Construction decoration crack filler
Technical field
The present invention relates to a kind of construction decoration crack filler.
Background technology
All the time, domestic construction decoration industry personage adopts multiple arrangement and method for construction, constantly make and use various materials, as: adopt bandage to mount with tackiness agent, copper strips nails on or bonds with flexible flat ash, the construction of also useful Resins, epoxy synthetic materials, all ways and means all can not solve the seam problem of various materials up hill and dale.Because of pointing should be considered the coefficient of expansion of various materials, consider to cover construction finishing material such as coating, the body of wall etc. on various art works surface again, should adapt to various environment and adapt to a series of problems of various weathers or the like again.
Usually adopt various ways on the market, loaded down with trivial details and dry slow, the contraction easily of construction technology more complicated, poor with various sheet material consistencies again, as adopt inflexible Resins, epoxy synthetic materials construction, it adopt the first and second two kinds synthetic, construction is complicated, seam such as dark or widely be difficult for disposable filling and leading up again, and drying is too slow, and tells Huang easily, and it is attractive in appearance to influence combination with decorative surfaces; Use the atom ash to fill out and connect, quality product own is too crisp, does not have cementability, and cracking does not reach the joint filling effect easily; Use the bouncing putty ash to fill out and connect, the too soft easy contraction of product own does not reach the joint filling effect.
About indoor and outdoor ceiling furred ceiling in the construction decoration industry, moulding is filled out seam and is used for woodwork, sheet materials such as calcium silicate board, glued board, fiberboard are filled out the linking material of seam, be the relatively major issue of headache of insider, filling out common faults such as seam contraction, cracking, brightness reversion is the already existing unsolved problem of adhesives of construction decoration always.
Summary of the invention
At the shortcoming that above-mentioned prior art exists, the long-pending experience of being engaged in this area work for many years of the inventor is through continuous design improvement, feasibility study repeatedly, a kind of construction decoration crack filler of invention the present invention.
The technical solution used in the present invention is: a kind of construction decoration crack filler, form by urea-formaldehyde resin, quartz sand, gypsum stone flour and auxiliary agent, its component proportion of composing is: urea-formaldehyde resin is 45 parts-55 parts, quartz sand is 25 parts-30 parts, the gypsum stone flour is 20 parts-25 parts, auxiliary agent is defoamer and water-holding agent, is 5 parts-8 parts.
It is synthetic that construction decoration crack filler of the present invention adopts multiple material such as the macromolecule copolymer resin, quartz sand, plaster stone of import to refine, and it belongs to water-based, health environment-friendly, and easy construction is converted water and is stirred evenly and get final product; Fill out easily and connect fullly, do not shrink,, fast drying good with various material consistencies, not brightness reversion, cohesive force extra-heavy, firm, uprisingly split, forever durable, be without fear of an attack from the rear extremely.
