Problems solved by technology

In addition, Xinjiang is the largest cotton-producing area in my country, and countless cotton stalks are produced every year; Xinjiang alone uses more than 100,000 tons of plastic film every year. If these wastes are not used, they will bring great harm to the environment.

Embodiment Construction

[0014] The ingredients of the components of the embodiment of the present invention are shown in Table 1.

[0015] The process is as follows:

[0016] 1. Raw material preparation and pretreatment: granulate waste wood and cotton stalks and granulate waste plastics such as recycled waste mulch polyethylene;

[0017] 2. Dry with wood flour dryer, hot air dryer, microwave dryer, etc.;

[0018] 3. Mix the ingredients and add modifiers, anti-aging agents, tackifiers, lubricants, flame retardants and other additives at the same time;

[0019] 4. Molding: pressurized and stretched into the initial shape, the temperature is 80-120°C during molding, and the pressure is 0.6-1.2Mpa for at least 10 minutes;

[0020] 5. Cooling;

[0021] 6. Cutting and making finished templates: length x width x thickness = 1500mm x 900mm x 10-15mm.

[0022] Performance test results: all meet the requirements of the acceptance indicators shown in Table 2. The static bending strength shall be carried o...

Abstract

The invention provides the preparing method of wood mold. The method comprises 55-75 parts waste wood slag, 55-75 parts cotton particles, waste vinyon and 15-30 parts polyvinyl resin and auxiliary agent; the bending strength of product is above 45N / mm2, impact strength is above 35KJ / m2, elasticity modulus is above 3*103N / mm3, and retention intensity is above 35N / mm2. The method comprises the following steps: pelleting, mixing, adding auxiliary agent, and moulding. The mold has the advantages of high strength, non-deforming, repetitive-use, easy dismounting, high economic profit and wide usage. The method has the advantages of simple technology, low cost, and environmental protection.

Description

technical field [0001] The invention relates to the technical field of building formwork, in particular to a plastic-wood formwork and a production method thereof. Background technique [0002] my country is a country with a low forest coverage rate. In order to protect forest resources and ecological environment, the country has adopted measures to limit logging and promote the use of wood substitute materials. In addition, Xinjiang is the largest cotton-producing area in my country, and countless cotton stalks are produced every year; Xinjiang alone uses more than 100,000 tons of plastic film every year. If these wastes are not used, they will bring great harm to the environment. Contents of the invention [0003] The purpose of the present invention is to provide plastic-wood formwork and its production method. The plastic-wood formwork of the present invention has the characteristics of light weight, high strength, no deformation, low cost, reusability, high economic b...
