Abstract
The present invention provides a kind of environment-friendly watertights to wash waterproofing agent and preparation method thereof, it is characterised in that the waterproofing agent includes a kind of hyper-branched polyester modifier, and molecular formula is：
Description
Technical field
The invention belongs to textile auxiliary's final finishing fields, and in particular to a kind of environment-friendly watertight washes waterproofing agent and its system
Preparation Method.
Background technology
The key subjects of in the 21st century, facing mankind environmental protection.All environmentally harmful products all can be slowly substituted.
At present, the leading products of fluorine-containing water-proof aagent are still that the acrylic polymer of the Long carbon chain containing perfluor is (general in the market
All it is the perfluoroalkyl acrylate containing 8 carbon).With progress of research, people gradually have found the acrylic acid of perfluor Long carbon chain
Containing perfluorooctane sulfonyl compound (PFOS) and perfluoro caprylic acid ammonium compounds (PFOA) in esters polymer, and both objects
Matter be difficult to degrade (PFOS/PFOA is considered as one of organic pollution for being most difficult to degradation), bioaccumulation and environmental toxicity compared with
Seriously.Animal experiments show that PFOS can have an impact heredity, reproduction, development, liver crucian carp, immune and angiocarpy etc..In addition also have
People points out that PFOS is possible to carcinogenic.Persistence, toxicity and the bioaccumulation that PFOS/PFOA in 2002 is considered in the environment be
The significant problem of threatening environment and human health.
In western developed country, some policies and regulations are promulgated in succession.European Parliament limited the quantity to related PFOS in 2006
Relevant regulations are done.To 2015, own completely forbid in the U.S. used PFOS/PFOA.Due to relevant limitation, develop a kind of new
, without PFOS/PFOA, and the good fabric waterproofing agent of waterproof effect oneself become research hotspot in recent years.Especially easily drop
Solution, water-fastness water-proof aagent will be as new developing direction.
Although the country puts into effect corresponding policies and regulations not yet, C8 main products are also using, international to limit the use of
Certain influence certainly will be also generated to domestic market with disabling, the waterproofing agent of short carbon chain (as long as using C6 as the product of representative)
Researching and developing and putting goods on the market has been trend of the times.Some international chemical industry major companies, have had launched C6 waterproofing agent products.In addition without
Harmless, the environmental-friendly no fluoro water proofing agent of poison is also another direction, oneself is released without fluoro water proofing agent for German Wa Ke companies, although nothing
The characteristics of effect of fluoro water proofing agent is slightly worse compared to fluorine-containing water repellent, water-wash resistance is not also strong, but its is environmental-friendly is that the latter can not
It is equal to, it is believed that in the near future, no fluoro water proofing agent will be main product.
Invention content
The purpose of the present invention is to provide a kind of waterproofing agent of environment-friendly type, there is excellent waterproof effect and water-fast simultaneously
Wash performance.
The present invention is to implement to realize by following technology：
A kind of environment-friendly watertight washes waterproofing agent, it is characterised in that and the waterproofing agent includes a kind of hyper-branched polyester modifier,
Its molecular formula is：
Wherein A-OH is trimethylolpropane and 2,2- dihydroxymethyls
Hyper-branched polyester prepared by propionic acid reaction, the hydroxyl value of x+y≤A, x:Y is 8.4-30.8：3.6-13.2.
The environment-friendly watertight washes waterproofing agent also comprising fibrillation plant fiber, the fibrillation plant fiber with it is hyperbranched
The mass ratio 1 of polyester modification object:2-5, the avarage fiber diameter of shown fibrillation plant fiber is 50-100nm..
The present invention also provides the preparation methods that environment-friendly watertight washes waterproofing agent, include the following steps：
(1) trimethylolpropane and 2,2- dihydromethyl propionic acids are pressed 1：9-1：41 molar ratio mixings, are warming up to 140-160
DEG C, argon gas protection is lower to add in mass fraction 0.5-1% catalyst p-methyl benzenesulfonic acids, and 400-500Pa is decompressed to after reacting 2-3h,
The reaction was continued 2-3h stops decompression and being cooled to 40-60 DEG C, adds in a certain amount of acetone solution, then precipitates to obtain product through ether and surpass
Branched polyester；
(2) by lysine diisocyanate and hydroxy-ethyl acrylate in molar ratio 1:1 mixing reacts 10- at 40-45 DEG C
12h obtains semi-additive product LDI-HEA.
(3) hyper-branched polyester, succinic anhydride and the acetone that secondly step 1 is obtained stir and evenly mix, and are reacted at 90-95 DEG C
4-5h is cooled to 45-50 DEG C of addition LDI-HEA, the reaction was continued 5-6h, stops reaction, and product is precipitated through acetone ether, and vacuum is done
It is dry to obtain product.
Further, trimethylolpropane described in step 1 and 2,2- dihydromethyl propionic acid press 1：20 molar ratio mixings.
Further, hyper-branched polyester, succinic anhydride and LDI-HEA molar ratios are 1 in step 3：8.4-30.8：3.6-
13.2
Further, hyper-branched polyester, succinic anhydride and LDI-HEA molar ratios 1：16.1：6.9.
A-OH is that trimethylolpropane reacts the hyper-branched polyester prepared with 2,2- dihydromethyl propionic acids.The hyperbranched poly
Ester constantly carries out hyperbranched reaction, constantly extends away, shape according to the branching agent 2 of addition, the content of 2- dihydromethyl propionic acids
Into hyperbranched macromolecular.One of specific example is as follows：
But A-OH is not limited to the example, can be using trimethylolpropane as
Centronucleus, hyper-branched polyester of 2, the 2- dihydromethyl propionic acids for the arbitrary extension degree of branched monomer.
The reaction mechanism of step 1 is as follows：
It wherein can be according to the difference of n, so as to constantly extend hyper-branched polyester.
The reaction mechanism of step 3 is as follows：
Wherein, the hydroxyl value of x+y≤A.
Beneficial effects of the present invention：
(1) present invention provides a kind of preparation method of modified ultra-branching object, distinctive multi-active base group and reticular structure,
Make the waterproofing agent that there is excellent waterproof effect and water-wash resistance.
(2) while in the waterproofing agent of the present invention fibrillation plant fiber of nanoscale can also be added, is had abundant
Surface area and active group, can be effectively dispersed in waterproofing agent and be combined with modified ultra-branching object, in fabric surface
It during effect, can more effectively attach on the surface of fabric fibre, form more firm waterproof layer and increase the residence time, from
And improve waterproof rate；
(3) present invention because in preparation process free-floride remove fluorine-containing water repellent from and bring the harm such as PFOS/PFOA, while prepared
Also the harmful substances such as formaldehydeless are a waterproofing agents of new generation with environment-friendly advantage in journey and final finished.
