Description
Technical field
It is new compound that the application with PB Polybutene-1 (PB-1) and trans-polyisoprene (TPI) is that main material is prepared for
Material, this composite can be used for preparing PB-1 floor heating pipe joint materials.The advantages of joint material is：Using tradition heat
While fusion welding, material has pyrocondensation performance, the attachment force of increase joint material and matrix tubing, improves material in joint
Compressive resistance.
Background technology
Plastic tube is using plastic resin as primary raw material mostly, adds the auxiliary agents such as stabilizer, lubricant, using extrusion molding
The products similar obtained etc. processing method.Because it has the spy such as light, corrosion-resistant, good appearance, handling ease, easy for construction
Point, more and more extensive application is obtained in architectural engineering.It is mainly used as tap water supply system pipe arrangement, the row of building construction
Water, exhaust and blowdown sanitary pipe, subsoil drain system, rain pipe and electric wire install matched penetration pipe etc..
Plastic tube has thermoplastic pipes and the major class of thermosetting plastics pipe two.Wherein, what thermoplastic pipes used is main
Resin has Corvic (PVC), polyvinyl resin (PE), acrylic resin (PP), polystyrene resin (PS), propylene
Nitrile-butadiene styrene resin (ABS), PB Polybutene-1 resin (PB-1) etc..PB-1 resins are the high inertia synthesized by butene-1
Polymeric material, there is very high chemical stability, there is good abrasion resistance, anti-fissility, heat-resisting quantity, low temperature resistant
Performance, shock resistance is good, is easily bent without rebounding, is most soft in several ground heating pipes.In numerous tubing, PB-1
Tubing is almost classic pressure resistant pipe material, its long-term use of circumference stress ability to bear highest.Therefore, PB-1 tubing is current
One of state-of-the-art running water pipe, hot water and heating comb in the world, non-corrosive, not burn into non-scaling, long lifespan are (up to 50-
100 years), and ageing-resistant, creep resistance excellent performance, it is one of ideal material as heating coil, there is " the Huang in plastics
The reputation of gold ".
The connection generally use sweat soldering of traditional thermoplastic pipe, electric fusion welding, the methods of mechanically connecting, are realized.It is poly-
Butene-1 pipe uses universally acknowledged safe connection mode-hot-melt adhesive paste.The leakage of pipeline mostly occurs on connector, therefore,
Rational pipe fitting joint formula is particularly important to the pipe fitting joint product of excellent performance.
The content of the invention
During tube material sweat soldering, in order to improve the intensity of joint material and base material tubing coupling part, carry
High joint compressive resistance, the application provide one kind with PB Polybutene-1 (PB-1) and trans-polyisoprene (TPI) as raw material
The preparation method of composite, and it is applied to floor heating pipe joint material.Why this composite can be applied to ground
The joint material main cause of heating coil be the composite except can in addition to sweat soldering, also with pyrocondensation performance, so as to
Improve the intensity of junction.There is composite the cardinal principle of hot shortness to be：There is the property of shape memory using composite
Can, i.e., in the composite, due to the presence of cross-linked structure, the permanent shape of material can be fixed, turns into stationary phase；And composite wood
The crystal region in uncrosslinked TPI components, PB-1 components in material as shape memory can anti-phase, so as to the interim shape of fixation
Shape and it is returned to permanent shape.Thus, in material preparation process, what sulfidization molding process obtained is the permanent shape of material,
And the material of shaping is subjected to enlarging again, obtain the temporary shapes of material；In material hot melt welding process, material on the one hand meeting
Fusion weld, still further aspect not only have there is also the transition from temporary shapes to permanent shape so as to obtain composite
Sweat soldering performance, and there is pyrocondensation performance.Thus, the composite can increase joint material when as floor heating pipe joint
The bonding strength of material and matrix tubing, compressive resistance of the material in joint is improved, extends the materials'use life-span.
The formula feature of the composite be not only by PB Polybutene-1 (PB-1) and trans-polyisoprene (TPI) both
Material of main part forms, and also introduces a small amount of white carbon and the silane coupling agent vinyl trimethoxy silane containing double bond.In vain
The introducing of carbon black can reduce the cost of material to a certain extent；The effect of silane coupler containing double bond is：On the one hand, can change
Kind compatibility between white carbon and matrix, still further aspect, double bond structure may participate in the cross-linking reaction of material, multiple so as to make
Condensation material forms big cross-linked network, i.e., comprising TPI phases chain structure, PB-1 phases chain structure, the chain structure of even silane, Jin Erwei
Material provides more powerful convergent force.Thus, it is the advantages of the rubber and plastic connector product of composite preparation：Using tradition heat
While fusion welding, material also has pyrocondensation performance, the bonding strength of increase joint material and matrix tubing, improves material and is connecing
Compressive resistance at head.
The purpose of the present invention is realized using following technical measures：
A kind of composite rubber-plastic material as floor heating pipe joint material, it is characterised in that：Include the group of following mass fraction
Point：
PB Polybutene-1 (PB-1)：70-40
