Problems solved by technology

The existing water writing paper mainly has the following defects: 1. The number of times of reusability is small, and after several times of use, the paper will become wrinkled when exposed to water, resulting in waste of normal use. 2. The contrast when writing is poor, resulting in poor writing. Significantly reduces the effect of the exercise

Embodiment

[0019] This embodiment provides a water writing paper, including a functional layer, a color development layer and a base material layer arranged in sequence from top to bottom, and the three are combined to form the new water writing paper, wherein:

[0020] The substrate layer replaces the ordinary paper used in the existing water writing paper. It is made of calcium carbonate powder as the main raw material, plus polyethylene with a mass ratio of 10% to 20% and a binder with a mass ratio of 3% to 10%. For synthetic paper, the amount of polyethylene is preferably 15%. According to different needs, the amount of polyethylene can also be 11%, 12.5%, 13%, 14%, 15.5%, 18%, 19%, etc.; The dosage is preferably 5%, and according to different requirements, the dosage of the adhesive can also be 4%, 6%, 5.5%, 8%, 7%, 9%, etc. Among them, calcium carbonate powder is preferably ground into powder with stones.

[0021] The color-developing layer, generally black, is used to create a co...

Abstract

The invention discloses a piece of novel water writing paper, and solves the problems that existing water writing paper is indistinct in handwriting, and poor in writing effect. The novel water writing paper comprises a functional layer, a color development layer and a base material layer which are successively arranged from top to bottom and are compounded to form the novel water writing paper, wherein the base material layer is synthetic paper prepared from calcium carbonate powder used as a main raw material, and polyethylene with the mass ratio is 10%-20%, and an adhesive with the mass ratio is 3%-10%; the color development layer is prepared from high-blackness carbon powder used as a raw material, and a water-proof abrasion-proof polishing oil used as an adhesive of the carbon powder; the functional layer is prepared by mixing titanium dioxide with a water-proof abrasion-proof acrylic resin, and completely covers the color development layer. The novel water writing paper disclosed by the invention is simple in structure, the frequency of use of the water writing paper is greatly increased, and the writing effect is improved through the improvement on the functional layer, the color development layer and the base material layer.

Description

technical field [0001] The invention relates to a water writing paper, in particular to a novel water writing paper. Background technique [0002] Water writing paper is a durable paper that is advanced and popular in China, replaces ink with water, and can be used repeatedly. Easy to carry, simple to use, just use water. Since the water writing paper can be used repeatedly thousands of times, a piece of water writing paper can save thousands of ordinary paper, saving both paper and paper. The existing water-based writing paper mainly has the following defects: 1. The number of times of reusability is small, and after several uses, the paper will become wrinkled when exposed to water, which will cause it to be unable to be used normally and cause waste. Significantly reduces the effect of the exercise. Contents of the invention [0003] The purpose of the present invention is to overcome the above defects and provide a new type of water writing paper with good writing c...
