Flexible chain is alternately connected into macromolecular by the present invention using the method for block copolymerization with rigid chain, is in the small soft silk of normal temperature
Rubbery state, hard section is gathered together in glassy state or crystalline state, forms physics crosslinking points, and material has the numerous characteristics of rubber,
Elastomer product is at -50 DEG C -- there is good toughness, tear-proof and Flex-Fatigue within the temperature range of 140 DEG C.
Most of it is a kind of thermoplastic heat molten type superfines present invention adds TPU powder, i.e. polyurethane powder, with
Material has good cohesive force, and temperature range while have initial stage peel strength and heat resistance high and wider is with suitable
Different processing are answered to want, high rigidity, high resiliency, low temperature laminating, bonding is rapid, and production efficiency is high, bonding scope extensively, can be bonded many
Kind of material, can be heated repeatedly, repeatedly bonding, and TPU powder is added in polyvinyl chloride resin, and both are well mixed, good penetrability, can be with
Improve the elasticity and heat-resisting quantity of material.
The present invention is by CaCO3（Calcium carbonate）Inserts carries out following special activation process, directly adds with general inserts
Enter different, activation process is carried out before composition of raw materials, the technique and flow for the treatment of have particularity, first 1500 purposes
CaCO3 is added in mixer high, then bridging agent（Can make by oneself）25% pure solution is configured to, with mixer at a high speed
Rotate, be homogeneously added into CaCO3 inserts, after stirring 20 minutes, use low rate mixing instead 30 minutes, after dynamic is dried, i.e.,
Can be used；CaCO3 dispersivenesses after treatment increase, and increase with polyvinyl chloride resin binding ability, and being added to can reduces cost in being formulated
Enhancing and dispersion effect can be played again.
Also using the SBS superfines of specially treated, SBS is the block copolymer of styrene and butadiene to the present invention.Tool
There is two phase structure：Polybutadiene phase-continuous phase, polystyrene phase-dispersed phase.It is similar to butadiene-styrene rubber, SBS can with water,
Weak acid, alkali etc. are contacted, with excellent tensile strength, big surface friction coefficient, low temperature performance well, excellent electrical properties, processability
The thermoplastic elastomer (TPE) of characteristic can well be waited.Ultra-fine SBS powder is processed by special processing and special modified technique, with non-
Often good mobility, is greatly improved its performance.Do not lump at normal temperatures, thoroughly widened the range of application of SBS.And benzene
Ethene-butadiene-styrene (SBS) triblock polymer is one of maximum thermoplastic elastomer (TPE) of current yield in the world,
The elasticity with rubber, is melt into the material of plasticity under normal temperature under high temperature.Because it has excellent tensile property, good resistance to
The skid resistance of low temperature properties, gas permeability, dissolubility and uniqueness and be widely used in the fields such as shoemaking, modifying plastics, asphalt modification.
Because SBS polarity is small and oil resistivity is poor, use it and be restricted.Polar group can be introduced on SBS chains by functionalization
Group, drastically increases the heat-resisting of SBS, resistance to oxidation, adhesive property and water absorbing properties.1 part is added in 30 parts of SBS powder systems
CPE improves compatibilities of the SBS to polar polymer first, improves SBS polarity.It is solvent with 60 parts of hexamethylenes, adds in a solvent
Enter adhesive and make diluent, using 6 parts of undersaturated vulcanizable liquid polymer materials（Liquid NBR）With 0.5 part of vulcanizing agent
And 0.35 part of catalyst is blended, the SBS rubber cements to being blended are heated to 60 degree and are stirred continuously uniformly, using high temperature spray-drying legal system
Specially treated SBS powder, the rubber powder of system can be such that it is crosslinked well with other materials, and can be the oil resistant of elastomer
Property, cold resistance and the ozone aging resistance of the diaphragm, elasticity and wearability greatly strengthen.
