Abstract

Provided is a raw material formulation for preparing special building mould and a relative production process, which comprises polypropylene 40 parts by weight, brucite 20 parts by weight, talcum powder 5 parts by weight, coupler 4 parts by weight, polyethylene wax 2 parts by weight, wood powder 5 parts by weight, stabilizer 2 parts by weight and stearic acid 15 parts by weight. The special building mould prepared according to the raw material formulation and producing technique can be used in the building engineering and the using number of turnover is much more than glued board and bamboo plywood, which is light in weight and low in cost belonging to national promoted sub-circulated economical and environment-friendly product categories due to circulating utilization without toxicity, odor and pollution. The property indexes such as extension strength, impact strength, bending strength, combustion property and the like meet standard requirement.

Description

Produce building raw materials used proportioning of dedicated templates and production technique

Technical field

The present invention is a kind of production building raw materials used proportioning of dedicated templates and production technique.

Background technology

Along with the develop rapidly of Building Trade in China, housing-group miscellaneous is rised sheer from level ground like the mushrooms after rain throughout the country, and the development of construction industry has also directly brought the increase to conventional template timber, wooden form, glued board, bamboo offset plate demand.This is populous for one, and the country that the forest reserves are deficient relatively makes the matter worse.At present, employed glued board, bamboo offset plate all adopt the tackiness agent that contains formaldehyde, and the producer of the glued board of producing this type of in all parts of the country is thousands of, produce poisonous glued board every day and we can say and wantonly describe with astronomical figure.

Because building form does not belong to the building structure product, it is " circulation material ", " replacement appliances ", " consumable products " in the construction work, so country and relevant department do not attach great importance to the negative effect after building template uses in whole use, a large amount of building template refuse pollutions urban environment, its poisonous element pollution know clearly the earth, air, and river, river, lake, sea have been polluted with rainwash, the knowledgeable people is being perplexed in the development of substitute products for many years always, is expected by people with the environmentfriendly products of moulding wooden reusable edible of generation.

Summary of the invention

The objective of the invention is to, solve above-mentioned existing existing problem, provide a kind of and produce building raw materials used proportioning of dedicated templates and production technique with the environmentfriendly products of moulding wooden reusable edible of generation.

The present invention is achieved in that by weight, adopts following proportioning raw materials: polypropylene 40-60, brucite 20-40, talcum powder 5-10, even stick 4-8, Ployethylene Wax 2-5, wood powder 5-10, stablizer 2-4, dicalcium powder 10-20, stearic acid 15-30; Its production technique is, get material by said ratio, earlier brucite, talcum powder, wood powder, dicalcium powder are put into stirrer and be stirred to 140-160 ℃, and then put into remaining other material polypropylene, even stick, Ployethylene Wax, stablizer, stearic acid and stir, when arriving 160 ℃, temperature stirred 5 minutes; In 15-20 minute, be cooled to 5-10 ℃ rapidly then, again material put into forcing machine, extrude, cut into desired size, be building dedicated templates finished product through electric saw.

Advantage of the present invention is, press the building dedicated templates that above-mentioned raw materials proportioning and production technique are made, can be used for construction work, as Industrial buildings, covil construction, highway, bridge, culvert, tunnel, underground works etc., the number of turnover that uses is higher than glued board, bamboo offset plate far away, in light weight, price is low because recycle is nontoxic, tasteless, pollution-free, belongs to country and advocate back recycling economy, environmentfriendly products category.All conformance with standard requirements such as its performance index such as tensile strength, shock strength, flexural strength, combustionproperty, the Detailed Inspection report.

Embodiment

Example 1

Get polypropylene 40kg, brucite 20kg, talcum powder 5kg, even stick 4kg Ployethylene Wax 2kg, wood powder 5kg, stablizer 2kg, dicalcium powder 10kg, stearic acid 15kg; After getting material by said ratio, earlier brucite, talcum powder, wood powder, dicalcium powder are put into stirrer and be stirred to 140-160 ℃, and then put into other material and stir, stirred 5 minutes when temperature arrives 160 ℃; In 15-20 minute, be cooled to 5-10 ℃ rapidly then, again material put into forcing machine, extrude, cut into desired size, be building dedicated templates finished product through electric saw.

Example 2

Get polypropylene 60kg, brucite 40kg, talcum powder 10kg, even stick 8kg, Ployethylene Wax 5kg, wood powder 10kg, stablizer 4kg, dicalcium powder 20kg, stearic acid 30; After getting material by said ratio, earlier brucite, talcum powder, wood powder, dicalcium powder are put into stirrer and be stirred to 140-160 ℃, and then put into other material and stir, stirred 5 minutes when temperature arrives 160 ℃; In 15-20 minute, be cooled to 5-10 ℃ rapidly then, again material put into forcing machine, extrude, cut into desired size, be building dedicated templates finished product through electric saw.
