AI Technical Summary

Problems solved by technology

The current market price of soybean oil is only about half of that of tung oil, and the technology of using soybean oil to make paint has been disclosed, but the performance of the paint is not comparable to that of paint made of tung oil
Due to the low degree of unsaturation of soybean oil, it cannot be directly polymerized with other hard resins (such as 2210 phenolic resin) to refine the phenolic varnish base

Embodiment Construction

[0010] The method of making phenolic waterline paint base with modified soybean oil, first add 100 parts of modified soybean oil and 60 parts of 2210 phenolic resin into the reaction pot and heat it up to 260~270°C to keep it warm and simmer until the viscosity reaches 4 cups. After the measured value is 200-300 seconds, the material is discharged and mixed with 100 parts of petroleum solvent. Wherein the modification method is carried out to soybean oil, wherein the amount of the added substance is measured in parts by mass:

[0011] 1. Mix 100 parts of soybean oil into the reaction pot, heat up to 120±5°C, add 4 parts of fumaric acid under stirring, then heat up to 150±5°C, add 0.12 parts of aluminum trichloride under stirring, and then When the temperature is raised to 180±5°C, heat-preserve for one hour, then when the temperature rises to 220±5°C, heat-preserve for one hour, then add 3 parts of pentaerythritol under stirring, and when the temperature rises to 240±5°C, heat...

Abstract

The invention provides a method for manufacturing a phenolic aldehyde topping paint binder by using vegetable oil. The vegetable oil is modified soybean oil, and the modified soybean oil is obtained by the following steps of: placing 100 parts by mass of soybean oil into a reaction pot and raising the temperature to 120+ / -5 DEG C; then, adding 4-5 parts by mass of fumaric acid under agitating; raising the temperature to 150+ / -5 DEG C, and adding 0.12 parts by mass of aluminum trichloride under agitating and raising the temperature to 180+ / -5 DEG C; keeping the heat and cooking for 50-70 min; then, raising the temperature to 220+ / -5 DEG C and keeping the heat for 50-70 min; then, adding 3-4 parts by mass of pentaerythritol under agitating; and then, raising the temperature to 240+ / -5 DEG C and keeping the heat for 50-70 min. Compared with the prior art, the invention provides a new way for manufacturing the binder by using the vegetable oil; and meanwhile, the method disclosed by the invention adopts the soybean oil with the relatively lower price as the raw material, so that the price of the obtained product is lower, a supply amount can be improved and the financial burden of a user is reduced.

Description

technical field [0001] The invention relates to a method for producing a phenolic water-line paint base with vegetable oil. Background technique [0002] The production of phenolic waterline paint base for ships is traditionally made of tung oil as the main raw material. Tung oil is obtained from tung oil by hot pressing. It is a drying oil with an iodine value greater than 163 and a diene value of 67-71. Heated at high temperature (200~250°C), it can be gelled by self-polymerization, or even completely cured. This special property is due to the polymerization of its main component α-Eleostearin, a property not found in other drying oils. Because of the high iodine value, that is, the high degree of unsaturation and fast polymerization, it can be mixed with 2210 phenolic resin and heated to a certain temperature for heat preservation, adding a certain amount of catalytic additives, and maintaining the temperature for a certain period of time to obtain a paint base with a ce...
