Abstract
The invention discloses plant modified polymer powder, which is characterized in that: konjac and potatoes are taken as main materials; and a preparation method comprises the following steps of: cleaning the konjac and the potatoes respectively to remove impurities, peeling, weighing the konjac and the potatoes according to a mass ratio of 1:(2-3), crushing, mixing, adding a crosslinking agent, soda ash and water, reacting at the temperature of between 100 and 130DEG C under 1 to 2 atmospheric pressure for 20 to 40 minutes, performing spray drying or drying on the obtained product, crushing into 100 meshes, adding hydroxyethylcellulose, and uniformly mixing to obtain the product. The obtained plant modified polymer powder is a novel putty powder adhesive, is prepared from natural plants serving as the raw materials, is nontoxic, free from formaldehyde pollution, harmless to a human body, low in cost and simple in process, and has the advantages of wide addition amount regulating range, small addition amount, better adhesion effect, no influence on construction property and simple compounding, so the plant modified polymer powder can directly replace cassava starch or corn starch to serve as the putty powder adhesive.
Description
Technical field
The present invention relates to a kind of putty powder sticker, specifically a kind of plant modified poly rubber powder.
Background technology
Putty is that metope is repaired smooth its finishing material that reaches smooth fine and smooth effect that makes, and mainly is made up of filler (lime carbonate), sticker (glue or rubber powder), solvent (water or other solvents) and additive (auxiliary agent).At present the putty material that uses of finishing mainly contains on-the-spot mixed matching (like Z 150PH urea-formaldehyde glue liquid+Paris white+ripe rubber powder etc.), finished product water and type (putty powder+water) etc.
Wherein on-the-spot mixed matching need be earlier with Z 150PH+water and add SEPIGEL 305, formaldehyde, urea etc. and be brewed into glue (having producer to manufacture the glue production marketing specially) through high temperature; Become the construction of paste putty with material field mix such as glue and lime carbonate again; This putty defective is that cost is high; Complex procedures, formaldehyde pollution etc.
Finished product water and type putty powder mainly adopt rubber powders such as tapioca(flour) or W-Gum as sticker, carry out factory's pre-mixing can with Paris white and become production marketing, and the on-the-spot water that only need add is constructed.Rubber powder is the core starting material of putty powder, and to intensity, application property and the weather resistance decisive role of putty powder, the quality of rubber powder has determined the quality of putty powder.Though and the defective of tapioca(flour) commonly used is that cohesive action is arranged, if addition, is difficult for batch scraping greatly then influence the workability of putty powder, the cohesive strength if addition is little (sticking power) is low not to reach requirement, is unfavorable for composite; W-Gum is then little to the cohesive strength effect, and is short with the putty powder or the work-ing life of these two kinds of made, is prone to the hollowing shedding, or the workability difference etc.
Summary of the invention
The objective of the invention is to the defective to tapioca(flour) or W-Gum, provide a kind of addition setting range big, less addition promptly reaches the plant modified poly rubber powder that bond effect does not preferably influence simultaneously workability.
Said plant modified poly rubber powder is a major ingredient with konjaku and yam, earlier respectively with after its cleaning and removing impurities, the peeling; Take by weighing konjaku and yam according to mass ratio 1: 2～3, and it is pulverized mixing, add linking agent, soda ash and water; 1～2 normal atmosphere, 100～130 ℃ of following reactions 20～40 minutes; With gains spray-dried or the oven dry be crushed to 100 orders, add Natvosol again, mix and promptly get product.
The addition of linking agent, soda ash, water, Natvosol is in per 100 kilograms of described major ingredients, adds 0.1～0.3 kilogram linking agent, 0.1～0.3 kilogram soda ash, 180～220 kilograms water and 3～5 kilograms Natvosol.Said linking agent is Monochloro Acetic Acid or trichoroacetic acid(TCA).
The starch content of konjaku and yam is higher, and the rubber powder of gained contains more water miscible group after process modification, the polymerization, makes it strengthen stability, reduced gelatinization point, improve viscosity.The plant modified poly rubber powder that makes can be used as thickening material, sticker, emulsifying agent etc.
Be used in the putty powder of building materials field, can increase the workability of putty powder, be easy to criticize and scrape; Less addition can reach bond effect preferably, be easy to putty powder in other additive compound, the putty powder good stability after batch scraping; Be difficult for the hollowing shedding, long service life.
Therefore, the plant modified poly rubber powder that the present invention makes has the following advantages: plant modified poly rubber powder is a kind of putty powder sticker, is raw material with the natural phant, nontoxic, formaldehydeless pollution, harmless; It is big to have the addition setting range, and less addition promptly reaches bond effect preferably, does not influence workability simultaneously, is easy to composite advantage, therefore can directly substitute tapioca(flour) or W-Gum and use as the putty powder sticker.
