But after long-term preservation, inflatable dinghy may occur bacteria breed, it is mouldy situations such as.Therefore it is necessary to study one kind It can achieve the inflatable dinghy of long-term antibacterial effect, to guarantee the health of user.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of preparation methods of inflatable dinghy with long-term antibacterial function.
A kind of preparation method of the inflatable dinghy with long-term antibacterial function carries out as steps described below:
Step 1: the preparation of internal layer PVC film
A, material is weighed according to formula, is gradually added weighed object in the case where low-speed running in a high speed mixer Material, it is at a high speed 1000-1400rpm, temperature rises to 150-160 that then high speed is lower, which operates 300-350s, low speed 60-100rpm, DEG C, it is discharged to cold mixing 3-5min in cold mixing machine automatically, natural temperature is cooling, then passes to intermediate bucket and is uniformly mixed；
B, the material mixed is passed in planetary extruder, setting is extruded as 130-140 DEG C, then flows into and rolls in turbine It is sent after gelatinization to filter and is filtered；
C, filtered colloidal objects are rolled using six roll calendar of inverted L shape；
Step 2: the preparation of outer layer PVC film
A, material is weighed according to formula, is gradually added weighed object in the case where low-speed running in a high speed mixer Material, it is at a high speed 1000-1400rpm, temperature rises to 100-130 that then high speed is lower, which operates 300-350s, low speed 60-100rpm, DEG C, it is discharged to cold mixing 12-15min in cold mixing machine automatically, natural temperature is cooling, then passes to intermediate bucket and is uniformly mixed；
B, the material mixed is passed in planetary extruder, setting is extruded as 130-140 DEG C, then flows into and rolls in turbine It is sent after gelatinization to filter and is filtered；
C, filtered colloidal objects are rolled using six roll calendar of inverted L shape；
Step 3: the preparation of inflatable dinghy
A, composite material, structure are prepared using lamination coating mode are as follows: outermost layer is outer layer PVC film, and inside is successively pasted Warp knit inlaid thread cloth and internal layer PVC film are closed, fitting layer 2-3 warp knit inlaid thread cloth and internal layer PVC film is repeated, obtains composite material；
B, composite material is subjected to cooling and oil removing through water-carrying groove；
C, composite material is made by inflatable dinghy using conventional method.
Preferably, the internal layer PVC film, the main component including following weight percent:
