Abstract
The invention discloses a method for producing a thermal insulation material by using waste paper. The method comprises the steps of crushing, ink removing, removing, bleaching, addition, forming, and dehydration drying. According to the crushing step, waste paper is crushed; according to the ink removing step, the crushed paper is subjected to an ink removing treatment by using an ink removing agent; according to the removing step, printing ink particles in the paper pulp are removed, and large particle deposition is prevented; according to the bleaching step, paper pulp is bleached; according to the addition step, an inorganic porous material perlite is added into the paper pulp; according to the forming step, paper pulp is injected into a mold with a planar shape, a cylindrical shape, or the like without the application of an adhesive, such that a corresponding shape is formed; and according to the dehydration drying step, the mold with the paper pulp is dehydrated and dried, such that a biological thermal insulation material with a needed shape is formed.

A kind of method of utilizing waste paper to produce heat-barrier material is characterized in that, said method comprising the steps of;
Steps A: pulverizing process carries out size degradation with waste paper.
Step B: the deinking operation is to utilize deinking agent that shredded paper is carried out deinking to process, and makes ink particle and paper fiber separation.
Step C: removing step is that the ink particle in the paper pulp is removed, and prevents that the bulky grain particle is in deposition.
Step D: bleaching process is that paper pulp is bleached, and the whiteness of paper pulp is improved.
Step e: adding operation is to add inorganic vesicular material in paper pulp.
Step F: molding procedure is injected paper pulp in the situation of not using adhesive in the mould of tabular, cylinder or other shape and is made corresponding shape.
Step G: the dewatered drying operation is that the mould that will inject paper pulp dewaters, drying is made the biological heat-barrier material of required form.
Described deinking operation is used a kind of surfactant and composite deinking agent that forms of organic solvent of containing, can be effectively with ink particle and paper fiber separation.
In the described removing step, add ink absorbent, ink particle and the sicker activity by self is attached together it, reduce its viscosity.
Described bleaching process adds chlorine dioxide and bleaches, and its advantage is that bleaching efficiency is high, and whiteness height and good stability reduce the water dustiness, reduce the paper grade (stock) water yield.
In the described interpolation operation, adding inorganic vesicular material is perlite.
Beneficial effect of the present invention: the operating process that the present invention adopts is simple, by waste paper recycling technology, is that waste paper reclaims, degrades, generates heat-barrier material, reaches the purpose of energy-conserving and environment-protective.
