Description
Technical field
The present invention relates to the preparation technology of water-band, particularly relate to the production technology of the fire hose for the preparation of TPU inner liner, F16L11 classification can be belonged to according to IPC IC table.
Background technology
Fire hose is used to the flexible pipe transporting the anti-flaming liquid such as water under high pressure or foam.Traditional fire hose is generally the braid that plastic flat fiber, synthetic fibers or yarn, flax braid etc. are formed by weaving according to longitude and latitude is that main body realizes the withstand voltage framework main of water-band, but braid has space cannot stop moisture to spill, then at braid internal layer lining material to realize water resistance.In addition, in order to protect braid not frayed, some fire hoses also at the additional one deck of organization level skin as the external coating of wear resistant resin material, this external coating has also been held concurrently withstand voltage with effect that is against leakage.Lining material mainly chooses the material meeting high pressure resistant, oil resistant, the feature such as corrosion-resistant, lightweight, soft.Lining material can be rubber, latex, plastic-coated, polyurethane etc.Choosing of external coating is based on weatherability and wearability, can use neoprene, acrylic rubber, chlorosulfonation rubber, lactoprene etc., also uses polyvinyl chloride resin.
Based on the performance requirement of lining material, there is a kind of TPU (Thermoplastic Polyurethanes, Chinese full name is TPUE) material then particularly suitable.TPU is by the linear polymeric material of vulcabond and macromolecular polyol, the common reactive polymeric of chain extender (being generally glycol or diamines).It has had both the many valuable characteristic from rubber to plastics: one is that intensity is high, and its tearing strength is about 3 times of natural rubber; Two is that wearability is good, is about the 3-5 of natural rubber doubly; Three is that oil resistivity is good, and the compatibility of non-mineral oil is little, weathers hardly in fuel oil; Four is that weatherability is good, under 80 DEG C to 90 DEG C hot environments, use not modification continuously, not brittle under-50 DEG C to-70 DEG C low temperature.Therefore, adopt the fire hose of TPU inner liner, except there is all advantages of rubber water-band, also there is excellent high pressure resistant, oil resistant, weather-proof, corrosion-resistant, the resistance to feature such as to circumnutate, and lightweight, the soft convenience of use, unit weight is lighter than rubber lining water-band by more than 40%.
TPU macromolecular chain is alternately made up of the ammonia ester of polarity or polyureas segment (hard section) and aliphatic polyester or polyether segment (soft section).The high polarity of this soft, firmly intersegmental incompatibility and polyurethane molecular makes intermolecular interaction form crystal region, and produces microphase-separated.This crystal region plays similar filler grain, not only makes it have high elasticity at normal temperatures.And strengthening action is risen to its physical and mechanical properties.Therefore TPU is the same with other macromolecular material, and performance and its molecular weight, intermolecular force (hydrogen bond and Van der Waals force), the toughness of segment, crystallization tendency, the factor such as Branching and cross-linking and substituent position, polarity and volume size have close relationship.
Existing TPU fire hose directly plastic flat fiber, synthetic fibers or yarn, flax braid solid is compiled into water-band pipe, then by manufacturing the TPU material of certain proportioning or other materials forms the outer cladding pipe of TPU internal lining pipe or other materials through extruding cooling, then the outer cladding pipe coated with adhesive of the TPU internal lining pipe manufactured and other materials is inserted in bond fixedly forms.But still come with some shortcomings: the material mixture ratio of 1.TPU internal lining pipe is reasonable not.2. manufacturing process is comparatively traditional, not efficiently.
Summary of the invention
Therefore, the present invention proposes a kind of material of the TPU of improvement internal lining pipe and draw the preparation method of being inserted in a kind of new TPU fire hose that cylinder weaving layer cylinder operates again after being processed to form cylinder inner liner in advance, there is the characteristic of better inner liner, and in manufacturing process, there is advantage.
