Abstract
A table tennis table top made of novel materials is formed by light calcined magnesia, magnesium chloride aqueous solutions, filler powdered coal, sawdust and modifiers according to certain weight percentages. The table tennis table top is made in the steps that the raw materials of magnesium chloride and the filler powdered coal are added into a mixer to be mixed and blended uniformly, then the magnesium chloride aqueous solutions are poured into the mixer to be mixed, then the modifiers are added into the mixer to be mixed, a template is placed on a molding machine, two layers (an upper layer and a lower layer) of glass fiber cloth are laid on the template, magnesium cement sizing agents are formed between the upper layer and the lower layer, a top layer and a bottom layer are formed by magnesium cement through four-time continuous roller forming, demolding is carried out after all the materials are placed on the template for 24 hours, and then the table tennis table top is maintained in a maintenance room with a preset temperature and humidity. The table tennis table top is high in strength, good in elasticity, free of deformation, capable of being nailed and sawn, good in water resistance, wide in types of raw materials, low in price, capable of being used outdoors, capable of replacing timber and protecting the environment, and simple in manufacturing.
Description
Technical field
The present invention relates to a kind of court of New Type Material, belong to the cement building material field.
Background technology
Traditional court is all to using timber or cement as starting material, then surface is aided with rubber or plastics, the timber of usining is not only wasted national resources as the court starting material, and poor water resistance is not suitable in outdoor application for a long time, and the starting material cost of investment is higher; Using cement as court, and weight is large, poor flexibility, and long-term poor water resistance.At present more for research is accessibility and the handiness of ping-pong table integral body, for example, collapsible, built-up type and multi-functional, and less to the research of court base material.The magnesia oxychloride cement formed with magnesium oxide and magnesium chloride, with the characteristic of its natural excellence, the industries such as building materials, packing that are not widely used in such as strong as high-strength, wear-resisting, fire prevention, cohesive force.
The present invention will overcome existing deficiency exactly, and a kind of court of New Type Material is provided.This court intensity of the court of this material is high, good springiness, can follow closely, can saw, water resisting property is good, starting material are extensive, cheap, manufacture simple.
Summary of the invention
The problem to be solved in the present invention is: the court that a kind of New Type Material is provided, this court is usingd the magnesia oxychloride cement that magnesium oxide and magnesium chloride form, and as material, manufacture forms, and lay layer glass fiber (each one deck up and down) in manufacturing processed, the court of this New Type Material has the advantages such as intensity is high, toughness is large, durable in use, and weight is lighter, is conducive to transportation and installs, can be used for indoor and outdoor, life-span is long, makes simply, but life-time service.
In order to address the above problem, the present invention is achieved through technology.
A kind of court of New Type Material, it is by light calcined magnesia, magnesium chloride brine, stopping composition fine coal, wood chip, properties-correcting agent forms according to the configuration of certainweight per-cent, its step is for entering starting material magnesium oxide and stopping composition fine coal in stirrer and stir it is mixed, again magnesium chloride brine is poured in agitator and stirred, again properties-correcting agent is joined in agitator and stirs, template is placed on to forming machine and lays layer glass cloth (each one deck up and down), middle one-tenth is the magnesium cement slurry, top layer and bottom are that magnesium cement is through continuous four rolls forming, place the demoulding after 24 hours on template, then maintenance in setting the curing room of temperature and humidity.This court intensity is high, good springiness, indeformable, can follow closely, can saw, water resisting property is good, starting material are extensive, cheap, can be used for outdoorly, can replace timber, environmental protection, manufacture simple.
The content of light calcined magnesia is 40%～50%.
Magnesium chloride brine content is 30%～40%.
(phosphoric acid: SODIUM PHOSPHATE, MONOBASIC: zinc sulfate=1:1:3), content is between 0.1%～10% must to add a certain amount of properties-correcting agent in starting material.
Filler in wood chip, flyash, silicon ash, pearlstone, calcium carbonate crystal whisker, diatomite a kind of, two or three form
Properties-correcting agent phosphoric acid salt is one or more compositions in tertiary sodium phosphate, SODIUM PHOSPHATE, MONOBASIC, trimagnesium phosphate and tripoly phosphate sodium STPP
Properties-correcting agent vitriol is one or more compositions in sal epsom, Tai-Ace S 150, calcium sulfate, rose vitriol, zinc sulfate
Woven fiber glass is medium-alkali glass fibre
Adopted technique scheme, the invention has the beneficial effects as follows:
The court intensity of this material is high, good toughness, good springiness, quality are light, convenient transportation and installation, indeformable, can follow closely, can saw, water resisting property is good, outdoor standing, exposes to the weather, the life-span is long, but life-time service, and starting material are extensive, cheap, solved greatly Financial cost, manufacture simple, easy to operate, environment friendly and pollution-free.
Therefore, the outstanding advantages of the court of this New Type Material is: the court intensity of (1) this material is high, good toughness, good springiness, quality are light, convenient transportation and installation, and long service life, but life-time service (2) starting material are extensive, cheap, solved greatly Financial cost, manufacture simple, easy to operate, environment friendly and pollution-free
The court of New Type Material of the present invention, starting material are extensive, make simple, be easy to transportation and install, greatly saved Financial cost, and environmental protection do not pollute, good toughness, good springiness, water resisting property are used on outdoor standing and expose to the weather in addition, effectively extended the life-span, but life-time service.
