Abstract
The invention discloses a kind of middle-size and small-size steel-casting alkyd resins.Described its raw material of steel-casting alkyd resin includes: soya-bean oil, tung oil, anti-skinning agent, catalyst, composite drier, hard promotor and other compounds thoroughly.Casting is with alkyd resin because it is different from the synthesis technology of furan resin for casting, and it uses the raw material of environmentally friendly, and the substance being harmful to the human body in product without free formaldehyde, free phenol etc. will gradually substitute furane resins in the application of casting field.The present invention overcomes the shortcomings of the prior art, and by technological innovation, what be successfully developed that a kind of viscosity is low, the up time is short, can be realized quickly whole hardening, collapsibility and work well is suitble to middle-size and small-size steel-casting alkyd resin.
Description
Technical field
The invention belongs to cast auxiliary material technical field, and in particular to a kind of viscosity is low, setting rate is fast, it is whole hard to can be achieved
Change, is suitable for middle-size and small-size steel-casting alkyd resin and preparation method thereof.
Background technique
Nineteen twenty-seven, the polyester that the Kienle of General Electric Co. Limited synthesizes polyalcohol with polyacid have made great improvement,
Fatty acid is added in the ingredient of polyester, the phthalic acid glyceride containing unsaturated fatty acid is developed, based on it by pure and mild acid
Synthesis, therefore this polymer is referred to as " alkyd ".After alkyd mass industrial applications, promotes answer in coatings industry always
With not promoted on a large scale in casting industry.To find out its cause, on the one hand be domestic technique technological reserve it is not perfect,
At the scene in use process, lack the technological guidance of profession；On the other hand, as the development of domestic foundry industry is getting faster, institute
Small but excellent state is presented in the casting of generation, and middle-size and small-size steel-casting is required to realize whole quick-hardening in modeling process,
Promote working efficiency.So far from 2016, the continuous 3 years implementation winter heating season industrial enterprises in China urban avoid the peak hour production,
Thousands of foundry enterprises has met with halt production or limited production because of the problems such as environmental protection or safety supervision.Under new Environmental Protection Situation, China's casting
It makes enterprisers and is used as cardinal task to grab environmentally friendly, safety is carried out, and has started environmental protection, a safety in Chinese Foundry industry
Upgrading upsurge.Casting is with alkyd resin because it is different from the synthesis technology of furan resin for casting, and its use is to environment
The raw material of friendly, the substance being harmful to the human body in product without free formaldehyde, free phenol etc., will gradually substitute furans tree
Application of the rouge in casting field.
Summary of the invention
The present invention is in view of the deficienciess of the prior art, provide a kind of middle-size and small-size steel-casting alkyd resin and its preparation side
Method successfully realizes that viscosity is low, the up time is short, quick entirety is hardened, collapsibility works well by technological innovation.
A kind of middle-size and small-size steel-casting alkyd resin, raw material includes: soya-bean oil, tung oil, anti-skinning agent, catalyst, compound
Drier, hard promotor and other compounds thoroughly.
Further, the mass percentage of the soya-bean oil is 10%-16%.
Further, the mass percentage of the tung oil is 20%-28%.
Further, the hard promotor thoroughly is the one or more of KH560, KH550, KH602；The hard saturating promotor
Mass percentage be 0.5%-1.5%.
Further, the catalyst be lithium hydroxide, barium hydroxide, calcium oxide and calcium hydroxide aqueous solution in extremely
Few one kind；The mass percentage of the catalyst is 0.5%-1.5%.
Further, the composite drier is cobalt iso-octoate, manganese iso-octoate, isooctyl acid lead, zinc Isoocatanoate, isooctyl acid

Further, the anti-skinning agent is or mixtures thereof cyclohexanone oxime, turpentine oil, dipentene, butyl aldoxime；It is described anti-
The mass percentage of crust forming agent is 1.5%-2.5%.
The beneficial effects of the present invention are:
(1) process resin by technological innovation and selects suitable raw material, the alkyd resin viscosity produced using new process
At 150mpa.s or so (25 DEG C), it is convenient for execute-in-place, mulling is uniform.
(2) it is added to suitable hard saturating promotor in the process resin, the whole hardening of sand mold can be effectively facilitated, it is traditional
Large-scale steel-casting, in 10min or more, seriously constrains the production efficiency of middle-size and small-size steel-casting with the alkyd resin up time, should
The resin of technique production, up time control substantially increase the operating efficiency at scene in 5min or so.
(3) China continuously increased the environmentally friendly supervision dynamics to casting industry in recent years, this technique is choosing synthesis former material
When material, environment amenable raw material are had chosen, without free phenol, free formaldehyde, the ammonia occurred in furane resins in the product
Water, methanol, acetone etc. have fundamentally prevented the product to the danger of environment and human body to human body and the great ingredient of environmental hazard
Evil, belongs to environmentally friendly machine.
