Abstract

The present invention discloses a paper-surface gesso plate, which is made of the following components according to weight ratio: 40-50 percent of gesso powder, 0.5-5 percent of active carbon, 0.5-1 percent of corn amylum and 0.4-0.8 percent of paper pulp fibre. Each raw material after being matched together with water is put into a mixer for milling, and then is to be pressed into a mould; the molded gesso plate is to be dried after being cut; the gesso plate after being dried is to be made with the second cut; finally, the products are packed and stored in the warehouse. Because active carbon is added into the gesso plate, by the test and detection in the house decorated with the gesso plate, the result shows that each residual organic volatile brought from the indoor fitment and other decorative materials can be adsorbed effectively; the adsorbing effect is 2-5 times better than that of the gesso plate without added with the active carbon. Besides, the present invention has the long-term and persistent absorption function. The present can avoid the disadvantage to the body health by the deleterious volatile. The manufacturing process is simpler and the social and economical benefits are much greater.

Description

A kind of Thistle board

Technical field

Invention relates to a kind of finishing material, relates in particular to the Thistle board of obnoxious flavoures such as a kind of adsorbable dimethylbenzene, formaldehyde.

Background technology

Gypsum adorned board is a kind of novel inner decoration material released of market in recent years, because it has cheapness, characteristics such as easy-to-use, thereby is used widely in the real estate of fast development and relevant finishing material industry.But since in the interior decoration process and the furniture production link generally use the tackiness agent, sanitas etc. of toxic volatile matters such as containing dimethylbenzene, formaldehyde, cause the long-term volatile matters such as residual dimethylbenzene, formaldehyde that slowly discharge of interior trim and furniture, HUMAN HEALTH is threatened, even become the stealthy killer of residents ' health.

Summary of the invention

The present invention is intended to use existing inner decoration material is improved, to overcome the prior art defective.

For achieving the above object, the present invention is characterized in that it comprises the raw material of following ratio of weight and number:

Terra alba 40～50 gacs 0.5～5 W-Gum 0.5～1 paper pulp 0.4～0.8.

Described each raw material optimum weight portion rate is:

Terra alba 45 gacs 3.5 W-Gums 0.7 paper pulp 0.5.

Also can include the whipping agent of 0.05～0.5 weight part in the described raw material.

Above-mentioned manufacture of gypsum board technology is:

Each raw material that a. will take by weighing and 26～28 parts of water are poured stirrer simultaneously into, fully stir the back extrusion molding;

B. the plasterboard with extrusion molding cuts the back oven dry, and the bake out temperature of drying and preheating region is 120～130 ℃, and hyperthermia drying district bake out temperature is 150～160 ℃, and oven drying at low temperature district bake out temperature is 80～90 ℃;

C. the plasterboard after will drying is packed warehouse-in after secondary cuts.

The technical progress that the present invention obtains:

(1). owing in existing gypsum adorned board, add gac, can eliminate foreign flavor indoors, to dimethylbenzene remaining in house decoration and the furniture, toxic volatile matter such as formaldehyde can produce tangible adsorption, premises through utilizing gypsum sheet material of the present invention to decorate compares the experiment detection and shows, the various remaining organic volatile that indoor furniture and other inner decoration material volatilize can obtain active adsorption, eliminate the peculiar smell effect and be the ordinary gypsum board that do not add gac 2～5 times, and has a secular lasting adsorption, can effectively avoid the disadvantageous effect of unwanted volatile to HUMAN HEALTH, can effectively improve resident's living environment, and production technique is simple, economic results in society are remarkable, have excellent popularization and utilize prospect.

(2). after interpolation has the whipping agent of tensio-active agent, can effectively reduce density of the present invention, form the product of Different Weight specification, to be used for various specific purposes.

Embodiment

Below in conjunction with specific embodiment the present invention is described further.

Embodiment 1:

Pour 200～250 order terra alba 45Kg, 60～100 order activity charcoal powder 3.5Kg, W-Gum 0.7Kg, paper pulp fiber 0.5Kg and the 28Kg water that take by weighing into stirrer simultaneously, fully stir the back extrusion molding, go into the stoving oven oven dry after then the plasterboard of extrusion molding being cut, oven dry divides preheating zone, high-temperature zone and cold zone, the preheating zone temperature is 120～130 ℃, the high-temperature zone bake out temperature is 150～160 ℃, the cold zone bake out temperature is 80～90 ℃, the plasterboard after the oven dry is carried out secondary cut back packing warehouse-in.

Other embodiment difference from Example 1 sees the following form.

Unit: (Kg)
