Abstract
The invention discloses a low-temperature fast-curing energy-saving type polyester resin which comprises the following raw materials in parts by weight: 20-28 of purified terephthalic acid, 8-15 of neopentyl glycol, 5-10 of cyclohexanedimethanol, 0.1-0.05 of trimethylolpropane, 0.1-0.02 of monobutyltin oxide, 0.01-0.05 of triphenyl phosphite, 0.05-0.15 of an antioxidant, 1-3 of adipic acid, 1-3 of benzene, and 0.2-0.5 of cetylbenzyl dimethyl ammonium bromide. The traditional curing condition of the polyester resin is 200 DEG C/10' or 190 DEG C/15', and the energy consumption is larger, while the low-temperature fast-curing energy-saving type polyester resin is cured at the low temperature of 160 DEG C/10' or 140 DEG C/25', thereby greatly reducing the energy consumption, being energy-saving and consumption-reducing, and better improving the labor productivity and increasing economic benefits.
Description
Technical field
The present invention relates generally to a kind of energy-saving vibrin, relates in particular to the energy-saving vibrin of a kind of low temperature fast setting.
Background technology
The general name of the macromolecular compound that vibrin is formed by dibasic alcohol or diprotic acid or polyvalent alcohol and polyprotonic acid polycondensation.Vibrin is to be divided into saturated polyester resin and unsaturated polyester resin.The unsaturated polyester tackiness agent mainly is comprised of auxiliary agents such as unsaturated polyester resin, color stuffing, initiators.Tackiness agent viscosity is little, easy wetting, good manufacturability, but the glue-line hardness after curing is large, the transparency is good, the high room temperature pressurization of luminance brightness fast setting, thermotolerance are better, and electrical property is good.Shortcoming is that shrinking percentage is large, gluing toughness is not high, and resistant to chemical media and water tolerance are relatively poor, is used for non-sqtructural adhesive.Be mainly used in gluing glass reinforced plastic, rigid plastics, concrete, electric potting etc.
Traditional curable polyester resin condition is 200 ℃/10 ', or 190 ℃/15 ', power consumption is larger like this.
Summary of the invention
The object of the invention is exactly in order to make up the defective of prior art, to provide a kind of low temperature fast setting energy-saving vibrin.
The present invention is achieved by the following technical solutions:
The energy-saving vibrin of a kind of low temperature fast setting, it is comprised of the raw material of following weight parts:
Pure terephthalic acid 20-28, neopentyl glycol 8-15, cyclohexane dimethanol 5-10, TriMethylolPropane(TMP) 0.1-0.05, Mono-n-butyltin 0.1-0.02, triphenyl phosphite 0.01-0.05, oxidation inhibitor 0.05-0.15, hexanodioic acid 1-3, benzene 1-3, hexadecyl quaternary amine 0.2-0.5.
The preparation method of the energy-saving vibrin of described low temperature fast setting is:
(1) esterification: with the pure terephthalic acid of above-mentioned weight part, neopentyl glycol, cyclohexane dimethanol, TriMethylolPropane(TMP), Mono-n-butyltin are blended in and carry out esterification under 230-250 ℃, and the reaction times is 9-11 hour;
(2) acidolysis: add the triphenyl phosphite oxidation inhibitor of above-mentioned weight part in reactant of esterification obtained above, hexanodioic acid, benzene carried out under 215-225 ℃ acidolysis 3-4 hour;
(3) negative pressure: after acidolysis is completed, by negative pressure 2-3 hour, then add the hexadecyl quaternary amine of above-mentioned weight part, stir, namely get the energy-saving vibrin of described low temperature fast setting.
Advantage of the present invention is:
The traditional condition of cure of vibrin is 200 ℃/10 ', or 190 ℃/15 ', power consumption is larger like this, and of the present inventionly be 160 ℃/10 ' or 140 ℃/25 ' low-temperature curing, so greatly reduce energy consumption, energy-saving and cost-reducing, better raise labour productivity and economic benefit.
