Abstract
The present invention relates to high molecular polymer putty glue and a production process thereof. The copolymer of butyl acrylate and vinyl acetate, and hydroxyethyl cellulose which is added as protective colloid are mainly prepared into the high molecular polymer putty glue. The high molecular polymer putty glue substitutes for the existing 107 putty glue. The high molecular polymer putty glue has the characteristics of good toughness, good elasticity, high hardness, high bonding strength, easy drying, good batch scraping performance, no harmful substances of formaldehyde, etc. The high molecular polymer putty glue is new generation ideal environmental protection type high molecular polymer putty glue.
Description
Technical field:
The present invention relates to a kind of production method of caulk compound, refer more particularly to a kind of macromolecular polymer putty glue and this colloidal production method thereof.
Background technology:
Employed colloid mainly is 107 glue when preparation putty in the market, and this colloid is through the formal gained by water-soluble poval.The putty made with these colloids in use has following defective: the poor toughness of putty, and easily embrittlement easily forms the crack; Elasticity is low, and hardness is low, is difficult for polishing, is not easy to construction; Poor water resistance is subject to humidity; Weathering resistance is poor, the easy temperature influence of performance, and stability is poor; Viscosity is low, and the finish paint poor adhesive force is easily flaked; Time of drying is long, influences construction speed; Contain human body and the deleterious formaldehyde of environment.
Summary of the invention:
The object of the present invention is to provide a kind of good toughness, good springiness, hardness height, cohesive strength height, time of drying short and do not contain the caulk compound of harmful material such as formaldehyde.This caulk compound excellent property is environmentfriendly products of new generation, has vast market prospect.The present invention realizes in the following way: adding Natvosol by the multipolymer of butyl acrylate and vinyl acetate is that protective colloid forms, and in finished product, solids content is about 8%.
Embodiment:
Below in conjunction with embodiment in detail, implementation procedure of the present invention is described in detail.
The weight percent of each composition of raw materials is respectively in the macromolecular polymer putty glue involved in the present invention:
Water 91.7%
Natvosol 1.5%
Butyl acrylate 2.3%
Vinyl acetate between to for plastic 4.0%
Ammonium persulphate 0.1%
Emulsifying agent 0.2%
Auxiliary agent 0.2%
The production method step is as follows:
1, gets the raw materials ready by above-mentioned prescription, earlier partial emulsifier and butyl acrylate are added in the entry, stir;
2, in reactor, Natvosol and remaining emulsifying agent are added in the entry, temperature is controlled at 90 ℃, stirs;
3, when temperature drops to 80 ℃, add the prepared raw material of step 1, drip vinyl acetate between to for plastic and ammonium persulphate simultaneously, fully react for making it, make the particle size of polymkeric substance be controlled at 0.2-0.8um, the dropping time was controlled at 2 hours;
4, when temperature is reduced to 60 ℃, add auxiliary agent, to increase colloid toughness;
5, when temperature is reduced to 40 ℃, promptly make the finished product high molecular polymer colloid.
Claims (2)
1, a kind of macromolecular polymer putty glue, it is characterized in that: the weight percent of each composition is respectively in the colloid prescription: water 91.7%, Natvosol 1.5%, butyl acrylate 2.3%, vinyl acetate between to for plastic 4.0%, ammonium persulphate 0.1%, emulsifying agent 0.2%, auxiliary agent 0.2%.
2, a kind of production method of macromolecular polymer putty glue as claimed in claim 1, it is characterized in that production craft step is: A gets the raw materials ready by prescription, and partial emulsifier and butyl acrylate are added in the entry, stirs; B adds Natvosol and remaining emulsifying agent in 90 ℃ the water in reactor, stirs; When C drops to 80 ℃ when temperature, add the prepared raw material of steps A, drip vinyl acetate between to for plastic and ammonium persulphate simultaneously, the dropping time is 2 hours; When D reduces to 60 ℃ when temperature, add auxiliary agent; When the E temperature is reduced to 40 ℃, get finished product.
