Abstract
The invention discloses a preparation method of a white coating agent containing polyvinyl alcohol. The preparation method comprises the following steps: a. mixing polyvinyl alcohol with water in a mass ratio of (1:10)-(1:14), heating the mixture to 85-95 DEG C until polyvinyl alcohol is completely dissolved in water and obtaining polyvinyl alcohol stock solution after cooling; and b. mixing the polyvinyl alcohol stock solution prepared in the step a with the raw white coating agent in a mass ratio of (1:8)-(1:12) and stirring the mixture fully and uniformly. The preparation method has the advantages of time, labor and cost saving and good effect.
Description
Technical field
The invention belongs to the fruit trees protection field, refer in particular to the preparation method of a planting fruit-trees coating drying agent.
Background technology
To winter, fruit tree need to be coated with dry treatment, namely brushes one deck white-out agent on trunk and major branch, with insect-pest, day bright and freeze injury.After entering the winter, day and night temperature is large, and daytime, the sunny slope of trunk was subjected to solar radiation, and temperature is higher, and cortex absorbs high heat, and the cortical cell that is full of moisture is thawed; To night, cortical cell is subjected to the impact of extraneous low temperature, and in cell, moisture freezes again.Such heat one is frozen, can be with the cortical cell frostbite.After being coated with dry treatment, can reflected sunlight due to the white of white-out agent, can make trunk keep stable lower temperature, allow the cortical cell of trunk unlikely because violent variations in temperature occurs frostbite.But need to be coated with twice like this, waste time and energy.Present general white-out agent, if coating is too thin, the color at coating place is not white, do not play reflection action, if too thick, the air-dry rear cracking of coating, and stick up outward, coating comes off easily, adheres to that the time is short, do not have burnt in long-term anti-day, effect that frost damage prevention, sterilization are controlled worm.Be coated with at present while doing, generally need twice of brushing.
Summary of the invention
The technical issues that need to address of the present invention are to provide the preparation method of the fruit tree coating drying agent of a kind of time saving and energy saving province expense.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Contain the preparation method of the white-out agent of polyvinyl alcohol, comprise the following steps, a, polyethylene alcohol and water mix according to mass ratio 1:10～1:14, are heated to 85～95 degrees centigrade, treat that polyvinyl alcohol all is dissolved in water, dry in the air after cool and are polyethylene alcohol basic solution; B, polyethylene alcohol basic solution and white-out agent raw material that a step is made mix and stir according to mass ratio 1:8～1:12.
Described white-out agent raw material according to mass fraction by 40～60 parts of quicklimes, 4～6 portions of salt, 4～6 parts of lime sulfurs, 200 parts of water mixing and stirring and obtain.
Owing to having adopted technique scheme, the obtained technological progress of the present invention is:
The present invention both can reach sterilization, thermal effect, and was more without any side effects.Polyvinyl alcohol has very strong adhesivity after boiling, air-dry rear stationarity is strong, can make white-out agent firmly stick to the bark surface, thickness difficult drop-off no matter while smearing, the white-out agent that method of the present invention makes, color is pure white, and the duration is long, until grow next year, can both play protective action before season.The white-out agent that uses method of the present invention to make, only need brushing once can reach requirement, thus the saving of labor, save time, cost saving again.
Embodiment
Below in conjunction with embodiment, the present invention is described in further details:
Embodiment 1
At first be to prepare polyethylene alcohol basic solution, the polyethylene alcohol and water is mixed according to mass ratio 1:10, be heated to 85 degrees centigrade, treat that polyvinyl alcohol all is dissolved in water, dry in the air after cool and be polyethylene alcohol basic solution.Then take 40 parts of quicklimes, 4 portions of salt, 4 parts of lime sulfurs, 200 parts of water mixing and stirring according to quality, make the white-out agent raw material.Finally polyethylene alcohol basic solution and white-out agent raw material are mixed to stir according to mass ratio 1:8 and namely can be made into the white-out agent that contains polyvinyl alcohol.
2010 green faces base 60,000 strain walnuts and is coated with the white-out agent that contains polyvinyl alcohol, from mid-October, 2010 brushing, and outer sticking up not, weather proof Exposure to Sunlight, all play insect-pest, sterilization in April, 2011, burnt in anti-day, the frost damage prevention effect.And Lv Ling base walnut in 2010 is whitewashed with traditional white-out agent brushing walnut, and autumn in 2010, once spring in 2011 once, just can reach the effect that the white-out agent that contains polyvinyl alcohol plays.The white-out agent successful that contains polyvinyl alcohol, the while also reaches the saving of labor, saves time, economizes the purpose of expense.
Embodiment 2
At first, the polyethylene alcohol and water is mixed according to mass ratio 1:14, be heated to 95 degrees centigrade, treat that polyvinyl alcohol all is dissolved in water, dry in the air after cool and be polyethylene alcohol basic solution.Then take 40 parts of quicklimes, 4 portions of salt, 4 parts of lime sulfurs, 200 parts of water mixing and stirring according to quality, make the white-out agent raw material.Finally polyethylene alcohol basic solution and white-out agent raw material are mixed to stir according to mass ratio 1:12 and namely can be made into the white-out agent that contains polyvinyl alcohol.
2011 green faces the walnut of planting autumn in base, survives the winter, winter protection adopts three kinds of different disposal methods: 1, with the white-out agent brushing that contains polyvinyl alcohol, and 2, with common white-out agent brushing, 3, with being coated with again polyethylene alcohol basic solution after common white-out agent brushing.Its result: with common white-out agent brushing, because trunk is thinner, the time of a wheat harvesting period, just stick up outward, come off, do not have due effect; After being coated with the brushing of polyvinyl alcohol method after the white-out agent of this formula and common white-out agent brushing, the duration is long again, can arrive April in coming year bud and sprout; Moreover the white-out agent of this formula is few man-hour, cost saving.
Embodiment 3
At first, the polyethylene alcohol and water is mixed according to mass ratio 1:12, be heated to 90 degrees centigrade, treat that polyvinyl alcohol all is dissolved in water, dry in the air after cool and be polyethylene alcohol basic solution.Then take 40 parts of quicklimes, 4 portions of salt, 4 parts of lime sulfurs, 200 parts of water mixing and stirring according to quality, make the white-out agent raw material.Finally polyethylene alcohol basic solution and white-out agent raw material are mixed to stir according to mass ratio 1:10 and namely can be made into the white-out agent that contains polyvinyl alcohol.
In polyethylene alcohol basic solution of the present invention, the ratio of polyethylene alcohol and water can also be the arbitrary proportion from 1:10～1:14, the arbitrary proportion that the ratio of the quicklime in the white-out agent raw material, salt, lime sulfur is all right 40～60 parts, 4～6 parts, 4～6 parts.Lime sulfur can add water with quicklime, sulphur and boil and form, and the parts by weight ratio of three's the best is 1:4:10.
