Embodiment 1

[0024] The present embodiment powdery adhesive comprises the composition of following parts by weight:

[0025] 50 parts of epoxy resin; 10 parts of powdery phenolic resin, 90 parts of plant raw materials; 30 parts of light-colored liquid resin; 2 parts of paraffin, 9 parts of filler, 0.1 part of boric acid; , the ratio of yellow zeolite to orange peel is 2:1; the filler is hematilite powder and carboxymethyl starch, and the ratio of hematilite powder and carboxymethyl starch is 2:1;

[0026] The preparation of described light-colored liquid resin is:

[0027] Refined rosin and fumaric acid accounting for 1.5% of the total mass of the refined rosin are reacted through diene synthesis to obtain fumaric acid modified refined rosin. The reaction temperature is 200°C and the reaction time is 1 hour. Increase the molecular weight of rosin and increase simultaneously Softening point and acid value; add the diethylene glycol that accounts for 11% of described refined rosin gross mas...

Embodiment 2

[0035] The present embodiment powdery adhesive comprises the composition of following parts by weight:

[0036] 80 parts of epoxy resin; 20 parts of powdery phenolic resin, 100 parts of plant raw material; 40 parts of light-colored liquid resin; 8 parts of paraffin, 10 parts of filler, 0.5 part of boric acid; The ratio of chrysanthemum and orange peel is 2:1; the filler is hematilite powder and carboxymethyl starch, and the ratio of hematilite powder and carboxymethyl starch is 2:1;

[0037] The preparation of described light-colored liquid resin is:

[0038] Refined rosin and fumaric acid accounting for 1.5% of the total mass of the refined rosin are reacted through diene synthesis to obtain fumaric acid modified refined rosin. The reaction temperature is 210°C and the reaction time is 2 hours. Increase the molecular weight of rosin and simultaneously increase the Softening point and acid value; add the diethylene glycol that accounts for 12% of described refined rosin gross...

Abstract

The invention discloses a powdery adhesive, and relates to the technical field of chemical engineering. The powdery adhesive is prepared from the following compositions in parts by weight: 50 to 80 parts of epoxy resin, 10 to 20 parts of powdery phenolic resin, 90 to 100 parts of plant raw material, 30 to 40 parts of light liquid resin, 2 to 8 parts of paraffin, 9 to 10 parts of filling agent, and0.1 to 0.5 part of boric acid, wherein the plant raw materials comprise artemisia annua powder and tangerine peel powder; the filling agent comprises epidesmine powder and carboxymethyl starch. Compared with the prior art, the powdery adhesive has the advantages that because the filling agent comprises the epidesmine powder and the carboxymethyl starch, the epidesmine powder is framework silicateconsisting of silica tetrahedron and alumina tetrahedron; a plurality of open voids and passages are formed in the mineral, the strong water-absorbing ability is realized, the water is locked, and the influence to damping of burning incense is avoided; the defects of deformation of burning incense, difficulties in ignition, and incomplete burning due to easiness in moisture absorbing in the traditional burning incense because of use of wood charcoal powder are overcome.

Description

technical field [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a powdery adhesive. Background technique [0002] Fragrance is not only fragrant and nourishing for the nose, but also nourishes the body and mind, eliminates filth and cures diseases, and nourishes the mind and health. Human beings' preference for incense is an innate nature. Fragrance, mobilizes the spirituality of the mind in the joy, regulates the breath, clears the nose, opens the mind, and harmonizes the body and mind between the visible and the invisible. "Burn the sadness of my life, in exchange for a sliver of your understanding." A good fragrance is not only fragrant and makes people happy, but also can help people reach a state of tranquility and agility, and achieve calmness in a state of mind and spirit. In terms of disease prevention and health preservation, as early as the Han Dynasty, the famous doctor Hua Tuo once made sachets with c...
