Description

A kind of making method of green paint

Technical field

The invention belongs to building coating.

Technical background

Charcoal be timber or wood material through incomplete combustion, perhaps pyrolysis under the condition of secluding air, residual Vandyke brown or black porosu solid fuel.Be the impure decolorizing carbon that keeps residual tar in original structure of timber and the hole.Charcoal is all used in the bronze work of China's Shang dynasty and the smelting of period in Spring and Autumn and Warring States's epoch ironware, utilizes its water absorbability to observe climate change etc.Except that still doing the life fuel, also be used as the fuel of Metal smelting, food and light industry now, the reductive agent of electrosmelting, not oxidized when metal is refining as insulating covering agent protection metal.On chemical industry, often make the raw material of dithiocarbonic anhydride and gac etc.In addition in application of aspects such as grinding, drawing, cosmetic, medicine, gunpowder, carburizing, powder metallurgies.Raw material by the usefulness of making charcoal can be divided into: 1. hard wealthy charcoal.By hard pourous wood such as Fagaceae Quercus acutissima belong to, the Castanopsis trees are main, accessory also have Betula etc.2. broad-leaved charcoal.Charcoal by hard, soft pourous wood mixed sintering.3. pine charcoal.The charcoal of firing by pine or other softwoods.Bamboo charcoal that useful in addition bamboo class is fired and the fruit stone charcoal of firing with shell, fruit stone wood materials such as (Exocarpium cocois (Cocos nucifera L), peach-pits).The faggot and charcoal of collecting from home furnace then is commonly called as the small wooden raft charcoal.After charcoal is pulverized, mix, carry out hematocrit moulding and roasting again and then make the hematocrit charcoal with suitable adhesive.Divide hard charcoal and black wood charcoal by the technology of making charcoal.The charcoal main component is a carbon, also has hydrogen, oxygen, nitrogen and a spot of other elements in addition, and the relation of its content and seeds is little, depends primarily on the outlet temperature of charing.Charcoal belongs to the hydrophobic nature material, ash oontent is in 6%, hole accounts for the charcoal volume more than 7%, proportion is generally 1.3～1.4, thermal value depends on carbonization condition, generally about 8000 kcal/kg, the reducing power of charcoal is greater than coke, thereby as the reductive agent and the insulating covering agent of Metal smelting.Charcoal has a large amount of micropores and transitional pore, makes it that higher specific surface area not only be arranged, and after tar material is excluded in the hole good attraction performance will be arranged, so be the important source material of preparation gac.People's charcoal heating commonly used, fuel, particularly machine-made charcoal that barbecue, chafing dish are used, because its no smoke, thermal value is big, combustion time is long, so more and more be subjected to people's favor.Countless in length and breadth holes is arranged on the charcoal, and the function that these holes have the various materials of absorption and put out the material that is adsorbing is so people make dehumidizier with it.When humidity, charcoal can absorb moisture, and in the time of exsiccant, its can provide the humidity that has absorbed out, thereby the effect of humidity is regulated in performance with flying colors.In addition, charcoal can also be eliminated smell in the room and objectionable impurities etc.Present spread coated paint for building (having another name called putty) comprises interior wall and exterior coating, usually uses after the putty levelling material as the look face.Putty polyvinyl alcohol glue commonly used and filler are made.Finishing in first procedure putty construction remakes coating application (two procedures), because material, foaming, delamination, not water-fast Xian, not durable etc. has been the knotty problem on the engineering.The invention provides a kind of green paint, this coating can overcome the deficiency of existing coating and putty function, but double as coating and putty use, can contemporaryly use again for coating and putty, it can change an operation into by former two operations and finish (having reduced by an operation), and its surface has weather resistance, water tolerance and the good effect of heat insulation that can not replace beautiful sense organ and material.When humidity, can absorb moisture, the exsiccant time, its can provide the humidity that has absorbed out, thus the effect of humidity is regulated in performance with flying colors.In addition, can also eliminate smell in the room and objectionable impurities etc.

Summary of the invention

Green paint of the present invention is made up of modified acroleic acid and silicon sol, and its prescription comprises: (weight) silicon sol 4-7%, modified acroleic acid 10-16%, Paris white 30-38%, wood charcoal powder 8-10%, conditioning agent fourth 5-6%, Phenol aldehyde resin 7 one 11%, talcum powder 20-26%.
