Abstract
The invention discloses high-temperature good-strength quartz-based expendable pattern paint modified by mica powder. The high-temperature good-strength quartz-based expendable pattern paint is prepared from the following raw materials in parts by weight: 100-102 parts of quartz powder, 0.9-1.1 parts of modified starch, 0.9-1.1 parts of carboxymethyl cellulose, 2.4-2.6 parts of sodium bentonite, 0.9-1 part of mica powder, 0.8-0.9 part of tetrapod ZnO whiskers, 0.9-1.1 parts of silicasol, 10-13 parts of ethanol, an appropriate amount of water, 0.5-0.6 part of aluminum sol, 1.1-1.3 parts of nonionic boronates and 0.2-0.3 part of tea tree essential oil. The aluminum sol, the nonionic boronates and the tea tree essential oil are used, so that the bentonite is modified, the lipophilicity of the bentonite is improved, and the cohesiveness and the sagging resistance of the paint to plastic foams are improved; therefore, coatings are uniform and compact, molten steel is prevented from penetrating, the fissility is improved, and the aluminum sol and the nonionic boronates can form heat-resistant oxide after being heated, so that the high temperature strength of the coatings is improved.
Description
Technical field
The present invention relates to lost foam paint technical field, particularly relate to a kind of elevated temperature strength good mica powder modification quartz group lost mould coating and preparation method thereof.
Background technology
Lost foam casting is the foundry engieering of a kind of Near net shape, and coating is the key point of lost foam casting, and the quality of coating property is directly connected to the quality of foundry goods.Lost foam paint is typically made up of refractory aggregate, binding agent, suspending agent, carrier, additive.Silica flour is widely used on lost foam casting as refractory aggregate cheap and easy to get, but because sintering character is poor so that it is application receives certain restriction.And the principle that lost foam paint is at the beginning of design should sinter exactly, peel off again.If sintering character can be poor under pouring temperature for refractory aggregate, then can not form the liquid phase of q.s.So coating cannot form densification and have the sinter layer of sufficient intensity, bears incessantly molten metal washing away when cast, corrosion function, and molten metal can pass through coating erosion casting mold, and foundry goods is easily generated the defects such as scab.Even if not causing scab the most easily to produce coating be bonded at the phenomenon being not easily stripped on foundry goods.The major measure improving lost foam paint sintering character has: 1. introduce suitable sintering aid, utilizes the liquid phase that sintering aid is formed, and reaches the purpose accelerating material diffusion with acceleration of sintering；2. formed composite aggregate, fusing point reduction and the temperature starting to sinter by the refractory aggregate that fusing point is different also to decrease.If selecting suitable composite aggregate and proportioning, then coating can be made to produce a certain degree of sintering under pouring temperature.This problem uses mica powder to improve the sintering character of quartz group lost mould coating as sintering aid." mica powder impact on quartz group lost mould coating sintering character " literary composition have developed a kind of lost foam paint with high refractoriness and low fever's node, and this coating has good sintering character and stripping performance.
But mica bad dispersibility in coating, suspension are poor, easily cause the bending strength after sintering uneven, and stripping performance is the most uneven, and mica slabbing, can obstructing air holes, affect gas and discharges, cause bleb phenomenon, need improvement.
Additionally also need to improve the problems such as the hardness of coating, compactness, elevated temperature strength, crack resistance, gas permeability, bending strength, sag resistance, brushing performance, agglutinating property along with the progress of foundry engieering.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of elevated temperature strength good mica powder modification quartz group lost mould coating and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of elevated temperature strength good mica powder modification quartz group lost mould coating, is prepared by the raw materials in: silica flour 100-102, modified starch 0.9-1.1, carboxymethylcellulose calcium 0.9-1.1, sodium bentonite 2.4-2.6, mica powder 0.9-1, four acicular type zinc oxide crystal whisker 0.8-0.9, Ludox 0.9-1.1, ethanol 10-13, water are appropriate, Alumina gel 0.5-0.6, nonionic borate 1.1-1.3, tea tree ethereal oil 0.2-0.3.
The preparation method of described elevated temperature strength good mica powder modification quartz group lost mould coating, comprises the following steps:
(1) Ludox is added in ethanol, stir, add mica powder to stir, be heated to 60-70 DEG C, add four acicular type zinc oxide crystal whisker while stirring, it is heated to 70-75 DEG C, ultrasonic disperse 3-4 minute, continues stirring complete to ethanol volatilization, pulverizes, cross 100-150 mesh sieve, obtain modified micaceous powder；
(2) by nonionic borate, tea tree ethereal oil, sodium bentonite mixing, grind uniformly, add Alumina gel, grind uniformly, obtain modified alta-mud；
(3) modified starch, carboxymethylcellulose calcium are added to the water, stir, add described modified micaceous powder and described modified alta-mud, stir, obtain mixed material；
(4) described mixed material and other leftover materials are mixed into pasty state, to obtain final product.
The invention have the advantage that the application uses Ludox, lithium magnesium silicate, four acicular type zinc oxide crystal whisker to be modified mica powder, define on mica powder surface nano silicon and and four acicular type zinc oxide crystal whisker, the dispersion stabilization making mica powder improves, and whisker can improve the caking property of mica powder and silica flour, improve cracking resistance, there is whisker to support after sintering and define uniform pore, promote that gas is discharged, reduce bleb.By using Alumina gel, nonionic borate, tea tree ethereal oil that bentonite is modified, improve bentonitic lipophile, thus improve coating and the caking property of plastic foam and sag resistance, making coating uniform fine and close, prevent infiltration of molten steel, fissility improves, and Alumina gel, nonionic borate are regretted forming heat-resisting oxide being heated, improve the elevated temperature strength of coating, be difficult to pulverize, obtain the smooth surface of foundry goods.
Detailed description of the invention
A kind of elevated temperature strength good mica powder modification quartz group lost mould coating, is made up of the raw material of following weight portion (kilogram): silica flour 100, modified starch 0.9, carboxymethylcellulose calcium 0.9, sodium bentonite 2.4, mica powder 0.9, four acicular type zinc oxide crystal whisker 0.8, Ludox 0.9, ethanol 10, water are appropriate, Alumina gel 0.5, nonionic borate 1.1, tea tree ethereal oil 0.2.
