The putty main body comprises the following components by part by weight: unsaturated polyester resin, organosilicon resin, saturated polyester resin, phenethylene, diacetyl dioxime, cobalt iso-octoate, sodium bentonite, titanium dioxide, barium sulphate and talcum powder; the initiating agent comprises the following components: cyclohexanone peroxide, dibutlyl phthalate and SiO2; and the preparation method comprises the following steps: preparation of the putty main body, the preparation of the initiating agent, and mixing for use.
Description
Technical field
The present invention relates to chemistry painting industry field, particularly a kind of preparation method of flame-retardant putty.
Background technology
Flame-retardant putty is often referred to the prime coat layer material of metallic surface pointing material, especially refers to the organic-silicon-modified unsaturated flame-retardant putty of a kind of Air drying air drying type.Pointing material for metallic surface generally has two classes: a class is aqueous putty, and another kind of is resin atomized ash.Chinese patent CN86101069 discloses formula and the production method thereof that a kind of name is called " cross-linked type latex emulsion baking putty ".This putty is to substitute organic solvent with water, do not fire nontoxic, free from environmental pollution, but the putty of this patent manufacturing must be dried in 50 minutes ability of about 110 ℃ bakings; Such drying conditions has greatly limited the use of its putty, due to main equipment and mobile inconvenient accessory etc., to at so high temperature, toast to be dried and be difficult to accomplish, while drying due to aqueous putty, moisture needs volatilization simultaneously, atomized ash film is loose, same inapplicable high-grade decoration, moreover the heat resisting temperature of conventional emulsions is below 180 ℃, inapplicable equally for this atomized ash of high temperature place.It is fair that another kind of resin atomized ash wherein be take the atomic lime putty over-all properties that unsaturated polyester resin is main raw material.Chinese patent 94115901 discloses formula and the production method of a kind of " polymer putty for quick drying at normal temperature ", this putty take that to mix unsaturated polyester be major ingredient, there is the solid fast of atomic lime putty, strong adhesion, snappiness, grinability, the features such as brushability is good, but the resin that this patent the is utilized conventional unsaturated polyester resin that is atomized ash, conventionally heat resisting temperature is below 150 ℃, simultaneously this putty do not have flame retardant properties this, thereby the thermotolerance of this putty and flame retardant properties can not meet railcar and other high-temperature field stokehold car, wheel shaft, the particular requirement of flue etc.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention be to provide a kind of good combination property, can life-time service in place below 250 ℃ and normal temperature can be from the preparation method of the dry organic-silicon-modified unsaturated flame-retardant putty of air drying type, with meet railcar and other high-temperature fields the particular requirement of stokehold car, wheel shaft, flue etc.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of preparation method of flame-retardant putty, this atomized ash is comprised of main body and two kinds of components of initiator: the weight ratio of main body and initiator is 100: 2, in use two kinds of components are mixed by this proportioning, described main body is comprised of the following composition in weight part: unsaturated polyester resin 50-56 part, silicone resin 10-15 part, saturated polyester resin 12-15 part, vinylbenzene 8-12 part, dimethylglyoxime 0.02-0.03 part, cobalt iso-octoate 1.4-1.8 part, sodium bentonite 3-5 part, titanium dioxide 9-11 part, barium sulfate 3-5 part, talcum powder 14-18 part; Initiator is comprised of the following composition in weight part: cyclohexanone peroxide: 58-62 part, dibutyl phthalate: 28-32 part, SiO
2: 12-14 part, described preparation method comprises the steps:
(1) main body: according to aforementioned proportion, unsaturated polyester resin, silicone resin and saturated polyester resin are dropped into and disperseed in cylinder, and add vinylbenzene, dimethylglyoxime, cobalt iso-octoate, stir 5-10 minute under the rotating speed of 800-1000r/min; Then add sodium bentonite, titanium dioxide to stir 10-15 minute under the rotating speed of 650-700r/min; Then add successively barium sulfate, talcum powder, then press and under the rotating speed of 450-550r/min, continue to stir 15-20 minute; Then after grinding, colloidal mill can be made into finished product main body;
(2) initiator: by weight by cyclohexanone peroxide, dibutyl phthalate and SiO
2, stir and grind even body of paste and can be made into finished product initiator;
(3) while using, press component proportioning: main putty: initiator=100: 2, mix and can use.
The beneficial effect of the inventive method is:
The present invention has determined above-mentioned component and content on the basis of great many of experiments, make to reach collaborative between each component, and when preparation host, substep adds, and selects and control to add the stirring velocity of each component, thereby reach following technique effect:
1) matrix resin of the present invention has adopted the mixture of unsaturated polyester resin, silicone resin and saturated polyester resin, and wherein unsaturated polyester resin has guaranteed the prerequisite of this atomized ash ambient cure; On this basis, then mix with saturated polyester resin, improved the resistance toheat of matrix resin, heat resisting temperature is brought up to more than 200 ℃ from 120 ℃.
2) further improved over-all properties: air setting solidity is good, had that heat-proof combustion-resistant, strong adhesion, good, the pliable and tough impact of corrosion resistance are good, construction is coated with and scrapes the premium propertiess such as grinability is good, anticorrosion noise reduction.After testing, indices reaches the requirement of GB and railway rower, also has the flame-proof heat-resistant performance that resistance to 250 ℃ of high temperature and fire-retardant rank reach III level simultaneously.
