Speed of agitator 400-600r/min, it is naturally cold go after produce the present invention environmentally friendly nail-free glue for building.
9. a kind of preparation method of environmentally friendly nail-free glue for building according to claim 8, it is characterised in that the step
For：
Step one, weigh on request and prepare each component raw material；
Step 2, coupling agent, filler, nano silicon, nano zine oxide, nano titanium oxide are mixed and add high-speed stirred
In machine, rotating speed is 350r/min, stirs 30 minutes, obtains mixture A；
Step 3, adds the deionized water of 13 times of polyvinyl alcohol and its weight, is then heated up to 94 DEG C and boils in a kettle.
40 minutes, polyvinyl alcohol is completely dissolved, is cooled to 55 DEG C, add polyvinyl acetate, methyl acetate, defoamer, plant
Rubber powder, inorganic tackifier, insulated and stirred 50 minutes, speed of agitator 350r/min, then it is cooled to 35 DEG C, sequentially add step 2 system
Standby mixture A, neopelex, preservative, continue insulated and stirred 1.5 hours, and speed of agitator 500r/min is natural
It is cold go after produce the present invention environmentally friendly nail-free glue for building.
