A kind of aqueous, environmental protective essence mounts glue
Technical field
The main a kind of essence of the present invention mounts glue, particularly relates 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 and have higher requirement, the initial bonding strength had to make glue holds viscosity with long, past is when glue, employ toluene, dimethylbenzene rosin, the raw material such as SBS adopts the method for water and milk to be made, and because this technique employs toluene and dimethylbenzene, so obnoxious flavour exceeds standard, (smell is large) not environmentally.
Summary of the invention
The object of the invention is just to provide 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 mounts glue, and it is made up 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 mixed by the raw material of following weight parts and forms: deionized water 300-350, sodium hydroxide 8-10; Vinylformic acid 30-35, OP-10 4-5;
Described seed monomer is mixed by 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 mixed by the raw material of following weight parts and forms: 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 for concentration be the ammonium persulfate aqueous solution of 2.8-3%;
Described initiator 2 for concentration be the ammonium persulfate aqueous solution of 2-2.2%;
Described functional aid is mixed by the raw material of following weight parts and forms: concentration is ammonia soln 8-12, ethylene glycol 6-10, the silicone antifoam agent 1-2 of 25-28%.
Described aqueous, environmental protective essence mounts the preparation method of glue, comprises the following steps:
The pre-emulsification agent of above-mentioned weight part is joined in reactor, when raised temperature is to 75-80 DEG C gradually, adds seed monomer and the initiator 1 of above-mentioned weight part; React after 30-35 minute, control temperature is at 82-86 DEG C, and drip dropping monomer and the initiator 2 of above-mentioned weight part, time for adding is between 4-5 hour; After being added dropwise to complete, be warming up to 88-90 DEG C, insulation 1-1.5 hour, normal temperature is cooled to 45-50 DEG C, adds the functional aid of above-mentioned weight part, and mixing, obtains described aqueous, environmental protective essence and mount glue.
Advantage of the present invention is:
The essence that the present invention produces mounts glue environmental protection, good for health, without unpleasant odor, not containing toluene and the objectionable impurities such as dimethylbenzene and heavy metal, there is high solids content, high tenacity, make mounted product wrinkle resistant, not yielding, under normal temperature, rate of drying is very fast, and efficient efficiency is high, go stain keep a public place clean performance and coating performance good, the initial bonding strength of its glue and hold viscosity and all can reach the processing requirement making hard-cover gift box.
