Description
Technical field
The invention belongs to building material technical fields, and in particular to the anti-glutinous rice glue and preparation method thereof that warps of one kind.
Background technique
Instantly, requirement of the people for finishing material is higher and higher, and the environmental-protecting performance of finishing material considers as many people
One of necessary condition.Wallpaper as a kind of house decorative material, because its with color multiplicity, safety and environmental protection, it is easy for construction,
The features such as can be adapted for different occasions is accepted extensively by masses.Everybody approval that the wallpaper material of safety and environmental protection is subject to, but
It is relative to wallpaper, the safety of auxiliary material is also the problem of can not be ignored.
Currently, on the market, the glue pasted for wallpaper substantially has rubber powder, rubber cement, wet glue etc., and the raw material of general rubber cement is
Formaldehyde is the harmful chemical reagent of a kind of pair of human body, and rubber powder can cooperate rubber cement to use, or is used alone, but it is environmentally friendly
Performance is relatively poor.Currently, the glutinous rice glue in wet glue is the first choice of house decoration, it is a kind of high-performance glue that wallpaper is pasted.
Glutinous rice glue is also referred to as glutinous rice glue, be with pure natural glutinous rice or glutinous rice is raw material, by glutinous rice purification, grinding, dry etc.
12 procedures and the environment-protective adhesive formed, applied widely, viscosity is long.When pasting wallpaper, Glutinous rice wet glue is due to its ring
The characteristics of guarantor, cohesion are by force, cost is relatively low, obtain more and more extensive use.Glutinous rice glue is mainly the agent based on each kind of starch,
It is aided with various auxiliary materials, a kind of environment-friendly water-soluble as made from temperature reaction in a kettle after suitable proportion is highly viscous
Amylan, then cooling discharge carries out being packaged to be finished product glutinous rice glue.During producing glutinous rice glue, it is often necessary to add one
A little auxiliary materials or auxiliary agent, with indexs such as the viscosity or the stability that improve product, and the general environmental protection grade of these auxiliary agents is inadequate.
The wet glue of Japan, is a kind of dedicated high-performance solid of wallpaper, it is to rise in Japan and be passed to other ground earliest
Area, thus it is also known as " Japanese glue " in the line.Wet glue can be divided into glutinous rice glue and plant starch glue two with the differentiation of its raw materials for production
Kind.Glutinous rice glue has merged Japanese tip chemical institute technology, and resulting by domestic high-tech research institute's Promotion Transformation formula
Achievement is using natural edible glutinous rice as main material, it comes unglued simultaneously or a kind of pure natural glutinous rice adhesive easy to use
When need to only be added into water and uniformly stirred use, without in addition addition viscosify rubber cement.Pasting thick and heavy wallpaper Shi Gengxian superior function.
Amylan has merged achievement obtained by Japanese tip chemical institute technology, with modified starch (by chemical modification
Starch, not pure natural glutinous rice glue is good naturally for environmentally friendly degree) it is primary raw material, current market sales of " glutinous rice glue " product
Mainly this kind of product since its raw materials for production does not have the ingredient of glutinous rice, and is known as " pseudo- glutinous rice glue " in industry, this kind of " pseudo-
Glutinous rice glue " is most of to be presented translucent colloidals, due to being added to a large amount of " thickeners " in production process, and when leading to construction not
It easily adjusts and converts, generally to divide 2-3 times and be watered.
Glutinous rice mortar is perhaps that the first uses composite mortar made of organic and inorganic raw material in the world.Glutinous rice mortar ratio
Carbonate-free lime mortar strength is bigger, more water resistance, and Zhang Bingjian is additionally considered that it is one of greatest technological innovation in history.Building
Worker goes to build coffin pit, pagoda, city wall using glutinous rice mortar, and some of them building exists so far.Some heritage buildings are very hard
Gu or even modern bull-dozer is all difficult to push over, moreover it is possible to the very big earthquake of bearing strength.
The adhesion strength of glutinous rice glue is poor at present, as hardening phenomenon easily occurs in the extension of time after construction, wallpaper is caused to rise
It sticks up, influences indoor beauty, it would be highly desirable to solve.
