Description

The atom ash

Technical field:

The present invention relates to chemical industry class coating, particularly relate to the atom ash that is used for lathe, car surface linging.

Background technology:

At present, automobile, atom ash commonly used was as packing material before metallic surface or wood surface were sprayed paint in lathe and other manufacturing, but because the atom ash solidifies slowly, poor adhesive force, difficult polishing, should chap, be subjected to that thereby the variation of wetness has influenced the quality and the efficient of spraying paint in the environment, for addressing the above problem, patent application publication number is that the major ingredient of atom ash is a unsaturated polyester in the patent application of CN1097200 disclosed " prescription of atomic lime putty ", vinylbenzene, methacrylic acid-β-Xiang second fat, N, the N xylidene(s), Resorcinol, phenylformic acid, bitter edible plant acid cobalt, talcum powder and titanium dioxide, because cinnamic consumption is big in its prescription, the solid relative content is low, cause atom ash poor adhesive force, difficult polishing, easily be full of cracks, though have quick solidifying, the advantage of good weatherability, but be prone to be full of cracks, peeling, the phenomenon of bubbling influences the result of use and the visual appearance of product.

Summary of the invention:

The purpose of this invention is to provide that the fast and strong adhesion of a kind of not only rate of drying, easily polishing, smooth finish are good, good weatherability, long atom ash of shelf-time.

The objective of the invention is to realize by following technical scheme:

A kind of atom ash, be mixed in proportion formulated by host and solidifying agent, described solidifying agent is made up of cyclohexanone peroxide, dibutyl phthalate (DBP), gas phase level white carbon black, wherein gas phase level white carbon black accounts for the 10%-12% of solidifying agent gross weight, all the other are cyclohexanone peroxide and dibutyl phthalate (DBP), and the ratio of the two is 1: 0.8-1: 1.2; The weight ratio of host and solidifying agent is 100: 2-100: 2.5; Wherein each component and content thereof with weight part are in the host:

Unsaturated polyester 100 vinylbenzene 5-17 talcum powder 130-195 ultramarine 0.02-1

Lithopone and/or titanium dioxide 1-3 active silica 2-6 cobalt iso-octoate 1.5-3.5

T-butyl catechol 0.01-0.5 N, accelerine 0.125-0.3

Each component and content thereof with weight part are in the preferred host:

Unsaturated polyester 100 vinylbenzene 8-15 talcum powder 140-190 ultramarine 0.02-1

Lithopone and/or titanium dioxide 2-3 active silica 3-6 cobalt iso-octoate 1.5-2.5

T-butyl catechol 0.02-0.3 N, accelerine 0.15-0.3

More preferably each component and content thereof with weight part are in the host:

Unsaturated polyester 100 vinylbenzene 10-13 talcum powder 150-160 ultramarine 0.02-0.075

Lithopone and/or titanium dioxide 2.2-2.6 active silica 3-4 cobalt iso-octoate 2-2.5

T-butyl catechol 0.03-0.04 N, accelerine 0.2-0.3

Each component and content the best thereof with weight part are in the host:

Unsaturated polyester 100 talcum powder 130-150 lithopones and/or titanium dioxide 1-1.5

Active silica 2-4 cobalt iso-octoate 1.5-2 t-butyl catechol 0.01-0.02

N, accelerine 0.2-0.3 ultramarine 0.02-0.075

Low and the cobalt iso-octoate wherein of styrene content has the effect that promotes reaction in the component that the present invention adopts, therefore not only rate of drying is fast for atom ash of the present invention, and strong adhesion, surface drying, no thickness sense, the polishing performance is good, thixotropy is good, weather resisteant, stability all improves a lot, the polishing time was 25min-30min when it was 25 ℃ in envrionment temperature, sticking power is the I level, gelation time is 3-5min, good hand touch during blade coating, dry back flawless, do not come off, no sand holes, do not have and sting end phenomenon generation, it can be deposited when envrionment temperature is 20 ℃ 90 days-180 days; Atom ash of the present invention also has the characteristics of the little or non-environmental-pollution of environmental pollution.

