Description
Technical field
The invention belongs to Polymer materialspreparation and construction and application technique field, especially relate to unsaturated resin coating encapsulant and the using method of a kind of energy rapid construction.
Background technology
Unsaturated polyester is the product by saturated or undersaturated polyprotonic acid or acid anhydrides and polyvalent alcohol polycondensation, evenly mixes with reactive solvents and makes, and is to use and a kind of coating film forming matter widely.The anticorrosive coating system often uses unsaturated polyester coating to be used for being coated with or face is coated with, the industrial paints such as woodenware also often use unsaturated polyester coating as the high light coating in top layer, field of wind power generation, use unsaturated polyester to make the products such as gel coat, be used for the finish paint of product surfaces externally and internally, play protective effect.
Unsaturated resin coating is to rely on the oxyradical that peroxide firming agent provides and the system Raolical polymerizable that causes reaches the purpose of film-forming.In solidification process, airborne oxygen can have to the polyreaction of top layer resin certain inhibition, does not do so the surface often appears in unsaturated resin coating, be clamminess, surface and bottom be the situation such as simultaneously curings not, causes the decline of coating gloss, strength decreased is easy to the shortcomings such as destruction.
Traditional constructional method is to add the materials such as paraffin, tung oil in unsaturated polyester coating, and when treating coating curing, these materials can be distributed to the isolated coating of coating surface and air, reach the purpose that assisted gas is done.But the unsaturated resin coating of the materials such as interpolation paraffin, surface gloss significantly reduces, and needs manual polishing and polishing just can reach higher brightness, has limited the Application Areas of unsaturated polyester.Commercially available also have the gas take trimethylolpropane allyl ether as main component to do agent, and adding can assist the gas of unsaturated polyester to do; But this additive is expensive, is difficult to spread.
Along with the development of technology, increasing air-drying property unsaturated polyester is developed.The air drying type paint mixture that comprises the carbohydrate-based polyester among the patent documentation CN1643029; Be the acyl ester that uses carbohydrate, with unsaturated polyester raw material hybrid reactions such as polyvalent alcohol, polyprotonic acids, possess preferably air-drying property energy.Patent documentation CN101805430 provides a kind of air-drying chemical corrosion resistant unsaturated resin and production technique thereof; Use gas butt group that the hosts such as agent, bridging agent, catalyzer, linking agent and stopper are provided, be applied in the building-up reactions of traditional unsaturated polyester, the air-drying property unsaturated polyester that obtains is functional.Patent documentation CN102443114 provides air-dried unsaturated polyester resin of a kind of excellent combination property and preparation method thereof; Selecting renewable Vegetable oil lipoprotein is that raw material carries out the synthetic of unsaturated polyester, low-carbon environment-friendly, and cheap, air-drying property is relatively good.Patent documentation CN102453247, patent documentation CN101565493, patent documentation CN102766237, patent documentation CN1325914 etc. use different assisted gas to do component to participate in the building-up reactions of unsaturated polyester, reach the purpose that the resin air-drying property improves.But these air drying type unsaturated polyesters are all developed specially for a certain special dimension, and the unsaturated polyester more traditional except price lacks the market competition advantage, also do not possess versatility.In the occasion that general unsaturated polyester can meet the demands, do the purpose occasion as long as can just can reach gas by speedy construction method, these special resins with the dried characteristic of gas are difficult to be widely used.
