Description
Technical field
The present invention relates to a kind of tackiness agent, be specifically related to a kind of Modified Anion Polymerization SBS Block Copolymer Adhesives And Their Preparation Method.
Background technology
The SBS segmented copolymer is a kind of triblock copolymer of styrene-butadiene-styrene, has the dual nature of thermoplastic elastomer and vulcanized rubber concurrently.Anionic SBS block copolymer is used for tackiness agent and has advantages such as good springiness, good toughness, soltion viscosity are low, low temperature resistant, quick solidifying, and can make environmental-protection type adhesive, and very big market potential is arranged.
But, present SBS segmented copolymer, adhesive property is also relatively poor, can not satisfy the needs in relevant field.
Summary of the invention
The purpose of this invention is to provide a kind of inorganic whisker modified SBS segmented copolymer adhesive and preparation method thereof, to overcome the above-mentioned defective that prior art exists.
Inorganic whisker modified SBS segmented copolymer adhesive of the present invention is made of the component of following proportioning:

400～1200 milliliters of mixed solvents
The triblock copolymer of said SBS styrene-butadiene-styrene can adopt the commercially available prod, and the trade mark of producing as BaLing Petroleum Chemical Engineering Co., Ltd is the YH-768 product;
Anionic SBS block copolymer preferably;
Said terpine resin is the commercially available prod, and the trade mark of producing as the safe general chemical company limited in Ganzhou is the TP1095 product;
Said Gum Rosin is the commercially available prod, as the superfine rosin of level land board of oasis, Wuping County, Fujian Province woodsization company limited production;
Since the scientist of U.S. telephone bell company in 1948 finds whisker first, existing so far hundreds of whisker, mainly can be divided into inorganic crystal whisker and organic crystalline must two big classes.Described inorganic crystal whisker is meant and has certain length-to-diameter ratio that (general surpass＞10) and sectional area are less than 5.2 * 10
-5Cm
2A kind of whiskers body material, be a kind of by artificial control with the growth of monocrystalline form, shape be similar to staple fibre and size much smaller than staple fibre must the shape single crystal.Because the inner atomic arrangement structure that has high-sequential, its intensity be near the crystal theoretical value, thereby has extraordinary strengthening and toughening effect.
Preferably, inorganic crystal whisker can be selected from commercially available silicon carbide whisker, potassium titanate crystal whisker, calcium sulfate crystal whiskers, aluminium borate whisker, magnesium sulfate crystal whisker or ZnOw.
Described mixed solvent is 120
#The mixture of gasoline and acetone, in volume ratio:
120
#Gasoline: acetone=3～5: 1;
Preferably, the component by following proportioning constitutes:
SBS segmented copolymer 100 grams
Terpine resin 60 grams
Gum Rosin 60 grams
