Abstract

An air-drying unsaturated polyester resin for putty is prepared from ordinary chemical raw materials without air-drying groups. The excellent formula is that raw materials such as phthalic anhydride, maleic anhydride, diethylene glycol, glycerol, isooctanoic acid, styrene and the like are sequentially added into a reaction kettle, the raw materials are uniformly stirred and reacted at a certain temperature, and a proper amount of stannous octoate is added as a catalyst, so that the novel special air polyester resin for the putty, which is free of wax, good in air-drying property and capable of achieving various properties, part of the properties of the novel special air polyester resin exceed those of expensive allyl ether modified unsaturated resin, the production cost of the novel special air polyester resin is equivalent to that of dry oil modified unsaturated resin, even slightly lower, and the cost performance is excellent, can be prepared.

Description

A kind of air-dried unsaturated polyester resin for putty
The present invention relates to the homopolymer of a plurality of unsaturated aliphatic based compounds and the coating composition of multipolymer, belong to a kind of vibrin of putty special use, particularly a kind of air-dried unsaturated polyester resin for putty.
Ideal putty should have good air-drying property, excellent grinability, firm sticking power and snappiness, blade coating, impact resistance, thermotolerance, package stability etc., and requires low, the high efficiency of cost.Wherein the air-drying property of resin is the most basic problem.For guaranteeing that resin has good air-drying property, technical measures that adopted traditionally, generally all be to introduce the air-drying property group in resin, for example allyl ether series, dryness oils (tung oil, flax wet goods), dicyclo are defended diene, tetrahydrophthalic anhydride, m-phthalic acid or the like.The unsaturated polyester resin of putty special use at present has two classes, is to use the allyl ethers modified unsaturated resin mostly in developed country.Though this resinoid over-all properties is good, but, caused the cost performance of resin low because allyl ethers costs an arm and a leg, nocompetitive on market, can only be used on the high-grade goods; Another kind of is the siccative oil modified unsaturated resin, and siccative oil is cheap, and the production cost of this class unsaturated polyester is lower naturally, but because the birth defects of siccative oil cause this resinoid The comprehensive performance relatively poor again, can only be used on the low grade products.
The objective of the invention is provides a kind of common raw material that does not conform to the air-drying property group just producible to the public, performance can reach and the part characteristic also can surpass the allyl ethers modified unsaturated resin, and production cost and siccative oil modified unsaturated resin are quite or lower air-dried unsaturated polyester resin for putty.
The major technique feature of the air-dried unsaturated polyester resin for putty that the invention technology is produced just is: it is formed by the preparation of raw material that does not contain the air-drying property group,
Its prescription is: (in the summation of quality be 100 degree)
Phthalic anhydride 13.00-13.20, cis-butenedioic anhydride 8.50-8.74, glycol ether 10.40-10.50, glycerine 8.2-8.30, isocaprylic acid 12.84-12.90, all the other are vinylbenzene.
Its production technique is: phthalic anhydride, glycol ether and glycerine are placed by the proportional of prescription to add gentle stirring in the reactor gradually earlier, when temperature in the kettle is raised to 200-220 ℃, percent 0.2 the stannous octoate that adds quality again gradually and be raw materials quality sum in the still is made catalyzer and continues to stir, add cis-butenedioic anhydride and isocaprylic acid by prescription again, continue to stir and gradually temperature in the kettle is risen 240 ℃, the acid number for the treatment of material in the still is when 27-28, add vinylbenzene more gradually, stirring gets product.
The air-dried unsaturated polyester resin for putty that makes with the technology of the present invention, do not contain cured and air-drying property good, its every performance all can reach, and partial properties also surpassed the allyl ethers modified unsaturated resin, with its putty that modulates (atom ash) short texture, hard and soft suitable, air-drying property good, strong adhesion, easily polishing light and thermotolerance height, good impact resistance, package stability are lasting.The used raw material of the technology of the present invention is common industrial chemicals commonly used, purchase and cheap easily, and its production cost is suitable with the siccative oil modified unsaturated resin, even lower slightly, so its cost performance of product characteristic, traditional used product can't be compared at all.
When implementing the technology of the present invention, must be incremental to the temperature of reactor heating, fierce intensification that can't great-jump-forward.Quantitative used glycerine can be once to add when just beginning in the prescription, also can be to add 1/2-2/3 earlier when just beginning, and remaining part all adds when adding cis-butenedioic anhydride and isocaprylic acid again.
