Description

Size putty

The present invention relates to a kind of size putty, the two component putty of particularly a kind of normal temperature quick-drying.IPC E04B1/66。

As everyone knows, putty has many kinds, the putty that varnishes furniture and be used to feel secure as at present, the architectural putty that is used for the build-in windowpane, scrape the putty of embedding bottoming usefulness when lacquer lathe or automobile case, also have oil loam, water putty etc., though this class putty making method is simple, but the shortcoming that exists is more, and for example dried solid time is longer, easy to crack, poor with the bonding force of the scope of operation, easily peel off or the like.Chinese patent CN86101069A patent application discloses a kind of baking putty cross-linked latex type, though overcome the shortcoming of some above-mentioned putty, but its production technique is extremely complicated, when producing in batches, at equipment with technically all have higher requirements, cost is also higher, and needs baking when solidifying because of it, so its use range is narrow.And the multiple putty of production and sales at present, make the production of lacquer factory " the H07-5 epoxy is from dried putty " or the like as " the ARC normal temperature fast setting putty " of the Japanese Northwest 99 putty, HeFei University of Technology's development, " polyester putty " and the Shanghai fashion that Shanghai Paint Factory produces, although it is better that this class putty all has manufacturability, be coated with and mend quality than characteristics such as height, but its reparation technology complexity, cooling, it is more to consume energy, thereby product cost is higher.

It is simple and easy to the purpose of this invention is to provide a kind of production technique, power consumption is few, used production unit requires low, and the production process three-waste free discharge is actual easy to use, the coating curing time is short, easily polishing is not ftractureed, and bonding force is strong, can be widely used in metal or nonmetallic surface and be coated with the quick-acting putty of ambient cure, particularly a kind of pair of component putty of mending or fitting up.

The present invention adopts the first component putty base-material and the second component solidifying agent to produce respectively and packing respectively, mixes according to a certain ratio more in use that to make be operational technique means thoroughly, realizes the object of the invention.

The first made component putty base-material contains polyester binder, promotor and filler, produces through mixing thoroughly by proportioning.

The second made component solidifying agent contains initiator, white carbon black, produces through mixing thoroughly by proportioning.

Of the present invention being further characterized in that: used promotor is cobalt naphthenate solution, used initiator is a cyclohexanone peroxide, and used filler is the mixture that contains talcum powder, titanium dioxide, diatomite, ground barium sulfate, white carbon black powder, dry powder, iron black powder and glass microballon.

The first component putty base-material consists of (parts by weight):

Polyester binder:

337 resin 23-27 parts

196 resin 23-27 parts

182 resin 23-27 parts

3301 resin 23-27 parts

Promotor:

Cobalt naphthenate solution 0.4-0.8 part

Filler:

Talcum powder 27-29 part

Fine particle calcium carbonate 13-15 part

Titanium dioxide 9-11 part

Ground barium sulfate 7-11 part

Diatomite 6-9 part

White carbon black powder 0.5-2 part

Iron black powder 0.5-2 part

Glass microballon 13-17 part

(synthetic materials factory in Tianjin provides)

Dry powder (water-ground limestone) 3-5 part

The second component solidifying agent is formed (parts by weight):

Cyclohexanone peroxide 40-60 part

White carbon black powder 40-60 part

When reality was used, the proportioning of first and second pair component was: the first component putty base-material 100(parts by weight) add and join the second component solidifying agent 0.5-10(parts by weight), make can be for using through mixing thoroughly.

The preparation method of putty of the present invention is as follows:

1. the preparation of first component:

A. the preparation of polyester binder: 337 resins, 196 resins, 182 resins, 3301 resins are stirred in the stainless steel steel basin by said ratio, add promotor, mixing then.

B. filler: various fillers are mixed by said ratio.

C. filler is added in the polyester binder, stirs, and grind more than twice with three-roll grinder, irritate barrier packaging, the preparation of first component finishes;

2. second component preparation: by aforementioned proportioning cyclohexanone peroxide and white carbon black are stirred together, grind evenly, the filling bag.

It is simple that the present invention has production technique, save energy, and used production unit requires low, the production process three-waste free discharge, product cost is low, and is easy to use, and weak point can be widely used in the metal and nonmetal surface and was coated with and mends and finishing set time.

Below the invention will be further described with embodiment.

Embodiment

Get respectively 25 kilograms of 337 resins, 196 resins, 182 resins, 3301 resins, puddle evenly, add 0.5 kilogram of cobalt naphthenate then, continue to puddle evenly.

In the polyester binding agent composition that obtains, add 29 kilograms of talcum powder, 15 kilograms of fine particle calcium carbonates in the above, 11 kilograms of titanium white parts, 5 kilograms of dry powders, 9 kilograms in diatomite, 16 kilograms of glass microballons, 11 kilograms of ground barium sulfates, 2 kilograms in iron black powder, 2 kilograms in white carbon black powder, then said mixture is stirred, and, irritate barrier packaging with three-roll grinder grinding three times, first component preparation so far finishes.

Get 50 kilograms of cyclohexanone peroxides, 50 kilograms of white carbon blacks with the two mixing, and grind evenly, irritate the bag packing, promptly become second kind of component.

When reality is used, get the first component putty base-material, 100 powder, three parts in the second component solidifying agent can use after mixing.

Size putty of the present invention checks its use properties as follows through synthesis material quality supervision, inspection and testing station, Hebei province:

The putty outward appearance: pale yellow, exquisiteness does not have the caking paste.

Appearance of coat: do not split not bulge after doing.

Solid content: 82%.

Time of drying: 25 minutes.

Grinability: easily polishing, be not stained with sand paper.

Shock-resistance: 800(newton. centimetre)

Sticking power: 250(newton. square centimeter)

It will be understood by those skilled in the art that any improvement that does not exceed the scope of the invention, all within the scope of the present invention.
