Description
Technical field
The present invention relates to a kind of putty, especially relate to a kind of high attachment automobile putty and preparation method thereof.
Background technology
When body of a motor car surface there is seam, weld seam and touch cut to pieces after the defect such as the pit that causes and cut time, need by being coated with Puttying and filling up and polishing could forming smooth surface, for last surface spraying meticulously.
Putty conventional at present has acid alcohol putty, epoxy putty and atomized ash etc.The drying of acid alcohol putty is comparatively large by drying temperature, humidity effect, and hardness is low, poor adhesive force and being eliminated gradually; Epoxy putty, owing to using a large amount of organic solvent to reduce viscosity, causes its existence to sting priming paint phenomenon, often occurs cracking, collapses block phenomenon; And conventional atomized ash is too fast for set time, operable time is short, and workability is poor, and there is slight moisture absorption phenomenon.
Such as, application publication number CN103666003A, the Chinese patent of Shen Qing Publication day 2014.03.26 has disclosed battle wagon a kind of and has repaired special putty, it is made up of base-material and the two component of solidifying agent, base-material is made up of following component with parts by weight, Pneumoperitoneum pressure resin 100 parts, cobalt iso-octoate 0.5 ~ 1 part, xylidine 5 ~ 7 parts, t-butyl catechol 0.8 ~ 1.0 part, white carbon black 6 ~ 8 parts, titanium dioxide 8 ~ 10 parts,-325 order talcum powder 35 ~ 45 parts,-325 order diatomites in powder 10 ~ 20 parts,-325 order terra albas 10 ~ 20 parts, convex Attapulgite 8 ~ 10 parts, 0.5 ~ 1 part, ultramarine, wherein solidifying agent is made up of following component with parts by weight: cyclohexanone peroxide 35-45 part, benzoyl peroxide 35 ~ 45 parts, 2 ~ 3 parts, acetone, white carbon black 13 ~ 15 parts.This putty is atomized ash, and it has the following disadvantages: (1) is too fast for set time, and operable time is about 10min, and workability is poor; (2) the easy moisture absorption, is unfavorable for drying, requires higher to execution conditions; (3) in construction process, easily there is sagging phenomenon, cause upper-thin-lower-thick; (4) when solidifying, the easy shrinkage cracking of putty; (5) solidify rear surface comparatively coarse, and easily produce sand holes and bubble; (7) sticking power and resistance poor performance, easily get loose in judder or under clashing into, occur collapsing block.
Summary of the invention
The present invention is the problems referred to above existing for the automobile putty in order to solve prior art, provides a kind of scientific formulation reasonable, strong adhesion, rate of drying is fast, easy blade coating, and workability is excellent, the smooth flawless of smooth in appearance after solidification, the height attachment automobile putty of easily polishing.
Present invention also offers a kind of high attachment automobile preparation method of putty, processing step is simple, workable, to equipment without particular requirement, easily implements.
To achieve these goals, the present invention is by the following technical solutions:
A kind of high attachment automobile putty of the present invention, described height attachment automobile putty is made up of the component of following weight part: 350 ~ 400 parts of high viscosity polyester resins, 10 ~ 20 parts of vulcabond, the shellac ethanolic soln of 50 ~ 100 parts of 20 ~ 30wt%, 5 ~ 10 parts of Nano metal powders, 5 ~ 10 parts of Stearyl mercaptans, 50 ~ 80 parts of nano kaolines, 10 ~ 20 parts of magnesium oxide, 20 ~ 30 parts of magnesium chlorides, 10 ~ 20 parts of basalt fibres, 5 ~ 10 parts of Sodium Fluorides, 20 ~ 30 parts of vinylbenzene, 100 ~ 150 parts of talcum powder, 50 ~ 60 parts of titanium dioxides, 5 ~ 10 parts of cobalt octoates, 200 ~ 250 parts of cyclohexanone peroxides.The invention provides a kind of high attachment automobile putty, wherein high viscosity polyester resin is self-control, relative to the resin such as Pneumoperitoneum pressure resin of routine, has better quick-drying and cohesiveness, to ground, particularly metal substrate and priming paint have good sticking power, vulcabond and high viscosity polyester resin synergy, can further improve the adhesive property of the present invention to ground, containing shellac in shellac ethanolic soln, shellac clinging power is strong, and has acidproof, corrosion-resistant, resistance to wet goods characteristic, and can greatly improve the over-all propertieies such as cohesiveness of the present invention and toughness, in addition, the shellac coefficient of expansion is little, can reduce the contraction that rear generation is solidified in the present invention, Nano metal powder has excellent heat conductivility, energy flash heat transfer, reduce thermograde, the temperature at the present invention inside and outside each position when solidifying can be consistent, thus the solidification rate at each position of putty is consistent, ensure the surface effect repaired, in addition, Nano metal powder can form cross-linking set in resin, thus improve the resistance to impact shock of putty of the present invention, but Nano metal powder dispersion effect is poor, and greatly can affect the sticking power of the present invention at bodywork surface, reduce the cohesive force between putty and ground, putty is easily thrown off, and in order to solve the problem, contriver adds Stearyl mercaptan and Sodium Fluoride in putty, Stearyl mercaptan has surface-active action, Nano metal powder can be made dispersed, Stearyl mercaptan energy stable curing system and control solidification rate simultaneously, avoid affecting construction operation time because solidifying too fast, improve workability, the susceptibility of solidification rate to temperature can also be reduced, the present invention can be solidified in the temperature range of-10 ~ 30 DEG C, and Sodium Fluoride has the effect of microcorrosion, the contact surface of putty and vehicle body can be made to form hair side, thus improve the contact area of putty and vehicle body, greatly improve the sticking power of putty, putty and vehicle body are combined closely not easily throw off, avoid collapsing block phenomenon to produce, improve shock resistance, nano kaoline makes appearance uniform of the present invention, fine and smooth, and is easy to polishing, adopts water mill, dry grinding, sagging phenomenon is easily there is in putty in construction process, cause upper-thin-lower-thick, therefore magnesium oxide is added in the present invention to increase the force of cohesion of putty, no longer flow after putty blade coating is shaped, and do not adhere to scraper, but magnesian addition is excessive, putty grinability can be affected, addition is little, then inoperative, therefore must strictly control its addition, magnesium chloride can make the putty after solidification very fine and closely woven, bubble-free and sand holes, and makes polishing rear surface highly polished, basalt fibre can improve intensity and the snappiness of putty, and the volumetric shrinkage after simultaneously effectively suppressing putty to solidify, avoids putty surface cracking, vinylbenzene is linking agent, reticulated structure can be cross-linked into molecular resin chain when solidifying, also play the effect of thinner, make putty have certain denseness, but cinnamic add-on can affect curing speed and grinability, add-on is too many, the solidification of putty difficulty, very little, difficult polishing, therefore must strictly limit its add-on to add-on, talcum powder and titanium dioxide are filler, both synergys, and grinability is good, cobalt octoate is promotor, shortens resin curing time, cyclohexanone peroxide is solidifying agent.Height attachment
