Abstract
The present invention relates to a method for preparing a faced blackboard material. The faced blackboard material comprises the following components according to the proportion by weight: 100 shares of polyethylene or polyvinyl chloride as a main ingredient, 15 to 20 shares of red mud as filling materials, 5 to 15 shares of black carbon, 10 to 20 shares of chloroprene rubber, 150 to 200 shares of heavy calcium carbonate, 80 to 100 shares of emery powder, 10 to 15 shares of polyamide, 10 to 15 shares of acrylic ester or polyamine ester and an auxiliary agent thereof. The faced blackboard material is prepared by milling and calendering all materials. When being used, the faced blackboard material is stuck onto a plane sheet material by glue. The faced blackboard material has the advantages of fineness, elasticity, good hand feeling, easy fabrication, low cost and easy popularization.
Description
The invention discloses a kind of process for preparing faced blackboard material, belong to the teaching equipment field.
Blackboard is the important teaching equipment in teaching and the cultural activity, and a kind of resin blackboard is arranged on the market, be with unsaturated resin or phenolic resin blade coating on flat panel substrates, forming through grinding.This blackboard good rigidly wear resistance is good, is subjected to teacher's welcome.But some shortcoming of elasticity, feel is also not ideal in the use.There is price higher again, is less compliant in the economically underdeveloped area and promotes.
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, a kind of increase elasticity be provided, good hand touch frictional force appropriateness, reduce production costs the blackboard material that is adapted at pasting on the flat sheet.
The objective of the invention is to realize by following measure, a kind ofly make through mixing calendering by major ingredient polyethylene or polyvinyl chloride, filler red soil, carbon black and conventional auxiliary agent, its characteristics are also to add in the raw material antiaging agent paracril or chloroprene rubber, elasticator acrylic acid ester or urethane, toughener polyamine and slipproofing agent GL ground limestone and lapis amiridis, its prescription is:
Major ingredient, polyethylene or polyvinyl chloride 100 weight parts
Filler, red soil 15-20 weight part
Carbon black 5-15 weight part
Antiaging agent, chloroprene rubber or paracril 10-20 weight part
Elasticator, acrylate or urethane 10-15 weight part
Slipproofing agent, GL ground limestone 150-200 weight part
Lapis amiridis 80-100 weight part
Toughener, polyamine 10-15 weight part
Above-mentioned materials is through mixing, and calendering is made.
Blackboard material provided by the present invention can stick on the flat sheet and can use with 401 or 801 glue.This blackboard material is in use fine and smooth, flexible, good hand touch, frictional force appropriateness.This blackboard material transports easily, and paste operation is simple and convenient.Not reflective, non-slip in the use, easy-to-write and erasable has better weather, water-fast and wearing quality, is fit to teacher's use habit.Because it is suitable to add acrylic acid ester or urethane and slipproofing agent proportioning, chalk wearing and tearing appropriateness is slow, therefore reduces the chalk dust dust quantity.This blackboard material production technique is simple, production in enormous quantities easily, low production cost, popularization easily, after some waste and old blackboards need only and repair, surfacing, pasting faced blackboard material of the present invention can repair sth. old and make it as good as new, and is fit to use in economically underdeveloped area school and the daily culture activity.
Below in conjunction with embodiment the present invention is described in further details.
Embodiment 1: by following prescription batching
Polyvinyl chloride 100 weight parts
Red soil 15 weight parts
Carbon black 8 weight parts
Paracril 15 weight parts

GL ground limestone 190 weight parts
Lapis amiridis 80 weight parts
Polyamine 10 weight parts
Other auxiliary agent routines are allocated into
Through mixing, it is 1-1.5mm that thickness is made in calendering with above-mentioned materials, and width 1.0-1.2 rice coiled material is got surfacing plank or cement or Glass blackboard and coated 401 glue or 801 glue during use, stick faced blackboard material of the present invention and make.
Embodiment 2:
Polyvinyl chloride 100 weight parts
Red soil 17 weight parts
