Abstract
The present invention is that a kind of writing used paper, and it is made up of paper substrate and chemical composition, can be stained with clear water with pen during use and write on paper, can show black font immediately, treats to disappear immediately after water is done.A piece of paper can use more than 1,000 times repeatedly, can extensively practise writing of writing brush, pen as the student.
Description
The present invention relates to a kind of writing paper produce and using method can be used for practising writing of writing brush, pen.
The paper shortage is on the rise, and the waste of paper is also quite outstanding simultaneously.Because existing to write paper all be disposable, is difficult to reach the repeated use of paper, is repetition and have many in actual life with paper, practise with paper, work out a draft etc. as people.In addition, also occurred the paper that a kind of several uses on the market, but all because of complex manufacturing technology, quality is low and extensively promoted.
The objective of the invention is to avoid the weak point in above-mentioned existing use and the technology and provide a kind of composition and technology simple, the compound paper capable of writing with water that quality is high.
Purpose of the present invention can reach by following measure, is coated with the last layer mixture on the common paper basis, and this kind mixture can show black under the situation with the water contact, take off for not causing developing mixture, increases layer protective layer on developing mixture again.Prescription is: carbon black 5.5-6.3%; clear water 27-32%; polyvinyl alcohol 7-8.5% Gao Ling soil 48-56%, resin glue 1-1.3%, chemical pure 0.15-0.2%; glycerol 1-1.3%; absolute ethyl alcohol 1-1.3%, salinization sodium 0.3-0.4%, above-mentioned prescription is undertaken by following technology successively: carbon black 5.5-6.3% will fill a prescription earlier; clear water 27-32% polyvinyl alcohol 2.3-3% mixes; because carbon black floats on the surface, therefore should heat mixture, make it mix And and be coated in mixture on the paper substrate equably; to fill a prescription again behind the airing and be: Gao Ling soil 48-56%, polyvinyl alcohol 4.7-5.5%, resin glue 1.1%; chemical pure 0.15-0.2%; glycerol 1-1.3%, absolute ethyl alcohol 1-1.3%, the protective agent of salinization sodium 0.3-0.4% is coated and can be used.
How much high Ling soil content in the protective agent is as toning usefulness, and salinization sodium can be used can.
Be described in further detail below in conjunction with embodiment, will fill a prescription is: carbon black 5.54%, and clear water 27.7%, polyvinyl alcohol 2.494% mixes, and molten device is decided by the size of formula ratio.At the carbon black that the water surface is floating, be difficult for making its dissolving, therefore need heat and make the carbon black dissolving.After the cooling developing mixture for preparing is coated in airing on the paper substrate equably.To fill a prescription in another molten device is: Gao Ling soil 55.43%, polyvinyl alcohol 4.99%, and resin glue 1.1%, chemistry is ignorant 0.166%, glycerol 1.1%, absolute ethyl alcohol 1.1% after the protective agent preparation of salinization sodium 0.33%, is coated on the developing mixture, promptly makes compound paper capable of writing with water.
The invention has the advantages that: paper is after above-mentioned technology, prescription are made compound paper capable of writing with water, reusable more than 1000 times on this paper. Popularization of the present invention has good impetus for saving paper using alleviation paper short supply state.
