Abstract
The invention discloses an aging resistant light extinction coating and a preparation method thereof, which belong to the technical field of macromolecular material utilization and coating, and, in particular relate to an aging resistant light extinction coating technology used in rubber boot surface and an improvement in the preparation method. The invention provides the aging resistant light extinction coating with excellent aging resistance and fluidity and a preparation process thereof. The rubber boot aging resistant light extinction coating is made from ethylene propylene rubber and silicon dioxide, and the preparation method comprises the following steps: 1, the following formula is adopted and includes: 100 portions of ethylene propylene rubber, 20 to 50 portions of silicon dioxide, 0.3 to 4.0 portions of vulcanizing agent, 2 to 15 portions of accelerant, 2 to 10 portions of activating agent, 0.5 to 5.5 portions of protection additive, less than 0.1 to 5 portions of dispersant, less than 0.1 to 5 portions of surface treatment agent, less than 0.1 to 5 portions of flatting agent and less than 1,000 to 4,500 portions of solvent; and 2, the materials in the formula are added in a grinding device for grinding, and the grinding time and dispersing process of silicon dioxide are controlled so that the silicon dioxide can be evenly dispersed; after grinding, the solvent is adopted to adjust the mixture to an appropriate concentration, and the aging resistant light extinction coating used in rubber boot can be obtained after filtration.
Description
Technical field:
The invention belongs to macromolecular material utilization and technical field of coatings, relate in particular to a kind of be applied in the anti-aging antiglossing pigment technology on rubber rain boots surface and preparation method's improvement.
Background technology:
In this year, along with improving constantly of people's living standard, human consumer's aesthetic standard is more and more tended to leisure, fashion and personalization, makes that the application of Flat paint is very extensive.Especially use the shared ratio of product of Flat paint also to improve year by year in the rubber rain boots industry, domestic employed Flat paint technology mainly contains two kinds at present: 1, the Flat paint made of adding matting agent such as the D-LAC HY-510, Korea Spro's home-made D-LAC HY-415 that produce of import base-material such as Japan or silicon-dioxide; 2, use the coating that is made as extinction materials such as base-material adding silicon-dioxide as the SBS thermoplastic elastic material.The 1st, because condition effect such as mechanism of import base-material own and curing temperatures, there is following shortcoming in the Flat paint after causing vulcanizing: the paint film ageing-resistant performance is bad; The coating surface flavescence is serious; The bad current mark that causes of coating flowing property is serious.The 2nd, also thoroughly do not solve for problems such as the dispersion of silicon-dioxide, sedimentations, and the ageing-resistant performance of this coating and flowing property are bad.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides that a kind of ageing-resistant performance is good, the anti-aging antiglossing pigment of good fluidity and preparation technology thereof.
For achieving the above object, the present invention adopts following technical scheme, and boot aging resistant light extinction coating of the present invention is made by ethylene-propylene rubber(EPR) and silicon-dioxide, and its preparation method may further comprise the steps:
1, be base mateiral with ethylene-propylene rubber(EPR) and silicon-dioxide, according to following prescription:
Ethylene-propylene rubber(EPR): 100 parts; Silicon-dioxide: 20-50 part; Vulcanizing agent: 0.3-4.0 part;
Promotor: 2-15 part; Promoting agent: 2-10 part; Aging aids: 0.5-5.5 part;
Dispersion agent:＜0.1-5 part; Surface treatment agent:＜0.1-5 part; Flow agent:＜0.1-5 part;
Solvent:＜1000-4500 part.
2, above-mentioned formula materials is joined in the milling apparatus grind, the milling time and the dispersing technology of control silicon-dioxide make it homodisperse, and ground back is used solvent to adjust to and promptly made the rubber rain boots anti-aging antiglossing pigment after suitable concentration is filtered.
Beneficial effect of the present invention:
1, the Flat paint ageing-resistant performance made from ethylene-propylene rubber(EPR) and silicon-dioxide is good, and crackle just appearred in 2-4 hour in the Flat paint that uses the allotment of import base-material under same experimental conditions under the sunlight direct projection; And Flat paint of the present invention trickle especially crackle just occurs reaching under the sunlight direct projection about 240 hours:
2, the Flat paint flowing property made from ethylene-propylene rubber(EPR) and silicon-dioxide number, current mark are slight, and do not have the flavescence phenomenon, thereby have improved product appearance quality and class:
3, Flat paint rational formulating of recipe of process and the technology controlling and process made from ethylene-propylene rubber(EPR) and silicon-dioxide, phenomenons such as no silicon-dioxide dispersion and sedimentation.
Embodiment:
