Description

The preparation method of paper face waterproof board

Technical field

The present invention relates to a kind of preparation method of new waterproof plate.

Background technology

At present, the dalle that decorations of the prior art are used mainly contains chemical sheet material and wooden boards.Chemistry sheet material is made with chemical substance, contains materials such as harmful formaldehyde, benzene, ammonia.Wooden boards needs a large amount of timber, not only can make the timber resources waste, and cost is also higher.

Summary of the invention

The preparation method that the purpose of this invention is to provide a kind of paper face waterproof board, this splash guard is made with string powder corn straw powder, straw powder, wheat straw powder, breeze and binding agent, and this product is nontoxic, pollution-free, waterproof fireproofing is good, body is light, environmental protection, intensity height, low, the long service life of cost.

The preparation method of paper face waterproof board is characterized in that this method may further comprise the steps:

1) raw material is formed; Paper face waterproof board is to be made by weight ratio by following compositions: string powder 10-50 part; Breeze 10-40 part; Binding agent 5-25 part; Waterproof mask paper 1-6 part; Water 10-30 part;

2) by the weight portion proportioning of described composition, after string dried, be ground into the powder that length is 0.1-0.4mm, standby; Breeze is ground into 800 orders-1000 order, standby;

3) the binding agent thin up is become pasty state, stir;

4) at room temperature, with the breeze after string powder after the above-mentioned pulverizing and the pulverizing, and binding agent mixes behind the dilute with water, fully stirs, and mixes; Then waterproof mask paper is placed on the top of said mixture and below, be that 5MPA, temperature are that heating stops pressurization under 150 ℃ the condition after 2 minutes at pressure, formed the paper face waterproof board material;

5) be to be cooled to 70 ℃ under the 5MPA condition with above-mentioned paper face waterproof board material at pressure, carry out the corner with bead cutter and handle that be made into standard-sized sheet material, after surface treatment, packing is put in storage again.

The present invention compared with prior art, its novelty and creativeness are embodied in:

1) this splash guard is made with string powder corn straw powder, straw powder, wheat straw powder, breeze and binding agent, and this product is nontoxic, pollution-free, waterproof fireproofing is good, body is light, environmental protection, intensity height, low, the long service life of cost.

2) make full use of waste resource, the raw material that the present invention uses is crops straw and abandoned mine powder, and discarded resource is utilized effectively, and reduces cost.

3) the present invention does not on the make produce waste water and gas, and environment protecting is good.

4) of many uses, the present invention can be used for decorations such as train, automobile, ship and indoor, outdoor wall, partition, ceiling and uses.
