Embodiment 1

[0063] Get jatropha oil 900g, 85.5 gram formic acid (80%), 18g phosphoric acid and add in the glass kettle of 2L, stir, drip the 27.5% hydrogen peroxide of 558 grams, react 6~10 hours under the condition of 30~70 ℃, The upper layer was separated after standing; the epoxy jatropha oil was obtained after refining, and its epoxy value was detected to be 3.95%, and the moisture: 0.1%.

Embodiment 2

[0065] Take jatropha oil 900g, 100 grams of acetic acid and add in a 2L glass kettle, stir, add 600 grams of 27.5% hydrogen peroxide dropwise, react at 30-70°C for 6-10 hours, and separate the upper layer after standing; Epoxy jatropha oil was obtained after refining, its epoxy value was detected to be 3.85%, moisture: 0.11%.

Embodiment 3

[0067] Add 800 g of epoxy jatropha oil, 450 diisopropanolamine, and 0.2 g of sodium methoxide, the product in Example 1, into a 2L glass kettle, stir and raise the temperature, control the reaction temperature to 70-200°C, and the reaction time is 12 hours. The obtained bio-based polyol product A was 1230 g, the hydroxyl value was 471 mgKOH / g, and the water content was 0.1%.

Abstract

The invention relates to a polyurethane foam plastic prepared by little tung oil. The biologic group polylol is prepared by epoxidation, ring cleavage, alcoholysis and addition of the tung oil, then the biologic group polylol and polyether glycol are used as basic raw materials to prepare compound materials with assistant agent; finally the compound materials are mixed evenly with blowing catalyst, then react with polyisocyanate with the yield of effervescence, thus obtaining the polyurethane foam plastic. The invention has the advantages that: 1. the little tung oil of the raw material of the biologic group polylol is renewable resource and the little tung is abundant with low cost and is unnecessary to get resources from people; 2. the preparation technique of the biologic group polylol has simple operation, good adjustability of product functionality, comparatively good property and high rate of petrified polyether glycol substation reducing dependence to petrified products; 3. the biologic degradability of polyurethane foam plastic prepared by the little tung oil and biologic group polylol is comparatively good and friendly to environment.

Description

technical field [0001] The invention relates to a polyurethane foam prepared by using jatropha oil, which belongs to the field of organic synthetic materials. Background technique [0002] With the expansion of polyurethane foam applications and the rapid development of the world economy, the global demand for polyurethane foam is growing rapidly. The main raw materials of polyurethane foam are isocyanate, polyol, blowing agent, foam stabilizer, catalyst and flame retardant. Polyols mainly use petroleum polyether polyols as raw materials, and petroleum resources are non-renewable resources. With the development of industry, petroleum resources are becoming increasingly tense, and the price of petroleum polyether polyols is also increasing. At the same time, in recent years, people's awareness of environmental protection has been continuously enhanced, and the polyurethane foam prepared from renewable natural resources has become a research and development hotspot in various...
