example 1
[0017] First, weigh 200g of konjac starch and add it to a beaker, and then add 5g of manganese isooctanoate, 2g of calcium isooctanoate and 100mL of deionized water in turn, stir and mix for 5 minutes, then add 10g of n-butyl titanate, stir and mix for 2 minutes, and pour into the beaker Add 10mL of the mixed solution dropwise to the mixture, and control the dropping rate to 1mL / min. After the dropwise addition is completed, stir and react for 1h to obtain a mixture sol, wherein the mixed solution is glacial acetic acid and a mass fraction of 75% ethanol solution in a volume ratio of 1: 10; then the above mixture sol was left to stand at 25°C for 1 hour to gel, and then placed in an oven, dried at 80°C for 2 hours, and after it was naturally cooled to room temperature, it was placed in a ball mill for 30 minutes. , and pass through a 100-mesh sieve to collect the sieved matter, i.e. the drier, for subsequent use; then weigh 30g of glycidyl acrylate type unsaturated polyester re...

[0020] First, weigh 250g of konjac starch and add it to a beaker, and then add 7g of manganese isooctanoate, 2g of calcium isooctanoate and 150mL of deionized water in turn, stir and mix for 7 minutes, then add 15g of n-butyl titanate, stir and mix for 3 minutes, and pour into the beaker 13mL of the mixed solution was added dropwise to the mixture, and the rate of addition was controlled to be 2mL / min. After the addition was completed, the reaction was stirred for 1 hour to obtain a mixture sol, wherein the mixed solution was glacial acetic acid and a mass fraction of 75% ethanol solution in a volume ratio of 1: 10 mixed; then the above mixture sol was left to stand at 28°C for 1.5h to gel, then placed in an oven, dried at 85°C for 2h, and after it was naturally cooled to room temperature, placed in a ball mill for ball milling 35min, and pass through a 110 mesh sieve, collect the sieved material, i.e. the drier, and set aside; then weigh 35g glycidyl acrylate type unsaturated ...
example 3
[0023] First weigh 300g of konjac starch and add it to a beaker, then add 8g of manganese isooctanoate, 3g of calcium isooctanoate and 200mL of deionized water in turn, stir and mix for 8 minutes, then add 20g of n-butyl titanate, stir and mix for 4 minutes, pour into the beaker Add 15mL of the mixed solution dropwise to the mixture, and control the dropping rate to 3mL / min. After the dropwise addition is completed, stir and react for 2h to obtain a mixture sol, wherein the mixed solution is glacial acetic acid and a mass fraction of 75% ethanol solution in a volume ratio of 1: 10 mixed; then the above mixture sol was left to stand at 30°C for 2 hours to gel, then placed in an oven, dried at 90°C for 3 hours, and after it was naturally cooled to room temperature, it was placed in a ball mill and ball milled for 40 minutes , and pass through a 120-mesh sieve to collect the sieved matter, i.e. drier, for subsequent use; then weigh 40g glycidyl acrylate type unsaturated polyester ...
