Abstract
The present invention discloses a kind of konjak cloud paint and its preparation method. Firstly, it makes the konjak fine flour or konjak glucomannan in the flying powder undergo the processes of chemical double modification and physical blending treatment to obtain the modified product hydrosol, and in the described formula the konjak fine flour, pearly pigment, titanium white powder, methyl benzimidazolecarbamate, sodium pyrophosphate, diethylene glycol monoethyl ether, 10% AlCl3 aqueous solution and water are contained. As compared with existent technology said invention has the advantages of extensive raw material source, having no environmental pollution, good product performance and low production cost.
Description
Technical field
The invention belongs to coating and technical field of producing thereof, be specifically related to utilize konjaku powder and fly powder and produce the konjaku cloud paint, also relate to the production technique for preparing this coating.
Background technology
Before the present invention made, the production of building coating mainly utilized the synthetic macromolecule raw material to produce, and cause environmental pollution easily, and production cost is higher.Utilized crude substance mainly to concentrate on starch and animal plasma aspect in recent years as the report of filmogen development building coating, similarly invention is as CN95100825 CN96118252, CN97108172, in order to replace polyvinyl alcohol comparatively expensive in 106 coating, though this method can reduce the production cost of coating, but the poor performance of coating, and formaldehyde is seriously polluted.
Summary of the invention
The invention reside in the deficiency that overcomes prior art, is raw material production environment-friendly type konjaku cloud paint and preparation technology thereof with konjaku powder with flying powder, to reduce production costs, improves the performance of coating.
The present invention is achieved through the following technical solutions:
A kind of konjaku cloud paint comprises the natural plant polymer, is raw material with konjaku powder and/or fry starch of konjak, and this raw material is handled the work in-process of making coating through two modifications of chemistry and physical blending, and proportioning by weight percentage is:
Konjaku powder 2.0-5.0, pearly pigment 4.0-15.0, titanium dioxide 3.0-10.0, benzoglyoxaline Urethylane 0.01-0.03, trisodium phosphate 0.01-0.03, diethylene glycol monoethyl ether 1.0-3.0,10%AlCl
3Aqueous solution 0.3-0.8, all the other are water.
A kind of preparation technology of konjaku cloud paint, according to the following step:
1) production technique of Rhizoma amorphophalli glucomannan modified water colloidal sol: by weight percentage, the water that in reactor, adds 85-90%, be heated to 65-100 ℃, begin to stir, drop into the konjaku powder of 0.9-4.5%, add NaOH behind the 10min, transfer pH to 7-11, add the catalyst Fe SO of 0.0009-0.0045%
2The properties-correcting agent NaClO that slowly adds 0.001-0.009%, reaction 30-120min reaches the intrinsic viscosity that needs to viscosity, termination reaction, add HCl, adjust pH 3-5, the polyvinyl alcohol of adding 0-2.2%, till reaction 30-120min meets the requirements to modified product, be neutralized to pH7, cool off stand-byly, be Rhizoma amorphophalli glucomannan modified water colloidal sol;
2) production technique of konjaku coating: in mixer, drop into set by step 1) the modified konjaku water-sol of producing by prescription, add dispersion agent then, under the 800-2000r/min homogenizer, stir, slowly add the water in color stuffing and the prescription, disperse 10-50min, the sanitas and the defoamer that add 0.1-0.5%, entering sand mill disperses, rate of dispersion is controlled at 10-30Kg/min for the first time, rate of dispersion is controlled at 5-20Kg/min for the second time, and fineness of dispersion can pass through 150 mesh sieves, enters vibratory screening apparatus then, the slurry that sieves pumps into material-compound tank, the canned finished product that gets.
The present invention has following positive effect:
The konjaku building coating is to be the building coating of main film forming substance with natural polymer konjaku Konjac Glucomannan, the production process non-environmental-pollution, and product non-volatility solvent is a kind of green environmental friendly coatings.It also has resource-saving, the characteristics of less energy-consumption simultaneously.Coating property reaches the national standard of synthetic resin emulsion interior wall, synthetic resin emulsion exterior wall respectively, but its price only is their 1/3rd to 1/10th, has preferable performance price ratio.
The present invention can the mass consumption konjaku powder and is flown powder, and the development and use of China's mountain area special product crop konjaku resource are had great importance.For coatings industry provides a kind of novel filmogen, meet the coatings industry environment-friendly type with the present invention fully, the developing direction of less energy-consumption and resource-saving.