Embodiment:

Atom ash of the present invention by host and solidifying agent according to a conventional method mixed preparing form, described solidifying agent is made up of cyclohexanone peroxide, dibutyl phthalate (DBP), gas phase level white carbon black, wherein gas phase level white carbon black accounts for the 10%-12% of solidifying agent gross weight, all the other are cyclohexanone peroxide and dibutyl phthalate (DBP), and the ratio of the two is 1: 0.8-1: 1.2; The weight ratio of described host and solidifying agent is 100: 2-100: 2.5; Each component and content thereof with weight part are in the described host: 100 parts of unsaturated polyesters, vinylbenzene 5-17 part, talcum powder 130-195 part, lithopone and/or titanium dioxide 1-3 part, active silica 2-8 part, cobalt iso-octoate 1.5-3.5 part, ultramarine 0.02-1 part, t-butyl catechol 0.01-0.5 part, N, accelerine 0.125-0.3 part;

The each component preferred content with weight part is in the host: 100 parts of unsaturated polyesters, vinylbenzene 8-15 part, talcum powder 140-190 part, lithopone and/or titanium dioxide 2-3 part, active silica 3-6 part, cobalt iso-octoate 1.5-2.5 part, ultramarine 0.02-1 part, t-butyl catechol 0.02-0.3 part, N, accelerine 0.15-0.3 part;

The more preferably content of each component with weight part is in the host: 100 parts of unsaturated polyesters, vinylbenzene 10-13 part, talcum powder 150-160 part, lithopone and/or titanium dioxide 2.2-2.6 part, active silica 3-4 part, cobalt iso-octoate 2-2.5 part, ultramarine 0.02-0.075 part, t-butyl catechol 0.03-0.04 part, N, accelerine 0.2-0.3 part;

The optimum content of each component with weight part is in the host: 100 parts of unsaturated polyesters, talcum powder 130-150 part, lithopone and/or titanium dioxide 1-1.5 part, active silica 2-4 part, cobalt iso-octoate 1.5-2 part, t-butyl catechol 0.01-0.02 part, N, accelerine 0.2-0.3 part, ultramarine 0.02-0.075 part, because of in this scheme, not containing vinylbenzene, therefore can not pollute environment, be a kind of atom ash of environment-friendly type.

In the above-mentioned prescription, between lithopone and titanium dioxide, preferentially select lithopone for use, not only can increase atom ash toughness with it, make the blade coating enhancing of atom ash, and since the unit price of lithopone far below titanium dioxide, therefore, can reduce the cost of atom ash, the adding of silicon-dioxide mainly is in order to increase the viscosity of atom ash, to increase the thixotropy of atom ash, playing anti-settling simultaneously, after adding t-butyl catechol, make the period of storage of atom ash can reach 90 days-180 days under 20 ℃ envrionment temperature, different Rinmann's green as reaction promotor, improves speed of response at this, make the atom ash have surface drying, the characteristics of no thickness sense, therefore, grinability is good, thixotropy is good, can make the host that makes manifest light gray behind the adding ultramarine.

Atom ash of the present invention prepares according to a conventional method, be specially unsaturated polyester is poured in the container, add cobalt iso-octoate, N then successively, after accelerine, t-butyl catechol, vinylbenzene, titanium dioxide and/or lithopone, active silica, ultramarine stir, drop into talcum powder, stirred once more 1-2 hour, then carrying out 2-3 time grinds, drop into once more and carry out secondary stirring in the container, the time is 2 hours, and the host finished product that makes light grey paste/pasty state is standby; Grind after gas phase level white carbon black stirs stirring in dibutyl phthalate (DBP) and the cyclohexanone peroxide input container, adding, it is standby to make solidifying agent in the sealed vessel of packing into; During use with host and solidifying agent by 100: 2-100: 2.5 part by weight mixes and gets final product.It is widely used on automobile making and repairing, boats and ships, locomotive, high-grade furniture and the household electronic products.
