The present invention discloses one kind of environment protecting konjaku paint for both outer and inner walls produced with konjaku powder as plant high-molecular matter and flyash and its production process. The present invention features that konjaku powder and flyash are first bouble modified chemically and mixed physically to obtain aquosol as modified product and that the formulation consists of konjaku powder, styrene-acrylic emulsion, light calcium, talcum, OK powder, titanium white and water. Compared with available technology, the present invention has the advantages of wide material source, no environmental pollution, excellent product performance, low production cost, etc.

Description

A kind of konjaku coating for internal and external wall and production technique
Technical field
The invention belongs to technical field of coatings, be specifically related to utilize natural plant polymer such as konjaku powder and fly powder prepare a kind of coating for internal and external wall, the invention still further relates to the production technique of this coating of preparation.
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, utilize natural plant polymer such as konjaku powder and fly powder to be a kind of environment-friendly type konjaku of raw material production coating for internal and external wall, prepare the production technique of this coating,, improve the performance of coating to reduce the production cost of coating.
The present invention is achieved through the following technical solutions:
A kind of konjaku coating for internal and external wall comprises the natural plant polymer, konjaku powder and/or fry starch of konjak is carried out the two modifications of chemistry and physical blending handle and make work in-process, and proportioning by weight percentage is as follows:
(a) konjaku powder 1.2-3.0, benzene emulsion 5.0-12.0, hydrogen peroxidase 10 .01-0.02, trisodium phosphate 0.12-0.20, polypropylene glycol 0.1-0.3, benzoglyoxaline Urethylane 0.1-0.3, fine particle calcium carbonate 10.0-20.0, talcum powder 3.0-5.0, OK powder 8.0-10.0, titanium dioxide 2.0-10.0, sodium ethylene diamine tetracetate 0.3-0.5, all the other are water.
(b) konjaku powder 0.8-4.0, benzene emulsion 55.0-65.0, titanium dioxide 7.0-25.0, alcohol ester-12 0.7-1.6, polyacrylic ester 0.5-1.5, Sodium hexametaphosphate 99 0.1-0.4,2,2 '-two sulphur two (N-methyl-benzamide) 0.1-0.3, tributyl phosphate 0.1-0.14, ammoniacal liquor 0.3-0.4, all the other are water.
A kind of production technique for preparing the konjaku coating for internal and external wall prepares 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 for internal and external wall: 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, advances people's vibratory screening apparatus then, the mashing pump people material-compound tank that sieves, 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.
Embodiment
Embodiment: the production technique of preparation konjaku coating for internal and external wall:
1) production technique of Rhizoma amorphophalli glucomannan modified water colloidal sol: in reactor, add 200 kg of water, be heated to 65-100 ℃, begin to stir, drop into konjaku powder 2-10 kilogram, add NaOH behind the 10min, transfer pH to 7-11, add catalyst Fe SO 20.002-0.01 kilogram, slowly add properties-correcting agent NaClO 0.025-0.02 kilogram, reaction 30-120min reaches the intrinsic viscosity that needs to viscosity, termination reaction, add HCl, adjust pH 3-5 adds or does not add polyvinyl alcohol 0-5 kilogram, till reaction 30-120min meets the requirements to modified product, be neutralized to pH7, cool off stand-byly, this is a Rhizoma amorphophalli glucomannan modified water colloidal sol;
