Abstract
The invention discloses a preparation method of a compound modified attapulgite alcohol-base foundry coating suspending agent. Attapulgite as a raw material is modified by using a compound modifying agent TM-MA to prepare the alcohol-base coating, and the alcohol-base coating has excellent thixotropy and 2h suspending rate of reaching 99 percent; the problem of dead precipitation of the attapulgite alcohol-base coating is solved. The coating is placed for a period of time in a sealing manner, and can be coated and brushed by slightly mixing; a coating layer automatically levels when being coated and brushed, can be dried in air, is smooth in surface after being dried, and is high in binding strength.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of preparation method of composite modified recessed native alcohol-base foundry coating suspending agent.
Background technology
Because traditional water based paint exists the shortcomings such as drying is slow, the production cycle is long, energy resource consumption is large, research and the use of alcohol-base foundry coating are just increasingly extensive.Recessed soil good dispersion in water, but when being applied in alcohol-base paint, be subject to a definite limitation, there is two problems: one is that suspension is bad in ethanol; Two is that the alcohol-base paint made easily hardens formation " silent as the grave shallow lake " in long-term storage process.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide a kind of preparation method of composite modified recessed native alcohol-base foundry coating suspending agent, obtained alcohol-base paint thixotropy is good, suspendability is superior, and the binding strength of coating of coating is high, fine and close, smooth.
The preparation method of composite modified recessed native alcohol-base foundry coating suspending agent provided by the invention, comprises the following steps:
(1) with the recessed soil of 300 ~ 400 height of eye quality for raw material, appropriate TM-MA complex reagent and appropriate alcohol are mixed uniformly;
(2) add 5 ~ 10 grams of recessed soil, this sample is put in supersonic generator, stir and fully vibration;
(3) filter after placing a period of time, 60 ~ 80 DEG C of oven dry, obtain the composite modified attapulgite suspending agent of TM-MA.
The preparation method of composite modified recessed native alcohol-base foundry coating suspending agent provided by the invention, its beneficial effect is, add in coating through TM-MA modification recurve soil with the amount of 5 ~ 8 (aggregate is for 100), obtained alcohol-base paint thixotropy is excellent, 2h suspensibility reaches 99%, solves the dead sedimentation problem of recessed native alcohol-base paint.A period of time is placed in the sealing of this coating, stirs a little and can brush, and coating automatic levelling during brushing, in atmosphere can be dry, dry rear surface is smooth, and adhesion strength is high.
Detailed description of the invention
Below in conjunction with an embodiment, the preparation method of composite modified recessed native alcohol-base foundry coating suspending agent provided by the invention is described in detail.
Embodiment
The preparation method of the composite modified recessed native alcohol-base foundry coating suspending agent of the present embodiment, comprises the following steps:
(1) with the recessed soil of 400 height of eye quality for raw material, the TM-MA complex reagent of 5mL and appropriate alcohol are mixed uniformly;
(2) add the recessed soil of 5g, this sample is put in supersonic generator, stir and fully vibration;
(3) filter after placing a period of time, 70 DEG C of oven dry, obtain the composite modified attapulgite suspending agent of TM-MA.
Claims (1)
1. a preparation method for composite modified recessed native alcohol-base foundry coating suspending agent, is characterized in that: comprise the following steps:
With the recessed soil of 300 ~ 400 height of eye quality for raw material, appropriate TM-MA complex reagent and appropriate alcohol are mixed uniformly;
Add 5 ~ 10 grams of recessed soil, this sample is put in supersonic generator, stir and fully vibration;
Filter after placing a period of time, 60 ~ 80 DEG C of oven dry, obtain the composite modified attapulgite suspending agent of TM-MA.
