The natural plant oil based plant-carried foam cotton is prepared from a combined material and isocyanate, wherein the combined material comprises the following components in parts by weight: 100 parts of compound polyhydric alcohol, 0-8 parts of a cross-linking agent or a chain extender, 0-3 parts of a compound catalyst, 0.5-4 parts of a foam stabilizer, 0.2-10 parts of foaming agent and 0-50 parts of a filler; the ester number of isocyanate is 0.3-0.75. According to the preparation method, a polyurethane technique is applied to the field of planting; the natural plant oil based plant-carried foam cotton having specific water-absorption and water-retention properties and degradable characteristic can be applied to water retention and desertification prevention of deserts.
Description
Technical field
The present invention relates to the technical field of urethane application material, particularly natural plant oil based the planting of one carries foam and preparation method thereof.
Background technology
Plant cultivation foam and refer to that there is wetting ability, strong soaking effect, the foam of fine water retention capacity, plant seed (as mung bean) can be planted and make germinating growth in foam inside.
The preparation process of conventional urethane foam if desired can water-absorbing-retaining, be generally add there is strong water-retaining capacity additive as polyacrolein etc.Although this method has certain effect to the water-retaining capacity improving polyurethane foam, there is a few point defect:
1, strong absorbent material add the procedure adding urethane processing, add extra cost;
2, strong absorbent material is difficult to the distribution of uniformity in polyurethane foam, causes the absorptive difference of different sites;
3, after repeatedly using, strong absorptive additive easily spins off from foam, causes water-retaining capacity significantly to decline.
Another kind method is in polyol component, use hyperbaric hydrophilic polyether, reacts, obtain desirable soaking effect by the wetting ability of hydrophilic polyether and hydroxyl itself under low isocyanic ester ester number (0.35 ~ 0.7).As US5424338 etc.But the hyperactivity of polyethers used, often cause the abscess of foam, technological process wayward, foam performance is undesirable.
Conventional urethane material all adopts petrochemicals simultaneously, and belong to Nonrenewable resources, along with the consumption of oil, oil price rises violently, and will affect the development of polyurethane industrial.
Therefore, the necessary improvement by the material of urethane own obtains the polyurethane foam of strong water suction.
Summary of the invention
The object of the present invention is to provide a kind of natural plant oil based planting to carry foam and preparation method, applications of polyurethanes technology to planting cultivation field, to have unique absorbing and holding water property and degradable feature, can be applied to desert water conservation, anti-desertification etc. by it.
In order to reach above-mentioned purpose, solution of the present invention is:
Natural plant oil based planting carries foam, is made up of premixed systems and isocyanic ester;
Premixed systems, comprises by weight:

Composite catalyst 0 ~ 3
Suds-stabilizing agent 0.5 ~ 4
Whipping agent 0.2 ~ 10
Filler 0 ~ 50
Isocyanic ester ester number is 0.3 ~ 0.75) ratio.
Described isocyanic ester comprises aromatic isocyanate and aliphatic isocyanates.
Pluronic polyols comprises polyether glycol, liquid polyester polyol and vegetable oil polyol.
Described Pluronic polyols comprises following three kinds of combinations:
Polyvalent alcohol, based on vegetables oil, functionality is 2 ~ 4, hydroxyl value 28 ~ 570mg KOH/g, and consumption is the weight ratio 5% ~ 35% of relative Pluronic polyols total amount;
The polyol of high reactivity propylene oxide, oxyethane, functionality is 2 ~ 3, hydroxyl value 28 ~ 400 mg KOH/g, and consumption is the weight ratio 55% ~ 70% of relative Pluronic polyols total amount;
The polyol of propylene oxide, oxyethane, functionality is 4 ~ 7, hydroxyl value 600 ~ 800 mg KOH/g, and consumption is the weight ratio 10% ~ 40% of relative Pluronic polyols total amount.
Described linking agent is small molecule polyol or the aminated compounds (as glycerine) that functionality is greater than 2.
Described chainextender is small molecule polyol or the aminated compounds (as ethylene glycol) of two functionality.
Described linking agent and chainextender used alone or together.
Described composite catalyst is the two or more combination in two (2-methylamino ethyl) ether, five methyl diethylentriamine, N, N ˊ-dimethylcyclohexylamine, triethylene diamine, stannous octoate, dibutyl tin laurate and retardance catalyzer.
Described suds-stabilizing agent is prepare the common soft bubble of urethane or the suds-stabilizing agent used that hard bubbles.
Described whipping agent is water or water and the chloro-1-fluoroethane (HCFC-141B) of 1,1-bis-or water and dichloromethane mixture.
Described filler is mineral filler or organic filler.
After adopting such scheme, the present invention is compared with conventional urethane foam, and conventional urethane foam does not have water absorption character, cannot be degraded; The present invention utilizes crude vegetal based polyether polyol, adds extraordinary EO/PO(ethylene oxide/propylene oxide) base polyethers, full water is low-density foamed, environment friendly and pollution-free, can reach the characteristics such as water suction, degradable.
In a word, the polyurethane foam cotton structure that the present invention obtains is careful, perforate, environmental protection, there is excellent water suction, water retention capacity, can absorb and possess the moisture being multiple times than itself weight, and by filling a prescription, adjustment makes water suction, water conservation multiplying power be 10 ~ 35 times to the moisture of itself weight.
Test water-retaining method is: the foam cutting the common foam of equal densities same size and the present invention's description, weigh, be placed in the beaker of the amount of setting clear water, regularly (1h, 2h, 12h, 24h) take out foam afterwards and weigh, weigh to beaker, the weight that the water yield of beaker loss and foam increase is water regain simultaneously.
The present invention uses plant oil polyether, and the foam made by suitable method has good water suction, water-retentivity, has saved petroleum resources simultaneously.
