Abstract
The invention relates to a teaching blackboard, in particular to environment protection wet coating agent of a blackboard and a preparation method thereof. The coating agent of the invention is made of following raw materials by weight: 10 to 30 proportions of egg white, 30 to 70 proportions of plant starch and 500 to 1500 proportions of water. The preparation method is that the plant starch and the water are put into a container to be heated and stirred; when the mixture is heated to become paste at the temperature of 100 DEG C and cooled, the egg white is added and fully stirred and then the finished product is obtained. The invention is a water soluble natural polymer compound; after being sprayed on the blackboard and dried, the invention can form a layer of wet membrane that is extremely thin, hard and wipe resistant, and a blackboard pen can write smoothly on invention, and the membrane is easily cleaned. Research and preparation of the invention is an unavoidable technical reform based on comparison of the isolation technology of environmental protection wet blackboard writing polymer synthesized sticking membrane produced by Guangzhou Ocean Environmental Protection Technology Co., Ltd.; proved by practice, the coating agent combined by natural polymer and natural polymer organic matter is easier to clean than synthesized polymer membrane when applied to blackboards of schools; without toxicity, pollution, and harm to human body, the invention is environmental protective and can greatly reduce cost.
Description
Technical field
The present invention relates to blackboard for education, refer in particular to blackboard environment protection moisture coating agent and preparation method.
Background technology
A kind of water-based writing on the blackboard pen is arranged at present, and this pen can not directly write on blackboard, must paste the synthetic macromolecule plastic film of one deck costliness before writing and isolate blackboard on blackboard, word write on just be convenient to wiping on the film, but this film costs an arm and a leg, and use cost increases, and is difficult to promote.
Summary of the invention
The objective of the invention is to be improved, innovate at the shortcoming and defect in the background technology, provide a kind of cost low, technology is simple, blackboard environment protection moisture coating agent easy to use and preparation method.
It is to be made by the raw material of following weight part that the present invention applies agent:
Egg white 10-30, plant amylum 30-70, water 500-1 500.
Optimum weight part proportioning that the present invention applies agent is:
Egg white 25, plant amylum 50, water 1000.
Above-mentioned each component is made the production method that the present invention applies agent is:
Starch and water are put into molten device heat, heat and stir simultaneously, heating to 100 degree becomes pasty state, adds egg white after cooling, stirs existing product again.
The present invention is a kind of water-soluble natural polymeric composition, and spary just forms one deck moist film of hard and anti-wiping as thin as a wafer after doing on the blackboard, make a writing on the blackboard fluent writing, gets final product wiped clean easily.Development of the present invention be according to the contrast of the isolation technology of the gloomy environment-friendly water-based writing on the blackboard Polymer Synthesizing pad pasting of Guangzhou Australia the road of a technological transformation must walking, confirm in practice, the coating agent that natural polymer and natural polymer are organically combined is used for the easier wiping examination of school's blackboard than the polymer pad pasting of synthetic, and reduce cost greatly, nontoxic, pollution-free, environmental protection, harmless.
The present invention and the contrast of the traditional product impact of performance:
Embodiment
Embodiment
Take by weighing raw material (gram) by following proportioning:
Egg white 25, plant amylum 50, water 1000.
Production method is as follows:
Starch and water are put into molten device heat, heat and stir simultaneously, heating to 100 degree becomes pasty state, adds egg white after cooling, stirs existing product again.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; do not breaking away under the preceding topic of design philosophy of the present invention; engineering technical personnel make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
