A kind of waterproof hot melt
Technical field
The utility model relates to a kind of bonding agent, relates in particular to a kind of waterproof hot melt.
Background technology
PUR is mainly used in the firm effect between bonding object and object, during use, PUR is heated, PUR melted by heat, thereby will between object, be bonded, and existing PUR does not possess the function of waterproof, in using some special industries, to the water proofing property of PUR, require high, to use, make troubles, PUR is sold for single products afterwards in production simultaneously, and user needs to melt by heater or naked light after buying, and causes and uses trouble.
In view of this, the inventor, for the above-mentioned defect further investigation of PUR in prior art, has this case to produce then.
Utility model content
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of waterproof hot melt, it have have water resistance strong, use more convenient.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme:
A kind of waterproof hot melt; comprise and be provided with successively from outside to inside waterproofing guaranteeding jacket, collet, PUR shell and PUR; described PUR shell is provided with hole for injecting glue, plastic hole and the heating tube communicating with waterproofing guaranteeding jacket, collet, and one end of described waterproofing guaranteeding jacket is provided with handle.
The utility model advantage is compared with prior art: owing to being provided with above structure, the utility model increases waterproof jacket and has water-proof function, by heating tube, PUR is heated, and uses more conveniently, can reclaim again housing injecting glue again, saves production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
