A kind of aqueous, environmental protective essence is mounted glue
Technical field
The main a kind of essence of the present invention is mounted glue, relates in particular to a kind of aqueous, environmental protective essence and mounts glue.
Background technology
When making hard-cover gift box by hand, to the initial bonding strength of glue with hold viscosity higher requirement is arranged, in order to make glue that the viscosity of holding of good initial bonding strength and length be arranged, past is when glue, toluene, dimethylbenzene rosin have been used, the raw materials such as SBS adopt the method for water and milk to be made, because this technique has been used toluene and dimethylbenzene, (smell is large) not environmental protection so obnoxious flavour exceeds standard.
Summary of the invention
The object of the invention just provides a kind of aqueous, environmental protective essence and mounts glue.
The present invention is achieved by the following technical solutions:
A kind of aqueous, environmental protective essence is mounted glue, and it is comprised of the raw material of following weight parts:
Pre-emulsification agent 360-400, seed monomer 40-45, dropping monomer 180-185, initiator 1 16-18, initiator 2 90-95, functional aid 18-22;
Wherein, described pre-emulsification agent is comprised of the raw material mixing of following weight parts: deionized water 300-350, sodium hydroxide 8-10; Vinylformic acid 30-35, OP-10 4-5;
Described seed monomer is mixed by the following weight parts raw material and forms: vinylformic acid 1-2, Butyl acrylate 22-26, vinyl acetate between to for plastic 10-12, diacetone 0.3-0.8, polyacrylamide 0.3-0.8;
Described dropping monomer is comprised of the raw material mixing of following weight parts: vinylformic acid 5-8, Butyl acrylate 115-125, vinyl acetate between to for plastic 53-58, diacetone 1.2-1.8, polyacrylamide 1.2-1.8;
Described initiator 1 is the ammonium persulfate aqueous solution of 2.8-3% for concentration;
Described initiator 2 is the ammonium persulfate aqueous solution of 2-2.2% for concentration;
Described functional aid is comprised of the raw material mixing of following weight parts: concentration is ammonia soln 8-12, ethylene glycol 6-10, the silicone antifoam agent 1-2 of 25-28%.
Described aqueous, environmental protective essence is mounted the preparation method of glue, may further comprise the steps:
The pre-emulsification agent of above-mentioned weight part is joined in the reactor, and the temperature that raises gradually adds seed monomer and the initiator 1 of above-mentioned weight part during to 75-80 ℃; React after 30-35 minute, the control temperature drips dropping monomer and the initiator 2 of above-mentioned weight part at 82-86 ℃, and time for adding is between 4-5 hour; After being added dropwise to complete, be warming up to 88-90 ℃, be incubated 1-1.5 hour, normal temperature is cooled to 45-50 ℃, adds the functional aid of above-mentioned weight part, mixes, and namely gets described aqueous, environmental protective essence and mounts glue.
Advantage of the present invention is:
The essence that the present invention produces is mounted glue environmental protection, good for health, without bad smell, do not contain toluene and the objectionable impuritiess such as dimethylbenzene and heavy metal, have high solids content, high tenacity, make institute's product of mounting wrinkle resistant, not yielding, rate of drying is very fast under the normal temperature, and efficient efficient is high, go keep a public place clean performance and coating performance of stain good, the initial bonding strength of its glue and hold viscosity and all can reach the processing requirement of making hard-cover gift box.
