1.5 parts of auxiliary agent, 19 parts of cation butadienestyrene copolymer emulsion, cationic styrene-acrylate copolymer emulsion 26
Part, it is flexible more preferable the advantages of.
Embodiment
First, to part material
Do following introduction：
Cationic styrene-acrylate copolymer emulsion, market are on sale, it is desirable to which glass transition temperature is -10 degree, and viscosity is
800mPa.s, solid content are 57% or so, and MFT is -20 °.
Pitch：Pitch is a kind of product of crude oil processing, be at normal temperatures black or dark brown sticky liquid,
Semi-solid or solid, mainly contains the hydro carbons for dissolving in chloroform and nonhydrocarbon analog derivative, its property and composition with crude oil origin and
Production method difference and change.The key component of pitch is oil, resin and asphalt matter.Also containing 2% ~ 3% bitumencarb and
Like carbon thing, also contain wax.Oil and resin in pitch can infiltrate asphalitine.The structure of pitch is inhaled using asphalt matter as core
Attached part resin and oil, form micelle.
Cation butadienestyrene copolymer emulsion：Styrene-butadiene emulsion is to be copolymerized by butadiene and styrene emulsion and obtained,
Abbreviation SBRL.Relative density 0.9~1.05.Combinated styrene content amount is 23%~85%, the styrene-butadiene emulsion combination benzene second largely produced
Alkene amount is 23%~25%, and high-phenylethylene emulsion (SBR-HSL) combinated styrene content amount is then up to 80%~85%.Conventional method is made
Styrene-butadiene emulsion total solid content be 40%~50%, and high solid emulsion total solid content is then 63%~69%.
Cationic emulsifier：Cationic emulsifier refers to a kind of emulsifying agent with cation group.Cationic emulsifier
It can be used for producing positively charged polymer emulsion, this emulsion can be used for impregnating fabric.Because fabric is often negatively charged, it is right
There is repulsive interaction in negatively charged emulsion particle.When such as impregnating fabric with anionic emulsion, the result that cannot just get well.It is actual
On, the application of cation emulsion is not too much extensive, and the work of this respect at present is made also less, but due to cationic emulsifier not
The features such as being afraid of hard water and applying in acid condition, therefore its purposes has the trend expanded day by day.
PH conditioning agents are also known as acidity regulator to maintain or change the material of food acid-base value.Fermentation acid plus alkali face
It is exactly acidity regulator.It is mainly controlling acidulant needed for food, alkaline agent and salt with cushioning effect.It is every kind of
It is different with sour feature that acidity regulator tart flavour is slight, and used herein is AMP-95 auxiliary agents, and market is on sale.
Defoamer：Defoamer, also referred to as defomaing agent, it is that surface tension is reduced in food processing process, suppresses foam and produce
Or eliminating that to have produced the food additives of foam be conventional substances, there is sale market.
With reference to embodiment, the invention will be further described.
