Description
Technical field
The present invention relates to a kind of latex composition, relate in particular a kind of environmental protection water-resisting type latex composition that can be used for artificial grassplot back glue.
Background technology
At the end of the eighties in last century, chinampa starts to enter Chinese market, from 1997, enters China till now comprehensively, along with school starts extensive reorganization and expansion, and the sports field upgrading in campus, chinampa consumption starts to increase rapidly.Along with the continuing of national economy, continuous renewal stable, fast-developing, people's life idea is progressive and the rapid raising of the whole standard of living of people, the Sport & Casual consumer group will further expand.As outdoor activity place, first-selection is artificial lawn, and tomorrow requirement has a high potential, and chinampa has greatly the trend that replaces natural lawn, has wide development space.In producing the process of chinampa, having a topmost quality index is exactly to detect the maximal force that straw fiber comes off from end back.
In producing the process of chinampa, the back of the body is composite fibre materials at the normally used end, as polypropylene.Chinampa is that straw fiber is passed through to the woven back on earth of tufting, and wherein single straw fiber, through the end back of the body, is attached to end back.The position of each straw fiber must be fixed, otherwise in use, straw fiber can come off.The object of end back of the body gluing is the dimensional stability of in use protecting straw fiber and improving the finished product.This characteristic is commonly called withdrawal force.
It is at present general that straw fiber and the end back of the body are bonded together to method is at end back painting one deck latex.Such two faces (straw fiber and the end back of the body) are connected together by gluing, and then whole lawn can be sent to many groups hot-work storehouse conventionally.The Main Function in hot-work storehouse is the moisture in heating volatilization latex composition.Make latex film forming solidify, straw fiber and the end back of the body are just bonded together so simultaneously.From hot-work storehouse out after, rolling packing warehouse-in is carried out in Slow cooling sizing.In the whole course of processing, the adhesiveproperties of straw fiber and the end back of the body is most critical.
Nowadays the carboxylic styrene butadiene latex using on market is a kind of unsaturated latex, by divinyl and vinylbenzene and carboxylic monomer terpolymer, formed, because domestic latex enterprise technology equipment is limit, cause the residual more pungent smell that has of benzene monomer, do not meet this world today's theme of environmental protection Sustainable development completely.
Chinampa belongs to outdoor pavement, can often be subject to illumination fog precipitation weather invasion and attack, general carboxylic styrene butadiene latex in the market, and water-fast rear detection straw fiber withdrawal force obviously declines more than 5～10%.
Summary of the invention
Based on above-mentioned technical problem, the invention provides a kind of environmental protection water-resisting type latex composition for artificial grassplot back glue.
The technology used in the present invention solution is:
An environmental protection water-resisting type latex composition for artificial grassplot back glue, includes polyvinyl acetate emulsion in this latex composition, and solid content is 50%-60%.
Above-mentioned polyvinyl acetate emulsion is to be made by vinyl acetate, functional monomer, emulsifying agent and protective colloid raw material.
Above-mentioned functions monomer is preferably one or more arbitrary combination in ethene, Hydroxyethyl acrylate, methyl methacrylate, vinylchlorid; Mentioned emulsifier is nonionic emulsifying agent, is specifically preferably one or more arbitrary combination in polyoxyethylene nonylphenol ether, polyoxyethylene octylphenol ether, sorbitan monostearate; It is 70%～95% that above-mentioned protective colloid is preferably one or more alcoholysis degrees, the polyvinyl alcohol that the polymerization degree is 200～5000.
It is Celvolit 1510 that above-mentioned polyvinyl acetate emulsion preferably adopts the trade mark of U.S.'s Celanese manufacturer production, Celvolit1518 and Celvolit 8481.
In above-mentioned latex composition, also can contain filler and pigment; Described filler is preferably one or more combinations in calcium carbonate, kaolin, diatomite, talcum powder, and particle diameter is 120-800 order; Described pigment optimization is black slurry, green slurry or carbon black.
In above-mentioned latex composition, also contain thickening material and water, thickening material and water add as required, so that the viscosity of latex composition system is adjusted to 10000～20000mPas; Described thickening material is preferably one or more combinations in polyvinylpyrrolidone, Xylo-Mucine, methacrylic ester, polyacrylamide, starch.
Preferably, above-mentioned latex composition is comprised of the material composition of following weight part:
The interpolation deal of water is that the viscosity of this latex composition system is transferred to 10000～20000mPas.
Preferably, above-mentioned latex composition is comprised of the material composition of following weight part:
The interpolation deal of water is that the viscosity of this latex composition system is transferred to 10000～20000mPas.
Preferably, above-mentioned latex composition is comprised of the material composition of following weight part:
The interpolation deal of water is that the viscosity of this latex composition system is transferred to 10000～20000mPas.
Useful technique effect of the present invention is:
(1) latex composition of the present invention is first for the production of chinampa, and the end back of the body that this latex is coated in to lawn simultaneously produces the bottom of spreadability.Also this latex can be directly used in to straw fiber in addition, or be dried after bonding together for straw fiber with the end back of the body of latex coating, like this straw fiber and carry on the back and just can bond together with the end of latex.For the dry back of the body that normally allows at the bottom of lawn by many groups hot-work storehouses.In this dry process, latex of the present invention has extraordinary moisture content boiling characteristics, and moisture content rapidly volatilization makes Energy Intensity Reduction, and production capacity promotes greatly.
(2) latex composition of the present invention can significantly improve withdrawal force, reduces glue consumption simultaneously, significantly reduces costs, environmental protection odorlessness, polyreaction residual monomer is nontoxic, can pass through the Green label Plus of the U.S., the GUT in Europe, and domestic GB18587 environmental certification.Can be used for motion grass, leisure grass and class lawn, supermarket.And obtained outdoor water-fast utilization, after the hot-water soak of chamber, detecting by experiment straw fiber withdrawal force does not only have to decline to having had on the contrary greatly to promote.
(3) latex composition of the present invention can mix the best proportioning of the use temperature that meets this area according to different terminals client location envrionment temperature, obtains the back of the body at the bottom of chinampa that soft durometer is moderate.In hot environment, improve the higher emulsion ratio of second-order transition temperature, guarantee suitable soft durometer after the gum of lawn; In low temperature environment, improve the lower emulsion ratio of second-order transition temperature, guarantee suitable soft durometer after the gum of lawn.
