Abstract

A new-type wall powder also used as putty powder is made up of limestone, bentone, kaolinite, tolc, ultramarine and cellulose by crushing limestone and tolc, baking bentone and kaolinite, mixing, pulverizing and packaging, and features high whiteness and low cost.

Description

A kind of wall coating powder

The present invention relates to coating, specifically be meant a kind of wall coating powder.

Give birth to the raising of the level of drawing together along with the modern times, people are also more and more higher to the requirement of decorative paint, general coating can not satisfy people's requirement, as existing many coating is not because the too low needs that can not satisfy decoration of whiteness, be exactly because use a large amount of talcum powder, and cause cost too high for improving whiteness.

Purpose of the present invention just is the problems referred to above of existing at white coating, proposes a kind ofly with alternative a large amount of talcum powder, the kaolin of Wingdale, and then reaches the wall coating powder of whiteness height, effect that cost is low.

Wall plaster of the present invention comprises Wingdale, wilkinite, kaolin, talcum, ultramarine and Mierocrystalline cellulose.

The ratio of described each composition is (parts by weight are represented): Wingdale: 40-80 part; In the swelling: 3-15 part; On the high mountain range: 10-30 part, talcum: 5-20 part; Ultramarine: 0.05-0.1 part; Mierocrystalline cellulose 0.1-0.7 part.

The production method of described wall plaster comprises at first Wingdale, talc lump coarse crushing, in broken; With wilkinite, kaolin oven dry, according to the above ratio each component is mixed then, be crushed to certain fineness, packing gets final product.

Wherein, the granularity of coarse crushing is 40-60mm, and the degree of oven dry is to make the moisture content in wilkinite, the kaolin be lower than 8% (weight percent), and requiring fineness after the mixing is 325 orders.

Index request to the selected various components of the present invention is: it is that whiteness is more than 85 more than 95% that Wingdale requires its calcium carbonate content; The talcum whiteness is more than 85, and talc content can strengthen satiny more than 50; The kaolin whiteness can strengthen opacifying power more than 85; The wilkinite whiteness is more than 76,20 times of expansion multiples; Ultramarine can be selected the red chemical plant product that is in Tianjin for use, can go Huang to brighten; Mierocrystalline cellulose, as: carboxyl methyl cellulose sodium, can be used as thickening material, improve product sticking power, select chemical plant, Nangyuan District, Beijing product for use.

Wall plaster of the present invention is a white powder, nonpoisonous and tasteless non-corrosiveness, and strong covering power, water-soluble hardly and ethanol has soapy feeling, has good characteristics such as weathering resistance, resistivity against fire.

Wherein, the wall plaster specification of quality is: water content: 8-10%, and whiteness: 82-85%, fineness: 325 orders, percent of pass: 95%, opacifying power: 100g/m ²

In addition, the using method of wall plaster is: when using as inner wall paint, only need add 2-4 clear water doubly by weight, stir and can spray, brush.

Wall plaster of the present invention has the whiteness height, and the characteristics that cost is low are the real decoration good merchantable brands of suffering from of average family dwelling house and school's interior painting wall economy, in addition, can also use as putty powder.
