Abstract
The invention relates to a multifunctional eraser composition. The composition is prepared through using 25-35 parts by weight of a polyvinyl chloride resin slurry, 15-25 parts by weight of dioctyl phthalate, 4-8 parts by weight of calcium carbonate, 0.1-0.4 parts by weight of a stabilizing agent, 15-25 parts by weight of calcium stearate, 10-15 parts by weight of sodium silicate, 0.2-0.8 parts by weight of dichlorobenzene, 0.1-0.4 parts by weight of a nonionic surfactant, 15-25 parts by weight of N-methylformamide and 10-15 parts by weight of a foaming agent. The making method of the composition comprises the following steps: mixing the above components, uniformly stirring, pressurizing at 120DEG C, heating to 165DEG C, dumping the obtained mixture into a mold, and carrying out pressure forming to obtain the composition. The multifunctional eraser composition is convenient to use, and can eliminate a plurality of stains comprising pen and Chinese writing brush writings and pencil and ball pen writings.
Description
technical field [0001] The invention relates to an eraser composition, in particular to a multifunctional eraser composition. Background technique [0002] In the prior art, the erasers that people use when erasing pen writing, ballpoint pen writing and pencil writing are different, and cannot be used in combination, which is very inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-use multifunctional rubber composition aiming at the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved by the following technical solutions. The present invention is a multifunctional rubber composition, which is characterized in that: it is made of the following raw materials in weight ratio, [0005] Polyvinyl chloride resin pulp 25-35; dioctyl phthalate 15-25; [0006] Calcium carbonate 4~8; stabilizer 0.1~0.4; [0007] Calcium stearate 15-2...
