Embodiment 1
[0037] A method for using lignin in phenolic resin molding compound, specifically according to the following steps:
[0038] S1: Preparing the proportioning base liquid, using phenolic resin as the medium, heating the base liquid to a liquid state, and stirring continuously to make the overall temperature of the base liquid uniform, as a binder, pour the prepared base liquid into a corrosion-resistant in the proportioning container;
[0039] S2: Preparation of mixed raw materials. The mixed raw materials include: lignin powder, discarded rubber and plastic bags, sanfei powder granules, talcum powder, urotropine solution, stearic acid powder, among which the discarded rubber and plastic bags are heated To liquid state, heat the lignin powder and stearic acid powder to liquefaction, grind the Sanfei powder particles into powder form, the mass-number ratio between each raw material and binder is: lignin powder 131: binder 95: Waste rubber and plastic bags 96: urotropine 20: talc...
Embodiment 2
[0049] A method for using lignin in phenolic resin molding compound, specifically according to the following steps:
[0050] S1: Prepare the base liquid by using epoxy resin as the medium, heat the base liquid to a liquid state, and keep stirring to make the overall temperature of the base liquid uniform. As an adhesive, pour the prepared base liquid into a durable Corroded proportioning container;
[0051] S2: Preparation of mixed raw materials. The mixed raw materials include: lignin powder, discarded rubber and plastic bags, sanfei powder granules, talcum powder, urotropine solution, stearic acid powder, among which the discarded rubber and plastic bags are heated To a liquid state, heat the lignin powder and stearic acid powder to liquefaction, grind the Sanfei powder particles to a powder state, and the mass-number ratio between each raw material and the binder is: lignin powder 131: binder 92: Discarded rubber and plastic bags 89: urotropine 21: talcum powder 8: Sanfei ...
Embodiment 3
[0061] A method for using lignin in phenolic resin molding compound, specifically according to the following steps:
[0062] S1: Preparing the proportioning base liquid, using acrylic resin adhesive as the medium, heating the base liquid to a liquid state, and stirring continuously to make the overall temperature of the base liquid even, as an adhesive, pour the prepared base liquid into In a corrosion-resistant proportioning container;
[0063] S2: Preparation of mixed raw materials. The mixed raw materials include: lignin powder, discarded rubber and plastic bags, sanfei powder granules, talcum powder, urotropine solution, stearic acid powder, among which the discarded rubber and plastic bags are heated To a liquid state, heat the lignin powder and stearic acid powder to liquefaction, grind the Sanfei powder particles to a powder state, and the mass-number ratio between each raw material and the binder is: lignin powder 122: binder 88: Discarded rubber and plastic bags 85: ...
