a kind of suitable
Water-fast nonwoven cloth with epoxy coating, epoxy resin composition that waterproof matrix of the invention is obtained and obtain
Solidfied material, with the mechanical properties such as moisture-proof, excellent heat resistance, and impact resistance also excellent performance, adhesive property is good,
Excellent in durability, and preparation method is simple and easy to apply, is adapted to industrialized production, and added with a certain amount of ultra-violet absorber energy
Enough improve ability and ultraviolet resistance.
