Description
Technical field
The present invention relates to a kind of building and ornament materials and preparation method thereof, relate in particular to ripe rubber powder of a kind of environment-friendly type and preparation method thereof.
Background technology
Along with people's standard of living improves constantly, people more and more note residential building finishing quality and class, environmental protection is proposed new requirement.Environmental issue becomes the focus that people pay close attention to.The construction and decoration auxiliary material of some discontented toe ring guaranteed requests must be improved to adapt to the requirement of people to environmental quality.Traditional body of wall finishing generally adopts formulated putty such as 107 glue, dry powder, talcum powder, lime as auxiliary material, though but this auxiliary material can play certain protection against the tide, mildew-proof function, but because tackiness is poor, often cause body of wall to bubble, ftracture, and it is mouldy or the like under the environment of humidity, and because the processing restriction, majority contains objectionable impuritiess such as formaldehyde, benzene, has a strong impact on the healthy of user and occupant.Therefore, a kind of traditional 107 finishing material that add dry powder, talcum powder, lime, the preparation of paper muscle that replace must be arranged.The new decorative material that ripe rubber powder needs as this up time arises.
Existing on the market now ripe rubber powder prescription is complicated, needing to add multiple macromolecule organic reacts as properties-correcting agent, therefore cause deficient in stability on the processed finished products performance, and aspect process for processing, must earlier starch be carried out modification, and then carry out subsequent reactions such as etherificate, need polystep reaction just can make finished product, operation is responsible for, and cost is bigger.
Summary of the invention
The object of the present invention is to provide ripe rubber powder of a kind of building decoration multi-usage and preparation method thereof, with simple formulation and easily preparation section remedy the deficiencies in the prior art, prepare that performance is good, the high finished product of stability.
The weight ratio of constituents of the ripe rubber powder of building decoration multi-usage disclosed by the invention is formed and is comprised:
100 parts of starch;
0.097 part of properties-correcting agent;
Ethanol 25-27 part;
Etherifying agent 20-25 part;
Paste agent 18-24 part;
40 parts in water.
Above starch is one or more in W-Gum, yam starch, the tapioca (flour), and starch granules is 20-120um.
Described properties-correcting agent is epoxy chloropropane, and consumption the best is 0.1 part.
Described etherifying agent is a Monochloro Acetic Acid, and consumption the best is 21 parts.
Described paste agent is a sodium hydroxide.
The method for preparing the ripe rubber powder of above-mentioned building decoration multi-usage is as follows:
A. etherification starch: starch is added in 1500 liters of kneaders, and start stirs, add etherifying agent, properties-correcting agent, alcoholic acid mixed solution, temperature is controlled at 30-35 ℃, and the time was controlled at 20-30 minute, etherification starch;
B. gelatinization crosslinking reaction: slowly splash into paste agent in etherification starch, temperature is controlled at 35-55 ℃, and the dropping time was controlled at 55-60 minute, and insulation is 10-20 minute after the discharging;
C. hydrolysis reaction: above-mentioned resultant is joined in 500 liters of kneaders, add resultant weight the hydrolysis of 60-100% water, stir hydrolyzation material;
D. hydrolyzation material drying: hydrolyzation material is thrown into gelatinization on the multiple roll drum drier, drying, temperature be controlled at 170 ℃, vapor pressure is controlled to be 5-6Mpa, makes sheet, divides grade packaged finished product.
The ripe rubber powder of building decoration multi-usage of the present invention is to utilize etherifying agent and starch generation bimolecular nucleophilic substitution.Because they can destroy in the starch granule hydrogen bond between the molecule or form the solubility mixture with starch, thereby also can make starch generation gelatinization and crosslinked.Prepare the ripe rubber powder of high performance multi-usage.This powder can replace the finishing material of not environmental protection such as 107 glue, 801 glue, 901 glue.Can be used as various in the plaster of exterior walls and coating and bonding wallpaper, leveling mortar, waterproof, papermaking, weaving, oil and with fields such as chemical industry and makeup.Show cohesive strength height, workability excellence, mildew-resistant, performance such as antibiotic.
The present invention compares with present production technology has following advantage:
1. the present invention has changed present production technique, etherifying agent, linking agent and has directly joined in the starch, and etherificate and crosslinkedly carry out has simultaneously reduced the reaction times, has accelerated reactions steps, has improved reaction efficiency;
2. the present invention directly adopts paste agent to join in the etherificate cross-linking starch, makes that etherificate is crosslinked, gelatinization accomplishs without any letup, and improved product viscosity, increased clinging power;
3. the present invention does not have that the three wastes are discharged, technology is simple, easy to operate.
After testing, every technical indicator of gained finished product of the present invention is as follows
| 8 | Free formaldehyde | g/kg | ≤0.8 | 0.1 |
| 9 | Benzene | g/kg | 0.2 | 0 |
| 10 | Toluene adds ten dimethylbenzene | g/kg | G | 0 |
| 11 | The mildew-resistant grade | - | - | 0 |
Show that from top numeral product of the present invention does not contain harmful materials such as benzene, toluene, ten dimethylbenzene.The content of free formaldehyde is well below standard content.This powder environmental-protecting performance is good, viscosity is high, and therefore product of the present invention has vast market advantage and prospect.
