Description
Technical field
The present invention relates to non-woven fabrics field, a kind of preparation method of the sunshade cloth of high intensity antiultraviolet is specifically referred to.
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 higher-strength is reached by rationally setting and also with preferable antiultraviolet
The preparation method of the puggaree cloth of anti-aging function.
The present invention is achieved through the following technical solutions：A kind of preparation method of the sunshade cloth of high intensity antiultraviolet, institute

Paraffin, 56 parts of water-soluble polyethylene ethylene glycol wax, 12 parts of BHT and 6 parts of barium sulfate, and utilize
It is stand-by that raw material prepare fabric glue；
（3）It is prepared by non-woven fabrics：It is 31 according to mass ratio：69 polymerize to take polyimide fiber polymer and polypropylene fibre
Non-woven fabrics is made in thing, 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 medium-alkali glass fiber cloth of CNP145-4 × 4, and is repaved in medium-alkali glass fiber cloth upper surface
If one layer of fabric glue, finally topmost fabric glue waterborne pavement layer of non-woven fabric and hot pressing into double-deck nonwoven fabric base
Layer；
（5）The basic unit prepared is put into the 2,4-DihydroxyBenzophenone solution that temperature is 72-76 DEG C and stands 15-20min,
Then take out basic unit and room temperature 45min is 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 brominated bisphenol S epoxide resin materials is：
（1.1）It is raw material to take sodium hydroxide, epoxychloropropane, brominated bisphenol S and methyl iso-butyl ketone (MIBK), and is added by a certain percentage
Enter in reactor, then 60-63 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 2.5-3h；
（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 brominated bisphenol S epoxy resin is obtained.
Further, the step（2）It is middle to prepare concretely comprising the following steps for fabric glue：To ethene at a temperature of 72-75 DEG C
Paraffin is added in base pyrrolidones-vinyl acetate copolymer, and stirs 30min, synthesizing water-solubility is then sequentially added thereto
Polyethylene glycol wax and barium sulfate, then stir 1-2h, are eventually adding BHT and stir 15-20min,
So as to form fabric glue.
Further, the step（4）And step（7）Middle heat pressing process carries out hot pressing using five roller press.
Further, the step（3）Prepared by middle non-woven fabrics concretely comprises the following steps：
（3.1）First polyimide fiber polymer and polypropylene fibre polymer are extruded and stretched respectively, until each self-forming
Untill continuous filament yarn；
（3.2）Then polyimide fiber long filament and polyacrylic polymer are laid in networking, and entrance pressure roller and carries out precompressed；
（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 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
