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 [0001] The invention relates to a novel putty powder binder, in particular to a plant-modified polymerized rubber powder. Background technique [0002] Putty is a decoration material for repairing and leveling the wall to achieve a smooth and delicate effect. It is mainly composed of filler (calcium carbonate), binder (glue or powder), solvent (water or other solvents) and additives (auxiliary). At present, the putty materials used for decoration mainly include on-site mixed type (such as polyvinyl alcohol urea-formaldehyde glue + calcium carbonate powder + cooked rubber powder, etc.), finished water and type (putty powder + water), etc. [0003] Among them, the on-site mixing type needs to add polyvinyl alcohol + water and add polyacrylamide, formaldehyde, urea, etc. to boil at high temperature to make glue (some manufacturers specially make glue products for sale), and then use glue and calcium carbonate, etc. The materials are mixed into paste putty const...
