Abstract
Natural shellac is processed through the processes of milling into 50-200 mesh powder, soaking treatment in hydrogen peroxide liquid of 10-100 ml for each 10 g shellac inside one sealed container at 10-80 deg.c for 4-300 hr, taken out of the container and air dried to obtain red or color-less shellac paint.
Description
The present invention relates to a kind of production method of shellac varnish, this method can change the color of lacquer.
Common coating agent which has to be dissolved in alcohol before use is called shellac varnish again, and this coating agent which has to be dissolved in alcohol before use has two kinds of colors usually, and a kind of is that common shellac varnish is dark-brown.Another kind is a high-grade shellac varnish comparatively, is light brown.These two kinds of shellac varnishes all are raw natural shellac varnishes, and this lacquer has following defective: the paint film quality is hard and crisp, poor adhesive force, and transparency is low, and the glossiness of coating surface is low, easily bursts behind the drying varniss.In addition, because natural shellac varnish has darker color, can only decorate dark colour furniture, thereby limit the use range of shellac varnish.Therefore, need change the performance of natural shellac varnish, overcome the defective of natural shellac varnish by certain processing means.
The production method that the purpose of this invention is to provide a kind of shellac varnish, the modification shellac varnish that this method is produced can overcome above-mentioned deficiency.
The objective of the invention is to realize: dark-brown natural shellac varnish is milled into 50-200 purpose powder by following technical proposals, with the shellac varnish powder with put into airtight Glass Containers after hydrogen peroxide liquid is mixed and carry out dip treating, per 10 gram shellac varnish powder 10 milliliters of-100 milliliters of hydrogen peroxide liquid that are mixed, the temperature of this dip treating remains on 10 ℃-80 ℃, the time of dip treating is 4-300 hour, after dip treating finishes shellac varnish is taken out to dry promptly to can be made into red shellac varnish.
Compared with the prior art the present invention has following advantage:
1, its paint film lovely luster of shellac varnish made from the present invention is difficult for fading, and promptly can make colored shellac varnish, also can make water white shellac varnish;
2, its paint film good springiness of shellac varnish made from the present invention is difficult for bursting durable;
3, the surface gloss height of its paint film of shellac varnish made from the present invention, paint film transparency height.
The invention will be further described below in conjunction with embodiment.
Embodiment one:
Present embodiment is the production method of red shellac varnish, dark-brown natural shellac varnish is milled into 200 purpose powder, then with this shellac varnish powder with put into airtight Glass Containers after hydrogen peroxide liquid is mixed and carry out dip treating, per 10 gram shellac varnish powder 10 milliliters of-100 milliliters of hydrogen peroxide liquid that are mixed, the temperature of this dip treating remains on 10 ℃-80 ℃, optimum temps is 20 ℃, the time of dip treating is 4-300 hour, Best Times is 248 hours, after dip treating finishes shellac varnish is taken out to dry promptly to can be made into red shellac varnish.The mode flash baking that also can adopt oven dry to handle.The shellac varnish made from present embodiment is the same with the using method of natural shellac varnish, does not describe one by one at this.
Embodiment two:
Present embodiment is the production method of yellow shellac varnish, the senior shellac varnish of light brown is milled into 100 purpose powder, with the shellac varnish powder with put into airtight Glass Containers after hydrogen peroxide liquid is mixed and carry out dip treating, per 10 gram shellac varnish powder 10 milliliters of-100 milliliters of hydrogen peroxide liquid that are mixed, the temperature of this dip treating remains on 10 ℃-80 ℃, optimum temps is 20 ℃, the time of dip treating is 4-300 hour, Best Times is 124 hours, after dip treating finishes shellac varnish is taken out to dry promptly to can be made into yellow shellac varnish.
Embodiment three:
Present embodiment is the production method of colourless shellac varnish, the yellow shellac varnish that uses aforesaid method to make is dissolved in the alcohol liquid, make the shellac varnish lysate, per 50 gram shellac varnishes are joined the 100-500 ml ethanol, described ethanol concn is 95%, in described lysate, be blended into 1-3 condensing agent chlorine water doubly then, be that the described lysate of per 100 grams is blended into 100 grams-300 gram chlorine waters, the best is blended into 200 gram chlorine waters, treat to take out after described shellac varnish condenses, be milled into 100 purpose powder then, with this shellac varnish powder with put into airtight Glass Containers after hydrogen peroxide liquid is mixed and carry out dip treating, per 100 gram shellac varnish powder 100 milliliters of hydrogen peroxide liquid that are mixed, the temperature of this dip treating remains on 20 ℃, the time of dip treating is 248 hours, after dip treating finishes shellac varnish is taken out to dry promptly to can be made into colourless shellac varnish.
Embodiment four:
Present embodiment is the production method that the color with common shellac varnish and above-mentioned red shellac varnish shoals, common shellac varnish and red shellac varnish are dissolved in the alcohol liquid, make the shellac varnish lysate, per 50 gram shellac varnishes are joined the 50-1000 ml ethanol, described ethanol concn is 95%, in described lysate, be blended into 0.5-3 condensing agent chlorine water doubly then, be that the described lysate of per 100 grams is blended into 50 grams-300 gram chlorine waters, the best is blended into 200 gram chlorine waters, treat to take out after described shellac varnish condenses, be milled into 100 purpose powder then, with this shellac varnish powder with put into airtight Glass Containers after hydrogen peroxide liquid is mixed and carry out dip treating, per 100 gram shellac varnish powder 50 milliliters of-1000 milliliters of hydrogen peroxide liquid that are mixed, the temperature of this dip treating remains on 20 ℃, the time of dip treating is 248 hours, after dip treating finishes shellac varnish is taken out to dry promptly to can be made into the orange shellac lacquer.Above-mentioned making processes is repeated repeatedly, promptly can be made into the more shallow or colourless shellac varnish of color.
