Abstract
The invention relates to an alkaline phenolic resin organic ester curing agent suitable for winter, which is characterized by comprising the following components in portions by weight: 600-700 portions of gamma-butyrolactone, 50-100 portions of carbonic ester compounds, 200-300 portions of acetic ester compounds and 10-20 portions of curing catalyst. The organic ester curing agent has the advantages of high curing strength and good mechanical properties, and can be used at lower temperature in winter, thereby effectively solving the problem that northern foundry enterprises use ohenolic resin for production in winter.
Description
Technical field
The present invention relates to a kind of organic ester curing agent, particularly relate to a kind of alkalescent phenol resin organic ester curing agent that is applicable to winter.
Background technology
The organic ester hardening alkaline phenolic resin self-hardening sand is a kind of advanced person's a formative technology, it mixes the back moulding with roughing sand, alkalescent phenol resin and organic ester curing agent, owing to do not contain elements such as N, S, P, therefore have characteristics such as the good and environmental pollution of casting quality is little.Owing to use at present organic ester curing agent, be difficult to use during less than 5 ℃ at temperature.Having limited organic ester hardening alkaline phenolic resin self-hardening sand technology uses in the production of north of china in winter.
Summary of the invention
The purpose of this invention is to provide a kind of a kind of alkalescent phenol resin organic ester curing agent of using under the colder situation of temperature of being adapted at, solidification effect is good.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of alkalescent phenol resin organic ester curing agent that is applicable to winter, it is characterized in that it is made up of in described weight portion ratio following compositions: 600～700 parts of gamma-butyrolactons, 50～100 parts of carbonats compounds, 200～300 parts of acetates compounds, 10～20 parts of curing catalysts.
Described carbonats compound is one or more compositions in dimethyl carbonate, diethyl carbonate, the diphenyl carbonate;
Described acetates compound is a kind of in methyl acetate, ethyl acetate, butyl acetate, acetic acid glycol ester, the acetoglyceride.
Described curing catalysts is a stannous chloride.
Compared with prior art, the invention has the beneficial effects as follows:
Alkalescent phenol resin organic ester curing agent of the present invention when using for-5 ℃ to-25 ℃, has very high mechanical performance as alkalescent phenol resin, efficiently solves northern enterprise uses machine ester sclerosis alkalescent phenol resin self-hardening sand technology during winter a difficult problem.
