Domain has a wide range of applications.PUR glue in the prior art pair is substantially hot melt adhesive, carry out using when carry out heating and melt
It can be sprayed after change, it is inconvenient to use, and PUR glue tack in the prior art is poor, needs to heat ability after cooling
There can be preferable viscosity.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind can directly be sprayed, the PUR glue that tack is good and
Its production method.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows: it is a kind of can direct spraying PUR glue, by such as
It is lower at being grouped as:
5-7 parts of tackifier, 40-60 parts of liquid polyurethane latex solution, 15-20 parts of solvent and 1-3 parts of modifying agent.
Preferably, the tackifier are phenolic resin tackifier.
Preferably, the solvent is ethyl acetate.
Preferably, the modifying agent is nanofiller.
Preferably, the nanofiller is one of nano-titanium dioxide, nano silica and nano-stannic oxide
Or it is several.
Preferably, the partial size of the nanofiller is 40-220 nanometers.
It is a further object to provide it is a kind of as previously described can direct spraying PUR glue production method,
Include the following steps:
Step 1: 15-20 parts of solvents and 40-60 parts of liquid polyurethane latex solutions are placed in mixing drum and are sufficiently stirred；
Step 2: 1-3 parts of modifying agent are added in mixing drum and are stirred；
Step 3: it using 5-7 parts of tackifier of preceding addition and is sufficiently mixed in product mix.
Preferably, the mixing speed in the step 1 is 500-1000rpm, and the whipping temp in the step 1 is

Preferably, the mixing speed in the step 2 and step 3 is 500-1000rpm, the step 2 and step 3
In whipping temp be 25 DEG C -35 DEG C.
By adopting the above technical scheme, due to compounding PUR glue and solvent and modifying agent, so that on the one hand
The viscosity of glue on the other hand can be ensured by nano modifier, and increase just after mixing with solvent with direct spraying
Stick so that can not only be sprayed, but also may insure preferable viscosity.
Detailed description of the invention
Fig. 1 be the present invention in can direct spraying PUR glue production method flow chart.
